Is Gypsum cancerous?
Gypsum can irritate mucus membranes and the respiratory system. Talc or talcum powder can irritate the respiratory system, damage the lungs, and can contribute to the development of cancer. Exposure to powdered mica can lead to fibrosis of the lungs and long-term respiratory difficulties.
Hereof, Can gypsum kill you?
Most of the harm from drywall compounds, especially fibreglass (which isn’t in all board types), is from inhaling the dust. Prolonged exposure can lead to serious lung disease and early death. Eating it, though your body isn’t gonna thank you for it, won’t kill you as far as I am aware.
What is another name for gypsum? Alabaster. Fine-grained, slightly colored. Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.

How is gypsum made?
Gypsum is made up of oxygen, sulfur, calcium and water. As evaporation occurs the sulfur is not protected by the water and oxygen contacts sulfur bonding with it to form a sulfate (SO4 2). The sulfate then bonds with calcium (Ca) and water (H2O) to create gypsum.
Why gypsum is added in cement?
Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement.
