Description

Casein paint that is hydrolyzed using ammonia. Ammonium casein is prepared by soaking casein powder in water with Ammonium carbonate. Ammonium casein has a slightly lower pH (8.0-9.0) than Lime casein (9.0-9.9), but it is higher than Borax casein (7.0-7.8). Ammonium casein should be prepared fresh as it may become unstable and separate after a few days (Wehlte 1975).
