Lactic casein occurs as a straw-colored powder that is sparingly soluble in water. Instead, it is soluble in basic-reacting salts or alkalis, with which it makes:
Ammonium Caseinate, used as a binder for wall paints (or on other substrates) and for the consolidation of the paint film.
Calcium Caseinate, a very tough glue with strong adhesive power that is irreversible after a short time and resistant to water.
In violin making, it is used for glue preparation (see below in details) or as a protein insulator, ground.
The dilution ratio in latter case is around 1 : 20 a concentration by weight around 5 percent dry matter.

Nota: Nelle preparazioni può essere utile scaldare leggermente l’acqua; non si deve però mai riscaldare sopra gli 80°C, temperatura alla quale inizia a formarsi un coagulo.
