The oldest traces of plaster renders are 9,000 years old, and were found in Anatolia and Syria. We also know that 5,000 years ago, the Egyptians burnt gypsum in openair fires, then crushed it into powder, and finally mixed this powder with water to make jointing material for the blocks of their monuments, such as the magnificent Cheops Pyramid for example.

the job site. Gypsum panels are very heavy, awkward loads posing the risk of severe back injury. Use proper lifting techniques. Conditions for safe storage, including any incompatibilities Store in a cool, dry, wellventilated place. Store away from incompatible materials. Protect product from physical damage.

The present invention is an apparatus and process for cooling and desteaming hot calcined stucco used in the production of gypsum boards or bagged plaster. The apparatus is a fluid bed stucco cooler and comprises a cooler housing having a plenum having a stucco inlet and stucco outlet. The stucco cooler includes a rotating disk in the plenum.

Heat absorbed from the process must be dissipated to allow reuse of the water. Cooling towers, spray ponds, and evaporative condensers are used for this purpose. Open recirculating cooling systems save a tremendous amount of fresh water compared to the alternative method, oncethrough cooling.

These gypsum deposits became sedimentary rock beds when they were cemented together. Dissolved particles and decayed matter carried by water were left between gypsum grains, making the natural cement that holds sediment together. Other sand and soil was deposited on top of the gypsum layer and pressed down on it creating the gypsum bed.

DESCRIPTION

Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.
