The most suitable plaster for casts that have to undergo a lot of force from the clamps, as Violin Neck Graft.
It has excellent hardness (Brinell) and very high compressive strength (800 Kg / cm2), greater than any alabaster gypsum.
The models made of extra-hard ceramic plaster guarantee absolute fidelity in the reproduction of details!
