Notice the yellow splotches on #8, even on Naples yellow stand oil shows up yellowed.
Dammar in #1 position is the only one that did not yellow in five years.
The darker spot on #6 is a dense paint test.

#1- Wax and dammar, the easiest to paint with. No gloss.
#2- Stand and turpentine, the turpentine essence evaporates very fast and must be replenished often. High gloss.
#3- Venetian Balsam. High gloss.
#4- Cold pressed Linseed oil. No gloss.
#5- Venetian Balsam and oil, good glaze, use very thin. High gloss.
#6- Stand oil and wax, the end of the stroke breaks off, stand oil would rather stay sticky. Low gloss.
#7- One part paint, two parts wax, a great transparency extender. No gloss.
#8- Three parts Stand oil, one part cold pressed linseed oil, balanced slippery and sticky, smooth. Medium gloss.
