The main mineral found in Plaster of Paris (POP) is gypsum. Chemically, gypsum is known as calcium sulfate dihydrate (CaSO₄•2H₂O). When you heat gypsum, it loses water and becomes calcium sulfate hemihydrate—which is what we call POP. Once you mix it with water again, it hardens quickly and is used for ceilings, walls, and decorative work.
If you're working on interiors, you might also look into gypsum plaster, which is similar to POP but offers better strength and finish. Brands like Buildwell provide high-quality gypsum plaster products in India, and they’re widely used in modern construction.
