Formula for Cadmiums
This formula is for cadmiums from Kremer Pigments. I have made each of the cadmiums they carry and each one has made with the same formula and does not require stand time or aging.
For a 37 ml tube:
Cadmium pigment- 4 tablespoons
Linseed oil- 1 tablespoon
Grind the pigment dry a bit first on the mulling table.
You can get by with a 3.5:1 ratio if you are trying to save a bit.
