Lactic Casein is a natural substance extracted from milk. In the first place it contains calcium and phosphoric acid. Lactic Casein was used for the preparation and the realization of icons. Casein is the binder of milk paint.
Casein is still used as a coating, as a glue to rub, as a binder to paint and, it seems, as an adjunct in the manufacture of certain inks as well as wood glue especially in the industry and finally as an ingredient of wood pulp in different sectors of activity.
Casein is also used as a binder for paints: tempera and fresco painting as well as for lime mortars.
This product is appreciated because its reliable behaviour has been well known for millennia.
