The solubilities of copper in sweet whole raw milk held at a constant temperature for 30 minutes were determined for temperatures ranging from 20 degrees Centegrade to 100 degrees Centegrade. Copper sheets of known dimension were totally immersed and agitated in milk for 30 minutes at the specified temperature. Solubility values were determined by difference in weight of the copper sheets and also by determining colorimetrically with potassium ethyl xanthate the copper present in the ash of the milk. Solubilities per unit area increase with rise in temperature up to 80 degrees Centegrade.
