Egg Tempera Caseina (Developmental Egg Yolk/ Casein Binder)

Casein (borax emulsified milk protein) was mixed with chicken egg yolk in a 1;1 volume.
Stirring lead to a stable emulsion. The binder was mixed with tempered ( wet with water) commercial watercolor. The test paint was placed on bristol foundation and dried quickly. The flow off the brush was easily controlled.

We are studying possible microbial fermentation of this paint formulation. We want to determine if the pigment prevents microbe degradation of the paint. We will post our findings.
