  • Blue Anhydrite Meanings

    Anhydrite is Gypsum that does not contain water. There exists the "natural type" and the "dehydrated type". When plaster is heated and dehydrated, it turns into a white powder. This white powder hardens with water. It is used for "statues", "casts", "blackboard chalk" and so on. Natural Anhydrite does not harden when it is powdered and water is added. The natural type has a .

    The intrinsic dissolution activity of the basal (010) and edge (001) surfaces of gypsum and polycrystalline calcium sulfate anhydrite crystals has been investigated, under far from equilibrium conditions, via the channel flow cell (CFC) method with off-line inductively coupled plasma-mass spectrometry (ICP-MS) for the measurement of dissolved Ca2+ from the crystal surface. This approach allows ...
