Liant à la caséine

Wehlte recommended saponification of casein with borax. This means that the fungicide is already contained in the casein binder. Undiluted, this mixture can be used as a base for casein tempera; as a binder for painting wood or canvas, it should be diluted with 3 parts water. Shelf life: 9 months after production. The 250 ml are packed in a PE dispenser bottle.
