Oil? What kind of Oil?
Traditionally this is Linseed (Flaxseed) oil. This is available in a variety of qualities and prices ranging from the high quality very faintly yellow expensive cold pressed Linseed oil to the cheap chemically extracted oil one finds in hardware stores which is deep yellow. Other possible oils that are used in the making of oil paint is poppysead oil (which is nearly colorless) and walnut oil (which dries slower allowing for additional time to blend working wet into wet.
- Linseed Oil – made from flax, linseed is the most popular due to its flexibility and resistance to cracking. It does have a strong tendency to yellow with age, however.
- Walnut Oil, Poppy Oil and Safflower Oil – much less likely to yellow, these thin, clear watery oils are much more prone to cracking.
