Minerals are natural elements or compounds formed through geological processes in the earth’s crust. Minerals range from pure elements to simple salts or complex silicates. Minerals are basically inorganic, homogeneous solids with a crystal structure and a definite chemical composition. The chemical makeup is different for each mineral. Chemical tests and x-rays are needed to identify a mineral. Currently just over four thousand minerals are known to mankind. Minerals are being used in various walks of life – at work, in schools and homes. One such area is the cosmetic industry.

Elements and compounds are the building blocks of minerals. Minerals made up of only one element are called native minerals like silver, gold, mercury and copper. Minerals composed of compounds are simply referred to as minerals.

Mineralogy is the study of minerals. Bare minerals that are used to make cosmetics consist of cosmetic grade minerals and mineral pigments. Bare minerals are obtained from various sources like plants, plant sources and the earths crust. Bare minerals may include pure elements, simple salts or complex silicates. Minerals are made of elements like oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Minerals are identified by their color, luster, transparency, hardness and florescence. They are also identified by their magnetism, odor, solubility and radioactivity. Minerals are classified as silicates, carbonates, sulphates, halides and oxides. They are also classified as sulphides, phosphates, organic and mineraloids, on the basis of their chemical composition.

The human body requires certain bare minerals like, potassium and magnesium, to function properly. They are needed for body functions like building strong bones, transmitting nerve signals and maintaining a normal heartbeat. They are also used to air hormone production in the body. One such area is the cosmetic industry. Bare minerals are used to make cosmetic products called mineral makeup. Cosmetics made out of bare minerals are called mineral makeup. These cosmetics contain no chemicals and are a popular natural option to traditional makeup.
