Artists Oil Paint History

Commercial cooking oils: Margarines, buttery spreads, cooking sprays, and oils like canola, soybean (sometimes labeled “vegetable oil”), cottonseed, safflower, grapeseed, rice bran, wheat germ, and corn.

All olive oil contains free fatty acids. To be described as extra virgin, an oil must contain less than one percent of these acids. More than one percent but less than one and a half, and you have a vierge fine. Anything above this, up to 3.3 percent, can only qualify as virgin.”
