6 Feldspar, 7 quartz, 8 Topaz, 9 Corundum, 10 Diamond
BASALT
Basalt is the most common of the earth's volcanic rocks, its crystals are
continuous and elongated. Basalt magma is sometimes as hard as glass,
but rarely.
SYENITE
Syenite forms in silicate-less magma, consisting typically of feldspar and
hornblende.
QUARTZ
Quartz is the most common crystal mineral, oxygen and silicon, it has the
hardness of H7. Quartz is found in ore mineral veins and needs a hollow
space to form, As rocks and veins weather, quartz is freed of its matrix and
breaks loose to form sand. Cemented sand is sandstone. Intruding magma
going through sandstone will again form ore and quartz.
GRANITE
Granite is also igneous, fire intrusive. It's composed of quartz and feldspar. Granite magma intrudes limestone or dolomite and forms marble. Marble is heat and calcium of limestone, plus calcium magnesium of dolomite, plus silica. Veins or lodes of ore in marble include, tin, copper, uranium, iron, zinc and lead. Marble is metamorphic limestone.
Granite intrudes with its hottest leading edge forming cassiterite, tin.
The copper sulfides form second, chalcopyrite is the primary copper ore
formed in quartz. Third would be cobalt, nickel and arsenic. Then the zinc-lead
zone, with zinc sulfide as sphalerite ore, lead sulfide as galena ore, than
silver. Finally, the iron rich zone with iron carbonate as siderite ore, the
dominate mineral of the world.
FELDSPAR
Feldspar is common in granite magma intruding on sandstone sedimentary rock, it hardens into a crystal softer then quartz. Feldspar can be morphasized with pressure to a harder crystal like tourmaline or topaz.
Feldspar is the second most common mixed mineral silicate crystal, made from potassium, sodium and calcium, an alumino-silicate. It contains aluminum in the ore, bauxite, clay and rock. Clay is hydrated silicates of aluminum.
Potash feldspar is microdine, add iron and it takes on red to green colors. Green amazonite was mined and used as a pigment on murals in 1300 B/C, in Egypt.
Plageoclase feldspar is sodium and calcium.
KAOLINITE
Kaolinite, is clay and chalk after feldspar. Carbonic acid, is present in rainwater or vapors, this pheudomorphs the kaolinite from feldspar.
Porcelain is made from kaolinite clay and is mined in Cornwall, England
and China.
SANDSTONE
Sandstone is a sedimentary rock, an intact mineral of quartz sand. It is
cemented together by the commonest cement, calcium carbonate.
QUARTZITE
Quartzite is metamorphic sandstone, an intact mineral or solution of
suspended silica growing on quartz crystal, sand is broken quartz
crystal.
LIMESTONE
Limestone is a sedimentary mineral cemented by calcium carbonate and is
made of once living organisms, the dissolved mineral is calcite. In this
same category of sedimented rock is salt and gypsum. Powered and heated,
"calcined" limestone makes plaster of Paris, mural mortar, we'll get to
slaking lime in the mural chapter in Mediums Explained.
MARBLE
Marble is metamorphic or recrystallized limestone, being metamorphic is
being made with pressure.
GYPSUM
Gypsum's are crystals of hydrous calcium sulfate, crystal deposits formed as precipitates from sea water or in limestone, These circulating waters contain sulfuric acid generated by oxidation of sulfur ore minerals.
Gypsum crystals are called selenite when there clear, alabaster, when there translucent and fibrous, satin-spar, when there opaque and bendable.
Gypsum heated forms sulfur dioxide gas and sulfuric acid. Heated in the
presence of lead, either with fumes or in a natural combinations, will form
basic lead carbonate, called lead white. Gypsum, after being heated loses most
of its sulfur and becomes plaster of Paris, lime plaster is better to paint on.
HORNFELS
Hornfels are a combination of clay and fine quartz sand, forming silt
which makes shale. Pressure forms hard rock hornfels.
DIATOMITE
Diatomite is diatomaceous earth, a porous chalk like material, a
sedimentary rock that forms on a sea floor or lake bottoms. It's a form of
opaline silica, microscopic plants secrete silica to form hard shells of opal.
Diatomite is a common filler in paint and paper.
FLUORITE
Fluorite is crystal of calcium fluoride, found in veins with the metallic ores of lead and silver, or with barite, gypsum, calestite and dolomite, or by itself.
Fluorite forms a full color wheel, it's the only non-metallic element that
has this capability. There's also a luminescence fluorite which emits a visible
light when crushed, heated or radiated. England mines "Blue John" which was
carved into bowls, cups and vases. The Chinese mined a green variety and carved
statues.
BARITE
Barite is crystal of barium sulfate, called heavy spar, it has no coloring
power by itself. Barite is a non-metallic mineral crystal mined in England,
filling the cavities in limestone. As barium it's an extender in lead based,
cadmium paints and vat dyes
CELESTITE
Celestite is strontium sulfate, the ore of strontium. This strontium
element supplies "the rockets red glare".
HALITE
Halite is sodium chloride, rock salt.
LAKE MINERALS
Borax is found in dry lakes as in Tibet, it was called "tin-cal", a
Chinese word. Boron is also found in boric acid and in the mineral sassolite,
mined in Tuscany, Italy. It can be found in a mineral called tincalconite and
ten others. Borax and shellac form the paint called "water shellac". Boron
hardens metals, and makes soaps and medicine. Molten borax will dissolve
insoluble metal oxides and is the flux for soldering, brazing and welding
metals.
TRONA
Trona is soda ash in its hydrous state as in sodium carbonate. In its
anhydrous state, it's soda ash. 1/5 soda ash and 4/5's sand quartz, make glass,
with enough heat.
SODALITE
Sodalite is sodium aluminum silicate with sodium chloride, it forms in
massive crystals, like over an acre!
SULFUR is abundant in gypsum and as an anhydrite from sea water, it is also found in limestone to some extent. Sulfur was used as an insecticide in 1000 B/C, ancient Greece gathered it in Delphi, from a deep crevice exuding sulfurous gases from Mount Parnassus. Sulfur burns a blue flame and emits sulfur dioxide gas.
SULFURIC ACID is sodium carbonate and is used in making glass. It was once called "oil of vitriol", a di-basic acid of sulfur made from sulfur tri-oxide. To "vitriolize", means to treat with sulfuric acid, it gives a glassy appearance to metallic sulfates; white vitriol is made from the lead or zinc ore, blue vitriol is made from copper, green vitriol is made from copperas, a ferrous sulfate, iron.
SULFIDE contains the free radical or more electropositive element, it effects changes with other ores.
SULFATE, to treat with a salt of sulfuric acid will make a sulfate. Lead sulfate compounds form on lead, you "sulfatize" when you roast galena, the lead ore that contains sulfur.
SULFUROUS ACID is dissolved sulfur di-oxide gas in water, to form salts called sulfites.
SULFITE is the salt of sulfurous acid which makes the cadmium sulfides
from yellow to red. Arsenic sulfides are yellow-green, yellow, orange and
red. Copper sulfides are green to blue. Lead sulfides range from white to red.
Note: Oil coal-tar colors go from hansa yellow to ultramarine blue moving
around the magenta side.
CEMENT
CEMENT, like in Portland Cement, is made of lime, from heated gypsum, sand and alumina which is the oxide of aluminum present in clay. That makes cement hydraulic, the clay absorbs water and the cement sets quickly, too quickly for mural work. Heated gypsum burns off sulfur as it becomes lime, any traces left behind would also be bad for a mural's pigments. So don't use gypsum lime for murals, use limestone lime. Soak, or slake the lime from six months to twenty years, the longer the better and add 3 sand to 1 lime to make cement. Use a fine sand or marble powder for the last coats, three coats are better than one and six coats are better than three.
CEMENT FONDU is a cement with a high aluminum content,
KEENE CEMENT has alum salts added and makes a very hard mass.
CASEIN CEMENT, casein added to cement makes it harder and set faster.
HIDE GLUE CEMENT, Add less then one percent hide glue into the cement to slow setting from ten minutes to two hours.
OXYCHLORIDE CEMENT is also called , PLASTIC MAGNESIA. It's calcined magnesite, it's calcined just short of becoming magnesia [as limestone becomes lime], and made into cement with a strong solution of magnesium chloride. This is CAST STONE.
STANDARD COLORS IN CRYSTAL MINERAL COMPOUNDS,
CRYSTAL TERMS
ALLOCHROMATIC, is an element coloring term meaning an outside element is included in the compound.
ANISOTROPIC, Crystals in which light travels at different velocities in different directions.
AMORPHOUS, without crystalline structure, like the opal or glass.
CLEAVAGE, a breaking point along a face, variable.
CUBIC SYSTEM, four pyramids or tetrahedrites block together and make a cube, this system has the highest symmetry, the triclinic has the lowest. The other systems are Tetragonal, Orthohombic, Trigonal, Hexagonal, and Monoclinic.
HABIT, is the shape of a crystal. There are seven systems, and thirty two classes within the systems.
PARTING, similar to cleavage but along the twinning axis.
PSEUDOMORPHS, A crystal inside a rock may change it's chemical composition and still keep its original shape, common to quartz.
FRACTURE, broken.
AGGREGATE, A mineral without an obvious crystal shape, crystals forming masses as gold and silver [dendritic], tree or plant like, or the kidney-shaped hematite [reniform].
COMPOUNDS, Two or more elements form compounds. Oxide compounds are combined with oxygen and a metal element, hydroxides, carbonates, silicates, sulfides, sulfates, arsenides, antimonides, Tungstates, and chromates are all compounds.
CARBONATES, carbon compounds.
GANGUE, other minerals found with the mined ore.
GOSSAN, The "iron hat" of gangue minerals with iron and manganese oxides, the soluble minerals sink lower in the earth to form azurite, malachite, and cuprite. Sulfur sinks still lower and forms sulfides like chalcocite.
HALIDES, contain halogens, negative elements, fluorine, chlorine, iodine and astatine.
NATIVE, Uncombined with other elements, natural.
OXIDES, a mineral combined with oxygen as the sole anion. These are usually hard because of close packing.
HYDROXIDES, have the complex anion [OH].
PSEUDOMORPHS, A crystal inside a rock may change it's chemical composition and still keep its original shape, common to quartz.
SILICATES, Silicon combined with oxygen, SiO4.
STREAK, The color left behind from an abraded (usually rubbed on frosted glass to test) mineral.
SULFIDES or SULPHIDES, Metallic ores formed in the presence of sulfur and the absence of oxygen, C032-.
TENOR, The metal content of an ore.
ANTIMONY
ANTIMONY native is Naples yellow, a very early pigment replenished in the
Vesuvius eruption of 79 A/D. Antimony oxide was made artificially since
the early eleventh century. Antimony sulfides are found in the mineral galance
stibnite, in Italy and Human, China.
ARSENIC
ARSENIC, Arsenopyrite is arsenic's main ore. Arsenic disulfides are red
realgar and yellow orpiment, both were used in the early Egyptian days in
paint.
COPPER
COPPER ORE native, is brittle unless it's heated (annealed) as the ancient Anatolias did in 6000 B/C. The ancient Eskimos ground fish hooks out of this native copper. Copper pitch ore was used all through the Neolithic Period.
CUPRITE is a cubic transparent ruby-red crystal, formed as a secondary mineral from exposed copper ore. TENORITE is black copper oxide.
CHALCOCITE is another secondary mineral of copper, found in metallic sulfides, precipitating in still waters as a soluble sediment.
CHALCANTHITE is retrieved from the chalcocite sediment, this is the basis of the ancient blue vitriol, and it made blue and green frit. Notice, it's the complementary color of cuprite. I'll point this out in color wheel oppositions.
ANTLERITE is copper's chief ore mineral, it's a copper sulfate.
CHALCOPYRITE is the primary ore formed in quartz.
CHRYSOCOLLA has a hardness of 2.5, it's a light cyan colored ore that the Egyptians wore as jewelry, they matched this color with copper and tin glass frit. Small scarabs were found glazed and considered as good luck pieces, it was a sample of the color pigment they sold on the ancient world market.
MALACHITE is a secondary mineral ore of copper carbonate, a native green pigment when crushed.
AZURITE is another hydrated salt of copper carbonate, this one's a deep cyan color which looks blue, it was also used as a pigment all throughout the ancient years, it was transparent to opaque. Soak azurite long enough and it will turn green, ammonia turns copper blue.
ACETATE is a salt by acetic acid or vinegar. A hydrated copper acetate was said to be the first artificial color, I made some and it was cyan on the green side. It was made by the Romans in 1000 B/C and was called vertigris. They would have had to suspend Egypt's chalcocite sediment in vinegar to precipitate a salt. Egypt had murals of wine harvests 2500 years earlier. I suspect Egypt made it first, before Rome, since they did so much with copper.
PHTHALOCYANINE is copper with one of it's atoms removed to make a
non-metallic pigment. This pigment doesn't react to sulfur as metallic copper
does, it is transparent and covers the colors from yellow-green to cyan. This is
perhaps the most important color ever discovered.
IRON
GOETHITE is iron hydroxide crystals found yellow to brown in earthy masses, it's an ore of iron that contains the natural yellow ferric oxide pigments.
IRON OXIDE ranges from white calcite, yellow, yellow ocher, sienna, red oxide, brown and green umber to black. Adding heat [calcine], brings out the red side and adds a transparent quality if silicates are involved, as in sienna. Magnesium is the purple side of caput mortuum, present in iron.
HEMATITE is iron ore, heat it to 1830 degrees and get iron. Hematite naturally crushed and oxidized leaves a red streak powder that was the stone-age red and Egyptian rouge.
PYRITE is iron sulfide and sulfuric acid, dissolved in water to leave behind limonite. Fifty four percent of pyrite is sulfur, decomposed pyrite is hydrated iron oxide.
LIMONITE is a secondary ore of iron that forms yellow to brown oxides. This is the second bit of proof that yellow and brown are the same color (Tint to shade) in my color wheel, CENTERING COLORS.
SIDERITE is iron carbonate, going from yellow to brown.
CALCITE is a native iron pigment mineral that is white. Iron will make all colors.
CALADONITE is a green earth iron silicate mineral.
LEAD
GALENITE or GALENA. Galena is lead sulfide mineral, native, and it contains sulfur. Roasting the galena ore produces a basic lead carbonate, white lead sulfate. Also formed is a water soluble salt compound of lead arsenate.
CERUSSITE is a native lead carbonate mineral, white lead.
VANADINITE washes to lead vanadate, a red-orange crystal.
WULFENITE is a transparent orange crystal.
LEAD ACETATE is a colorless crystal formed by acetic acid touching lead, it is water soluble and called sugar of lead. Lead acetate can be used as a siccative.
LEAD IS CORRODED with fumes of acetate and carbonic acid in steam. It forms a white lead sulfide or oxidized white lead and contains the free-radical that effects so many pigments. This is artificial basic lead carbonate, our white pigment. Hydrogen peroxide will stabilize and remove the free-radical, turning lead sulfide to lead sulfate, a stable white lead.
LEAD CARBONATE is formed by mixing in solution, lye and carbonic acid with
lead acetate. It's the whitest lead but not as opaque as white lead
oxide.
MERCURY
CINNABAR is the ore of mercury, mercuric sulfide, the red crushed ore is
the color vermilion. Cinnabar is found in crystal and masses in South
Central Spain and in China. China did more carving in it than painting with it.
The rest of the world found it a very useful pigment. The Carthaginians
and the Romans both worked the Spanish mines for cinnabar.
TIN
TIN ORE is found in cassiterite, a tin dioxide, the principle ore of tin, along with wood tin. The symbol for tin is Sn, for stannum.
Tin ore is found in rock forming minerals like feldspar, quartz and mica. First, tin was exposed on cliff faces, where the rocks eroded exposing the veins. Eventually it entered streams and rivers to be stream mined. Tin was mined in Eastern Greece, ancient Anatolia, Upper Syria, the Tigris Euphrates Valley, Afghanistan, the Mekong River and England. Egypt's paints were tin based.
TIN OXIDE is black and fires white, mix tin oxide and cobalt oxide with
heat and you get cerulean blue. You can get a similar blue by mixing and
firing tin and copper chalcanthite with quartz sand like the Egyptians did, this
made their highly prized frit colors, which they traded through the
Phoenician's, ancient-world-wide. Smelt tin ore and copper ore and you'll get
bronze. Bronze is the metal the Egyptians made their saws out of to cut
the limestone for their great pyramids.
ZINC
ZINC: The zinc primary sulfide mineral is water soluble, and is often found with galena.
ZINC SILIATE: Zinc silicate comes in a variety of colors, transparent yellow and green, opaque white, yellow, green, red, brown and black. All these colors were found in the Franklin Mines of New Jersey, 22 miles from where I was born.
ZINC OXIDE: Zinc oxide is called zincite and is colored white, yellow, orange and red.

B/C PIGMENT PALETTE
Here's the mineral palette back when
Sandraca (sandracca)was King and Zeus had a son named Castor. Castor is also the
brightest star in Gemini. Castor oil was added to sandaraca (sandracca) about
2000 B/C, to soften, extend and make it pliable. Sandaraca was a major medium
into the A/D's, when mastic, wax, egg, and oil started replacing it.

transparent yellow was brought to England from India, where it had been used as
a pigment for as long as India had cows. The raw product is called Monghyr,
magnesium euxanthate natural organic, after a city in Bangal. England made this
in oil and kept it's ingredients a secret for eighty years. It was in brown to
yellow and orange to yellow, two dual-toned colors.
Artists' Pigments, A Handbook of their History and Characteristics, by Robert
L Feller, National Gallery of Art, Washington. 3.5 Chemical Properties
"The glucuronic acid portion of the molecule confers upon it considerable water
solubility; the euxanthone portion permits compatibility with oily media.
3.6 Oil Absorption and Grinding Qualities The oil absorption given by Doerner
(1939) is up to 100% 4.1 Chemical Composition The principal constituent of
Indian yellow is a mixture of the calcium and magnesium salts of euxanthic
acid.

COPPER. Verdigris, hydrated copper acetate crystals, water or resin soluble. This color is usually listed under green, [vert] meaning green. Since this was the first artificial color made by the Romans, I made some. Using materials I knew they had I put copper in ammonia, this turned the ammonia blue, a few drops of acetate acid [vinegar] and the color changed, it precipitated a light cyan-green salt. Mixing the salt with damar, I painted with it, and, well it does go a little farther, I mixed the salts in sulfuric acid and it turned clear. I was stirring the mix with my steel palette knife and it put a copper plating on it! I wonder if the Romans ever rust proofed any of their iron. I remember reading once, that at an Egyptian excavation they found some clay pots with holes in them for wires, the archaeologists thought they were using them as storage batteries for plating, I believe it.
MANGANESE. Manganese also makes a cyan hue, I don't know when it was first used, but it was sold as a liquid in a blatter.

RED, Cochineal, ground female "coccus cacti" insect, originally from Central America, imported to Morocco. Soluble in ammonia. The coloring matter is carminic acid, an anthraquinone derivative.
Karmes Scarlet is the oldest Magenta color, made from an insect found on the oak tree, it secrets an alcohol based lac and is found all over Europe.
Madder root from the "rubia tinctoria" from red to magenta to brown. Found from Anatolia to Persia. India and China use the "rubia cordifolia", which is a cooler magenta color. India exported madder, indigo, weld and Indian Yellow. The three primaries plus an ultramarine blue color.
Brazilwood, named the country, its color is clear in wood and boiling it makes a magenta dye, to dye red, you add a tin mordant, Brazilwood dye comes from the local "caesalpinia" tree, Logwood, from the "haematoxylon" tree makes hematin, boiled, it turns violet to blue-black.
BLUE, CYAN, Indigo, Grown in India, the "Indiagofera tinctoria" thrives in the tropical climate, the active ingredient is found in the leaves, an indol derivative is fermented from a sugar, this precipitation is insoluble in water. Alkalis dissolve it and form the sodium salt indigo white, which oxidizes into many shades of blue. Aniline blue has the same chemical composition and replaced it in 1870. This blue was the most important color in Chinese rugs.

Here are some permanent chemical pigments used in oil and acrylic paints
today.
Golden Artist Colors, New.. On 6-10-06 I received a welcomed new color from Golden. Indian Yellow Hue, made with Arylide Yellow PY7, Nickel Complex Azo PY150 and Quinacridone PR206. This is good Golden Indian yellow Hue. Also a Brown/side Indian Yellow called Nickel Complex Azo, plus an Indian yellow Hue green/side Nickel Azo Yellow, PY150, PG36, PY3.
In the printed copy describing this new Historical Fluid Acrylic Color I was happy to see my information which was first put on the internet in 1996 regarding original Indian yellow. My print research turned up the cow urine history of this very important color and this information started spreading in 2002 and Indian yellow hue started appearing. The internet loves information and Golden used it describing their new Indian Yellow Hue on their Historical Fluid Color Chart.
NEW. 2006, Golden Acrylic is the first acrylic manufacture to
include all three transparent primary colors, Two transparent yellows, the
golden side called Indian Yellow Hue, Arylide Yellow PY7, Nickel Complex Azo
PY150 and Quinacridone PR206 and the brown side called Nickel Yellow Azo PY150
same hue as PY153. A Phathlo blue PB15 (cyan) and a quinacridone magenta PR122.
Nice going Golden!

CHROMIUM- Element, metallic, occurring in compounds to make pigments, a hardening element as with chromium steel. Chromium compounds are chromic acid and it's salts, called chromates. First the metallic and acid name, followed by [ATE], sodium sulfate. This is the salt of sulfuric acid and a sodium compound. The salt of acid with fewer atoms to the molecule, ends in [ITE], sodium sulfite, the sodium salt of sulfurous acid. [IC] and [OUS] designate numerical variations in an acid or oxide, [OUS] being smaller and more unstable, these that don't contain their maximum complement of atoms are called unstable. [THIO] means sulfur-bearing, [AZO] means nitrogen-bearing,
CHROME- The adverb for chromium, chrome yellow is composed of chromates of lead, barium, or zinc, Chrome green is made from chromic oxide, chrome red is a basic chromate of lead.

CHROMOPHORE- Any chemical group which produces color in a compound as the azo group -N=N-, the structural layout of atoms which is found in many colored compounds.
COMPLIMENTARY COLORS- A color and it's opposite on the "real color wheel" will combine to a neutral dark on the pigment color wheel and white on the light color wheel. To find the complimentary by eye use your color reversing image retention. Look at the color swatch in a bright light for 5 seconds, than switch to a blank white paper. The reversed color will appear.
COMPOUNDS- Composed of two or more elements or ingredients. Binary compounds consist of two elements, first named is the metallic or electrically positive, followed by the negative, which ends in [IDE], sodium sulfide is a binary compound of sodium and sulfur, zinc oxide is zinc and oxygen.
CRYSTALLIZATION- with water, as the blue transparent crystals of copper sulfate contain seven molecules of water to each molecule of salt. Without the water it's an anhydrous white powder.

Molecules of red iron oxide are; Fe2, O3, Fe = iron, O = Oxygen, 2 equals two iron atoms, 3 equals three oxygen atoms. Synthetic resins rearrange the molecules.
RADICALS- Two or more elements hook valences together and act as a single element in a reaction, as [HO] is hydroxyl.
SALTS- Salts are neither acid or base, but they could have those reactions. Salts are produced by action on metal or another salt, or by the neutralizing reaction of an acid or base.
Sodium chloride is table salt, it's soluble, inert and neutral, some salts are active. Barium salt is insoluble. Some pigment salts are made by mixing two solution salts together, forming two new products [called double decomposition], one will remain soluble, the other precipitates as a powder, as some pigments do.
Salts of metals categorize themselves in color, nickel is green, copper is blue, cobalt is rose and anhydrous blue, chromium is yellow to dark red and iron is from yellow and red to brown. This note is taken in my color theory of rim and centering colors in elements.
Normal salt of acid is named for the metal then the acid, ending in [ATE]. Sodium sulfate Na2 SO4 is sodium salt of sulfuric acid, combined. The salt of acid with fewer atoms to the molecule ends with [ITE], sodium sulfite NA2 SO3. Unstable or unsaturated acids and salts have open hooks and end in [OUS]. Ferrous [iron] oxides are exceptions, these are called "loose linkages".

ORE'S COLOR REACTIONS TO EACH OTHER
ANTIMONY
ANTIMONY isNaples yellow, Antimony oxide
white, is Timonox, a British trademark, 1920. It reacts less than lead white
with sulfur, has none of the drawbacks of zinc and would give titanium the best
run for the money, plus, we would still have Naples yellow, a very dense yellow
to light skin color the portraitist used as a base instead of white. If we had a
union we would bring antimony back along with Indian yellow, brown side and
orange side.
ARSENIC
ARSENIC native yellow is orpiment, a sulphide of
arsenic. Native red arsenic is realgar, an arsenic di-sulphide. These are
ancient colors not available today, the best crystals looked clear and
transparent to me. Arsenic tri-sulfide is made today if you can find it.
COBALT
COBALT turns black with sulfur.
COBALT Oxide is black, calcinated it becomes cobalt blue, fired in potash glass it becomes smalt, a popular early Roman color.
COBALT blue today is a mixture of cobalt oxide, aluminum oxide and titanium white, not the same color and not really necessary to the palette. When a color can be mixed using two pigments, you don't need it, but it could be handy as in the brighter Ultramarine Blue.
COBALT violet is a very important cool magenta, [cobaltous phosphate] by Bocour, New York, is the best I've ever seen, there is also a German cobalt violet dark, [cobaltous oxide arsenate] if they still make it.
COBALT salts with potassium nitrite make the color aureolin yellow.
COPPER AS PIGMENT
COPPER turns lead, zinc lithopone [zinc sulfide on barite] and mercury, black.
COPPER is turned blue by alkalis like ammonia, the color is precipitated from the ammonia with acetic acid, vinegar. This makes the ancient Roman color, verdigris.
COPPER turns black with sulfur.
COPPER ARSENATE is emerald green, the most poisonous of all colors.
COPPER CARBONATE BASIC is malachite green native and azurite blue native. Native colors are usually unaffected by anything at all, they are inert.
COPPER non-metallic phthalocyanine cyan to green should replace all other
copper colors, they are inert and safe to use.
IRON
IRON RESISTS LYES, SULFUR AND ACIDS AND MAKES THE MOST COMPLETE COLOR WHEEL OF ALL THE ELEMENTS, BY ITSELF.
IRON is ferric oxide, iron and the gas cyanogen make ferrocyanide, a salt of ammonium ferrocyanide, makes Prussian blue.
IRON hydroxide's are the yellow to brown ochers, based in clay.
IRON oxides are the calcined yellow to brown ochers, turned into red
ochers or red earths, even higher heat would bring up the violets, until
finally, caput mortuum, a purple brown. Raw sienna is an iron hydroxide, burnt
sienna has been calcined, higher heat would make a vermilion transparent because
of the high silicic acid content in the clay.
LEAD SOAPS TURN YELLOW IN OIL, POPPY OIL IS THE LEAST YELLOWING BUT THE SLOWEST DRYING OF THE DRYING OILS, WALNUT OIL IS NEXT, THAN LINSEED OIL.
LEAD sponificates or turns clear in oil, apply lead thickly in the last coats or with age you will see through it to a lower color. Today's lead white is much thinner and slower drying than in the old days.
LEAD has a free radical atom that will leave the lead and turn some colors black, this is white lead sulfide. Hydrogen peroxide will stabilize and remove the free radical, turning white lead sulfide into white lead sulfate, a stable white. Roasting lead ore, glance, will also produce basic lead sulfate, like the ancients did.
LEAD will turn black with hydrogen sulfide, and permanently yellow with heat. Like the ancient massicot yellow, and King's yellow. It will also heat to orange and red. The red lead is the fastest drier.
LEAD can not be used in fresco, the lye turns white lead brown, permanently. Nor can it be used in water colors or pastel, the sulfur in the air will turn it dark.
LEAD is very poisonous, Titanium white is the all around better color, with zinc white a close second, but it is too brittle. Combine lead and zinc and you get the best of both.
LEAD turns these colors [metals] black; tin, copper, cadmium's [they are
sulfur colors], ocher's and earth's if poorly washed will also contain iron
sulfates, Nickel yellow and nickel Naples yellow, they don't seem to make
antimony Naples yellow any more, Arsenic will also turn black.
MANGANESE
MANGANESE native black oxide, manganese
carbonate white, manganese green, blue and violet are all good dryers.
MERCURY
MERCURY and sulfur make vermilion, the natural pigment cinnabar is no longer available, today's synthetic vermilion's doesn't contain either element, so there safe to use in any combination.
MERCURY, basic sulfate of mercury is bright yellow and turns black with
sulfur and copper.
SULFUR
SULFUR will turn all lead colors
black, also tin, copper, cobalt, cadmium's, manganese, arsenic and antimony.
TIN oxides turn lead black, it works with all other metals.
TIN oxides are black, by calcination they become white, tin oxide [stannous chloride] plus cobalt oxide [cobalt sulfate] fired together become cerulean blue, tin and copper fired together become an even cleaner cyan tint, like the Egyptian frit.
TIN chromate [stannic] is yellow mineral
lake.
ZINC oxide white covers less well then lead white, but does not yellow as lead does. It works well in water color. Hydrogen sulfide reacts to make a different white, zinc sulfide from zinc oxide, there both good, Zinc can be made yellow, orange or red.
ZINC does not work with fresco or tempera emulsions, lyes and acetic acid effect it.
ZINC white and sulfuric acid make white vitriol transparent.
ZINC fades Prussian blue, cadmium yellow, cobalt yellow and coal-tar
pigments when used in water colors and gouache.
COLOR CRYSTAL, ORE AND MINERAL CHEMISTRY GLOSSARY
DEFINITIONS, TERMS, GLOSSARY
ATOM, smallest particle of an element with all it's properties.
ATOMS, are measured in Nanometers, [1nm = 10m[-]9th].
ATOM CENTER, the nucleus is occupied by protons and neutrons of similar mass. This is the mass of the atom, the volume is made by the cloud of electrons.
PROTONS, have a positive charge, the number of protons equal the atomic number, hydrogen has one proton.
NEUTRONS, have no charge.
ELECTRONS, have a negative charge orbiting the nucleus, electrons and protons are equal in quantity, so there equal in [+-] charges.
ATOMIC NUMBER, the quantity of protons in the nucleus.
ATOMIC WEIGHT, is comparing the atoms of each element to the hydrogen atom.
ISOTOPES, the neutron quantity changes the atomic weight of atoms with similar atomic numbers, so each element has isotopes and different atomic weights, all based on the weight of one carbon isotope.
SHELLS, electrons orbit on seven tracts or shells, lettered K to Q outward from the nucleus. Each shell has a limit to the number of electrons in it, 2 for K, 32 for Q. Hydrogen has one nuclear proton and one electron in K shell, Lithium, with three protons, has a full K shell and one electron in the L shell.
INERT GASES, will not combine with other elements, they have 8 electrons in Q shell, other elements are considered stable if they can attain a similar outer shell content. Atoms trade electrons with other atoms so their electron cloud can become identical with inert gases, the nearest inert gas.
IONS, This trading leads to atoms becoming electrically charged and known as ions, gain an electron, gain a negative charge. Lose an electron and gain a positive charge, remember, electrons are negative.
ANIONS, are negatively charged ions, they have gained one [-] electron.
CATIONS, are positively charged ions, they have lost one [-] electron.
VALENCE, the "hook" to hold another "hook", hydrogen has a valence of one, it can hook up with another atom with one valence. Valence is the chemical binding power +/-.
VALENCY, the process of gaining or losing electrons. [Na] sodium, has one more electron than the nearest inert gas, neon [Ne], it's written Na+ to show it's a cation. Fluorine [F] has one less and is written F, meaning it's anion. Valency is the number of electrons an atom will gain or lose to attain the configuration of the most similar inert gas.
MONO VALENT, ions Na+ and F- are both charged by one electron off being stable and inert.
DIVALENT, magnesium has two more electrons than neon, the closest inert gas. By losing both it becomes a divalent cation, written Mg2+.
ATOMIC STRUCTURE, [C] carbon and [Si] silicon have atomic structures midway between two inert gases. Carbon can either gain four electrons to become C4- and resemble neon or lose four electrons to become C4+ resembling helium.
REPULSION, The electrical charge of protons keeps other protons away by mutual repulsion, they have similar spinning directions. When two atoms link, the interaction is by the outermost electrons. There's three ways to do this.
IONIC BONDING, is two elements forming ions of equal and opposite valency, the spare electron of one atom separate to fill a vacancy in the outer shell of another atom. The pair of ions are held together electrically. Groups of ions can be linked this way, a divalent cation can link with two univalent anions.
COVALENT BONDING, shares electrons, two or more atoms coming close together share, and both or all, have eight in their outer shell. Solids containing ionic or covalent bonds are rigid.
METALLIC BOND, metals pack the ions closely together and leave the outermost electrons free to move independently. This lets them be hammered thin, form wire and conduct electricity.
COMPOUNDS. When the linked atoms are of different elements, the result is a chemical compound.
COMPLEX, more than one compound.
COMPLEX IONS. In many minerals, subgroups of atoms are bonded in a covalent way forming complex ions or radicals. A common example is the tetrahedral arrangement of four oxygen atoms around a single silicon atom, to give a complex anion, written [SiO4]4-.
ELECTRICALLY BALANCED COMPOUND, the complex anion [SiO4]4- must be bonded to a cation or cations with a total valency of four, to get an electrically balanced compound. Two atoms of the divalent metal Mg would fit and the mineral forsterite has the composition [Mg2]4+[SiO4]4-, or it could be written Mg2[Si04]4-.
MOLECULES. Heating a mineral causes the atoms to vibrate faster, breaking the bonds between them. In this way the independent groups in steam, called molecules, move freely. Share electrons, be a molecule.
AMORPHOUS. Substances that do not have the atomic order of crystals are amorphous, they don't have the directional properties of crystal. Opal, natural glass, and flint are amorphous aggregates.
ION SHAPE. Crystals are made up of ions having the shape of spheres, these fit together leaving a space in the center. Three oranges and a pea. The carbonate ion has this shape, a pyramid with three sides and a bottom. The common complex ion [CO3]2- is carbonate.
TETRAHEDRON. Four oranges and a grape would make a Tetrahedron, the shape of the silicate anion [SiO4]4-.
OCTAHEDRON, is two pyramids joined base to base.
CUBES, have all equal sized ions, four polyhedra pyramids equal a cube, as in coordination polyhedra and close packing.
POLYMORPHS, are the structures possible by a compound, Si02 makes five different structures. Diamond and graphite are polymorphs of carbon, graphite is two dimensional, flat and weak. The diamond is a three dimensional latrahedrally-oriented covalent bond, strong and possibly twinned.

COLOR WHEEL IN ELEMENTS AND CRYSTAL
Light is a painters element, it has shape when it is confined and it's intensity and mass can be measured. Full sunlight's weight is equal to the weight of a single grape, spread out over an entire football field, and that is constant weight. This light reflects off the primary and compounded elements we see around us. Permanent pigments are made of these elements, either organic, inorganic or synthetic. Each element, in it's natural and calcined state is capable of making and reflecting only a select portion of the color wheel. It also has painting characteristics unlike any other element, so if you like a pigment for its characteristics, it cannot be replaced.
Three examples are; 1, lead, no other element dries as fast or is as opaque. 2, Cobalt natural, (cobalt aluminate blue spinel is just another pre-made color for you to buy), and 3, antimony Naples yellow, probably the artist's most favored color before Ostwald and the ASTM's intervention. They matched the dried color with new cheaper elements without regard to its natural characteristics. Rubins would have had them flogged if they tried that while he was alive. Today there just aren't enough artists that know about the differences. We need a paint manufacture that cares!
So, simplifying your choices is the name of the game here, what colors and what characteristics are most needed to complete a full color painting. Use the transparent pigments that are available and be selective in choosing the opaque ones.
There are twelve to thirty six colors in my basic color wheels, it's mine because no one else ever put it in print in this order, I want it to be yours. This is original concept work here.
I start with yellow at the top and "Read Red Right," the three R's of color. Play the wheel like a typewriter. There are only twelve colors to remember, forward, backward and centering across the middle. Across the middle is what makes the Real Color Wheel different from all the rest. It matches the pigment color wheel with the RGB/YMCR color wheels so they both work at there best.
In a twelve color wheel, Yellow is represented by "Y," Magenta by "M," and
Cyan "C." A pure unadulterated yellow would be YYYY, half yellow and half
magenta would be YYMM, or the color red, each color has four characters. Orange
is YYYM. Scarlet-crimson is YMMM. The sixth color away from any color is halfway
around a twelve-color wheel making it the opposite, or the complementary color.
The opposite of YYYY is MMCC, Ultramarine Blue.
HERE ARE THE SYMBOLS OF ALL TWELVE SUBTRACTIVE PIGMENT COLORS
YYYY=Yellow, YYYM=Orange, YYMM=Red, YMMM=Scarlet-Crimson, MMMM=Magenta,
MMMC=Purple, MMCC=Ultramarine, MCCC=Azure, CCCC=Cyan, CCCY=Turquoise,
CCYY=Green, CYYY=Yellow-green.
There is no pre-made transparent pigment paint for the color MCCC, Azure, Cobalt Blue is a close color but opaque. It matches the ancient color of Azurite. Cu3[C03]2[0H]2, a copper idiochromatic color. Azure can easily be made with copper phthalocyanine blue and a good ultramarine blue or a little cobalt violet [magenta]. In fact with a cobalt violet, [the cool magenta], you won't need ultramarine blue, you can make it. One way or the other, Azure is a beautiful color that nature uses often.
Each element can only make its own range and texture of colors. No other element has its similar unique capabilities. Modifying the element can make its opposite or complementary color, as the cuprite crystal of copper and the sediment of copper do naturally.
By explaining minerals and crystals, and the elements that make and color them, you will understand the real color wheel and know the pigments that make it go 'round. This color wheel joins the pigment and the light color wheel together as one, and agrees with the nature of your eyes "afterimage."
To make the light color wheel match the pigment color wheel, replace
Yellow's neutral dark (which has a Green tinge, with Burnt Umber), (that's the
Red's normal dark). Than change Cyan's centering dark to Ultramarine Blues dark.
Now all the colors in both palettes will have working oppositions.
CRYSTALS, LIGHT AND COLOR TERMS
ALEXANDRITE EFFECT, The chrysoberyl alexandrite is red in candle light and green in daylight.
ALLOCHROMATIC, minerals colored by a foreign element are called allochromatic. Ruby is an aluminum oxide colored by chromium, so it's allochromatic foreign and not written in the symbol AL203.
IDIOCHROMATIC, minerals colored by elements which are a regular part of the chemical composition. The peridot crystal is in the olivine category, it's magnesium, iron, silicate. The green comes from iron, making this an idiochromatic home color [not foreign] crystal.
ANALOGOUS, colors are side by side on the color wheel rim.
INCIDENT ANGLE, lights entering angle.
REFRACTIVE INDEX, when light enters a cube or amorphous structure the incident ray is slowed by the atoms inside. The ratio of the speed of light in a vacuum compared to the speed in the structure is called the refractive index. In crystals other than the cube, the light splits in different directions at different speeds.
REFRACTION, The deviation of a ray of light upon entering a transparent medium, is refraction away from the normal. The emerging ray is separated into the colors of the spectrum. Red refracts most, violet and magenta the least.
DOUBLE REFRACTION, an incident ray enters and splits, each ray traveling at a different speed.
DISPERSION, diamonds, glass and water give dispersion of light with the proper incident and reflecting angles, thus splitting up white light into its spectrum colors. The water droplets in a rainbow are at the proper angle of refraction to give each color seen by you. Each person sees their own rainbow. The axis from the sun through your eye to the center of the rainbow's circle is the basis for the angle of an incidence you see as the rainbow's refracted light. Any medium in which the high-frequency light travels more slowly than the lower frequencies are called dispersive.
DIFFRACTION, diffraction is light bending around the edges of a mass.
ISOTROPIC, crystals in which light travels in all directions at the same velocity.
INTERFERENCE COLORS, a thin film of soap or oil will change the direction of the incident ray laterally and cause the prism effect, as the thickness changes the color's change.
LUMINESCENCE or FLUORESCENCE, is stimulated by radiation.
PHOSPHORESCENCE, persisting luminescence after stimulation.
PLEOCHROISM, the change of color when viewed from different
directions.
CRYSTAL CHROMATE [COLOR] ELEMENTS
THERE ARE 92 NATURAL ELEMENTS. EIGHT ELEMENTS MAKE UP 99% OF THE EARTH'S CRUST.
On the ELEMENT PERIODIC TABLE, #22 through #30 are the coloring elements that give color to crystal compounds. Elements color in harmonies. Analogous, is side by side around the rim of the color wheel. Centering, means moving from the high chroma rim to the center's natural dark position. Complementary colors are opposite colors, 180 degrees apart, triadic colors form an equilateral triangle, they're 120 degrees between colors. Split-complementary colors are on each side of the opposite color, making a "Y".
