On the other hand, any material when used in a sideless, twin-arch tray must be firm enough to support the burden from the gypsum in the event the model is poured, without sagging less than the load in the stone. It appears that 1 viscosity of material wouldn't be able to Preferably fulfill all these parameters concurrently.
