Gypsum may contain trace amounts of free crys talline silica. Prolonged exposure to respirable free silica can aggravate other lung conditions and cause silicosis, a disabling and potentially fatal lung disease. Exposure to gypsum dust may cause irritation to the moist mucous membranes of the nose, throat, and upper respiratory system. It

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 2H 2 O. 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.A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including ...

The calcination of gypsum by continuously feeding fine gypsum spirally downwardly through a cylindrical zone into which heated air is injected almost tangentially forming a spiral air conveyor. The calcined gypsum collected at the bottom is of unusual uniformity and can be readily and controllably varied by controlled variations in the characteristics of the heated air conveyor.

It is a fine powder which is easy to measure out and use. Decent quality bag for a fertilizer also. I have used this succesfully to soak grains for oyster mushroom mycellium innoculation. It takes about 5 gallons of hot water to thoroughly dissolve 2/3 cups of the gypsum powder and some of the powder still falls out when it cools.

Such a W/HH ratio results in a humid HH powder, which is hard to hydrate. For many centuries gypsum pieces have been made using W/HH ratios close to 1.0, which produce low-viscosity water-plaster suspensions that help the conformation of gypsum. The density, mechanical strength and water resistance of those gypsum parts is low.
