Gypsum has been used since ancient times to build monuments that have lasted for centuries. The oldest traces of plaster (gypsum) renders are 9,000 years old, and were found in Anatolia and Syria. The pyramids of Giza in Egypt, for example, is the only surviving wonder of the ancient world. This noble material has been a constant presence in construction and renovation through the ages. The ancient Greeks also used a transparent quality of gypsum "selenite" to construct statues and windows for their temples.
Today gypsum is used widely in a lot of applications of our daily life and in different sectors, such as the construction industry, health, agriculture, decoration, paintings and more. In general, gypsum is suitable for all interior plastering except areas directly exposed to free water or severe moisture and therefore is not recommended for exterior applications. Gypsum is also non-combustible and resist to fire for extended periods of time.
What is gypsum actually?
Gypsum, a sedimentary rock scientifically named "Calcium Sulfate", was created from the evaporation of sea water that was trapped in lagoons of subsoil and is usually found in mountains. The impure gypsum (that it is found in the subsoil) can have different color variations, such as grey, brown or red. Please go to Wiki here for further reading.
