So, I have been doing research on making casein paint. Casein is the predominant protein in milk. To make casein paint, you start by making quark, a simple cheese like cottage cheese, made by souring the milk with vinegar. Then you add hydrated lime, which turns it into a glue-like medium. Finally, you add pigments and you have paint!
I ordered a sampler set of French mineral pigments from Earth Pigments. They told me they didn’t have the lime, so I purchased it from a local masonry supply, but had to get a 50-pound bag ($8.99), however, when my pigment order arrived, a 6-oz bag of lime was included (for $2.99 - you do the math.) Yesterday while making other cheeses, Lynette combined the vinegar and fresh milk and set it in a warm spot to make the Quark for me. Today it was successfully curds and whey, The curds are the milk protein pat. I strained out the whey and rinsed the curds with cool water to wash out excess whey.
Vendors cannot ordinarily sell artwork at the Rochester Downtown Farmers Market, but I will be permitted to sell these paintings because they are made from a farm product, our milk. I am curious to find out whether anyone will be interested in purchasing my art at the market!
