This unique rock is mined (or quarried) and crushed, following which it is then ground into a fine powder and heated to about 350 degrees Fahrenheit, driving off three fourth of the chemically combined water in a process called calcination.
The calcinated gypsum (hemihydrates) gradually forms into what is known as Gypsum Plaster. It is then processed in an impact mill to transform into Gypsum Powder – popularly called “Plaster de Paris”. The same powder is used as a base for Gypsum Boards and other Gypsum products.
The powder manufactured by Etehad Watani Gypsum Company is pure white in color and processed according to international standards. It boasts the highest quality grade in the construction arena, making it extremely popular among customers.
