Casein powder

Milk was the first glue used in ancient times, it was added to the plaster, instead of water, to give it greater resistance to bad weather. Casein is a milk clot and comes as a white powder. The grinding process makes it easy to adulterate the product which, although invisible, irremediably alter the quality of the same: for this reason the casein present on the Patina Style shop comes from a supplier that respects my same quality standards. Lactic casein is soluble in basic reaction salts or alkalis, with which a binder for tempera and water resistant paint is obtained which is also called washable paint. .
