Use:

Gradually sprinkle the model plaster with room temperature water until it is wet in the water and sinks. If there is only a little water above the settled gypsum, mix it into a homogeneous mass, making it as little as possible. The mixing time is approx. 1 minute.
Tap the model plaster massage to the table top, knock on the side of the vessel to leave the air bubbles.
The mass thus prepared, depending on the density of the material, is approx. It can be used well for 10-12 minutes, ready for casting.
After a longer period of time, the mass begins to bind, hardens, and for larger mass castings it feels heat, and it warms a bit by hand.
After starting the bond, the material should no longer be used!
