Question

Accepted Answer

The purity percentage of gypsum depends on the gypsum stone. In the Semnan Sahar factories group, the purity of the gypsum stone is 94%, it has very good whiteness, and the final product, due to its fine mesh and very low impurities, works very well for whitewashing and tooling.
