two meters). These tremendous crystals shaped in a novel setting with regular large temperatures along with a saturated sulfate Remedy.
Cleavage: Gypsum reveals outstanding cleavage in a single direction, that means it quickly splits into slender, flat sheets or plates when subjected to mechanical gypsum tension. This residence causes it to be suited to generating gypsum board (drywall) and plaster solutions.
