Kaupo BromeliadOil on linen panel, 15x22
This painting done with Liquin is in a class by itself, it's fast drying, and a complete medium. Even better is a new product called Galkyd, it's a brand name for alkyd oil pure, 12-12-06. It doesn't require a drier either. I make a medium of it by adding 75% turpentine, It doesn't yellow as much as pure linseed oil. It has draw-backs though; the brush drags and lifts off the paint which is difficult to work with.
I also like my own mix of 4 parts Stand Oil, 2 parts Raw Cold Pressed Linseed Oil, 2 parts Venetian Turpentine, 1 part Turpentine, 1/2 part Wax, 2% Drier.
If you like the way the type color matches the painting,
THE MOST PAINTERLY MEDIUM OF ALL is this, 75% Damar and 25% Beeswax paste. Dissolve the beeswax 1:1, in warm turpentine to make the paste and store it. This medium will not yellow. Add 2% drier and it will be dry in twelve hours. Drier yellows more than oil.
If you want a gloss, use a damar varnish finishing coat. The Romans mixed this medium and pigments to make their "wax cakes" which were like our tube paints, except they could be redissolved with turpentine. This medium is a big loose paint, you can change your work in progress, great for murals. Damar gives wax the smooth slippery stroke and allows a buildup of paint.
