The most common sulphate mineral. Found as both massive material, including the alabaster variety; and clear crystals, the selenite variety; and, parallel fibrous, the satin spar variety. Typically colourless to white, transparent crystals, thick tabular to lenticular, sometimes prismatic.
Gypsum is a very soft mineral that is easily identified by its hardness, cleavage, and solubility in water. Typically clear to white, gypsum may be colored reddish to brown or yellow if impurities are present.
Gypsum plaster is a 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.

Gypsum is a mineral with bendable crystals. It is often mined in the US, Mexico, Nova Scotia, and Australia. It is usually colorless, white, or gray in color. Although gypsum is a mineral, it can exist as a sedimentary rock. It is a sulfate containing oxygen and sulfur.
Gypsum, one of the most widely used minerals in the world, literally surrounds us every day. Most gypsum in the United States is used to make wallboard for homes, offices, and commercial buildings; a typical new American home contains more than 7 metric tons of gypsum alone.
Gypsum is the common name for the mineral calcium sulfate, which has a chemical formula CaSO 4. Gypsum bonds easily with water and is usually found in its natural state as hydrated calcium sulfate, with a chemical formula of CaSO 4 .2H 2 0.

Gypsum is a sedimentary rock and a crystalline mineral. "Gypsum is a soft, white to gray, "chalky" mineral composed of calcium sulfate and water," says Raymond Anderson of Iowa's Department of Natural Resources.
Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4 . 2H 2 O) is very similar to Anhydrite (CaSO 4 ).
Alabaster (gypsum), also a sedimentary rock, is a chemical deposit. Many varieties of sandstone and limestone, which vary greatly in quality and suitability for carving, are used for sculpture. Many varieties of sandstone and limestone, which vary greatly in quality and suitability for carving, are used for sculpture.
square meters (6,144 square feet) of gypsum wallboard (Mineral Information Institute, 2001). Worldwide, gypsum is added to portland cement, which is used in concrete for highways, bridges, buildings, and many other structures that are part of our everyday life. Gypsum is also extensively used as a soil conditioner on
★ Gypsum is a soft mineral, that is moderately soluble in water. The water solubility of this mineral is affected by temperature. Unlike other salts, gypsum becomes less soluble in water as the temperature increases. This is known as retrograde solubility, which is a distinguishing characteristic of gypsum. ...
Gypsum is an abundant mineral and takes forms including alabaster—a material used in decoration and construction as far back as ancient Egypt. The White Sands National Monument in New Mexico is the world's largest gypsum dunefield. This non-toxic mineral can be helpful to humans, animals, plant life, and the environment.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard.
Calcium Sulfate Minerals. Gypsum is the more common, hydrated form of calcium sulfate. In fact, it is the most common of all sulfate minerals. Gypsum's chemical formula is CaSO 4. 2H 2 O. The anhydrous (without water) mineral is called Anhydrite (CaSO 4).
A non-toxic mineral, gypsum can be helpful to humans, animals, plant life, and the environment. While the majority of gypsum produced in North America is used to manufacture gypsum panels or building plasters, gypsum can also be used:
A gypsum rosette is not a rose at all, it is a mineral which crystalizes in a unique rosette growth pattern. Their are many varieties, some look remarkably like a rose flower with its pedals open, while others from into beautiful bladed spheres.

Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers.
Selenite, also known as satin spar, desert rose, or gypsum flower are four crystal structure varieties of the mineral gypsum. These four varieties of gypsum may be grouped together and called selenite.
Jan 14, 2019· Gypsum, also known as calcium sulfate hydrate, is a naturally occurring mineral found in layers of sedimentary rock all over the world. It is formed by the evaporation and replenishment of waters containing calcium and sulfates.

Composition, Structure and Associated Minerals: Gypsum is a common mineral which is widely distributed in sedimentary rocks, often as thick beds. It frequently occurs interstratified with limestones and shales.
Gypsum Rock : Gypsum is an inert, safe mineral that has been used in a variety of applications for centuries. It was used as plaster in the Egyptian pyramids, and today it is most commonly used in homes and commercial buildings, as gypsum wallboard.
Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates. ... The principal use of ground mica is in gypsum wallboard joint compound, where it acts as a filler and extender, provides a smoother consistency, improves workability, and prevents cracking
Properties of Gypsum. Gypsum is a soft mineral composed of the elements calcium and sulfur, with the chemical formula CaSO4. Gypsum deposits come from the evaporation of lake and sea water, as well as in hot springs, and even volcanic vapors.
Manufacturers use gypsum in producing wallboard for home construction. The material is also used in cement and conditioning soil. Satin spar and alabaster gypsum are used for ornamental purposes, according to Geology.com. There are gypsum deposits in 85 countries and in 17 states of the United ...
