Presentation transcript:

Gypsum is a mineral commonly found in sedimentary deposits. It is a lot like Halite, Sulfur, Anhydrite, Calcite, and Dolomite.

Gypsum can be many different colors such as green, yellow, orange, clear, white, gray, red, and brown.

Gypsum has a white streak (That is the color that comes off the mineral when it is scraped on a surface.)

Gypsum can have a silky, sugary or glassy luster (That is how the mineral looks when it reflects light.)

Gypsum is a 2 on the Moh’s scale of hardness (That is a scale that measures how much the mineral can resist scratching.) Two softer minerals are Graphite and Talc. Two harder minerals are Calcite and Diamond.

Gypsum has a Monoclinic crystal shape.

Gypsum has perfect cleavage (That is how straight the line will be when it is cut.)

Gypsum is found almost all over the world in layered sedimentary deposits.

 Gypsum is used in Wallboard, Cement and plaster of Paris  Its chemical composition is CaSO 4 2H 2 O.(Hydrous Calcium Sulfate.)  Gypsum can be made into beautiful Jars.
