A type of Casein paint that is hydrolyzed using Borax. Borax-casein is prepared by soaking Casein powder in water with commercial borax. Borax produces a stable emulsion that is slightly alkaline. Borax casein has a lower pH (7.0-7.8) than Lime casein (9.0-9.9), and Ammonium casein (8.0-9.0). A preservative, such as Phenol or p-chloro metacresol, is often used to eliminate biological growth in the solution.
