The properties of gypsym before and after setting affects the outcome of the process gypsum is used for For example, the finess of the gypsum affects the ability of the gypsum to adapt to fine details of the impression material
These properties and behavior determine the specific use of the gypsum product Properties of strength, abrasion resistance, and solubility and behaviors of setting time and expansion have varying importance, depending on the application
Gypsum is a natural insulator, feeling warm to the touch when compared to a more ordinary rock or quartz crystal Sheets of clear crystals can be easily peeled from a a larger specimen Gypsum crystals can be extremely large - ,
Although it does not have the specially enhanced fire-resistive properties of type ‘X’, regular core gypsum board affords a degree of natural fire resistance For information about the use of gypsum board in fire-resistant construction systems consult GA-600, Fire Resistance Design Manual

Plaster of Paris was first named for a gypsum deposit that was located in Paris, France While gypsum is a hydrated salt, the plaster is the result of reformed gypsum It was eventually discovered that when mixed with water, the plaster become hard, durable and resistant to temperature and water .
It is more expensive than natural gypsum products but when product is properly made it’s properties are equal or exceed to natural gypsum products 14 SETTING REACTION When plaster is mixed with water it takes up 15 molecules of water ie , it regains the water of crystallization and becomes Calcium Sulphate dihydrate
Gypsum plaster: Gypsum plaster,, white cementing material made by partial or complete dehydration of the mineral gypsum, commonly with special retarders or hardeners added Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water For especially hard finish
A Plasterboard Plasterboard is used for partitions and the lining of walls, ceilings, roofs and floors The properties of plasterboard can be modified to meet specific requirements, such as fire resistance, humidity resistance, shock resistance, etc
