Casein Paint with Lime
Yields about 1 quart
1 gallon nonfat milk
2 1/2 ounces “Type S” lime (dry powder available at hardware stores)
2 1/2 cups water
Natural earth pigment (more or less depending on desired color)
6 cups filler (usually whiting)
- Leave milk in a warm place for a few days to curdle. Then pour through a colander lined with cheesecloth. You should have about 2 cups of curds. The whey can be composted.
- Mix curds and lime powder in a blender. Add a little water if the mixture isn’t blending well. Strain to remove any lumps.
- Add water to the binder immediately after it is prepared.
- Dampen and crush pigments. Add them to the mixture a little at a time until desired color intensity is achieved.
- Stir in filler.
