Serpentine: Background and Summary
Serpentine is a group of minerals that are commonly found in metamorphic rocks. It is typically green in color and has a waxy or oily texture. Serpentine can be identified by its unique color and texture, as well as its tendency to break into small, fibrous pieces. It is also often associated with other minerals, such as olivine and pyroxene.Serpentine has a wide range of uses, both industrial and decorative. It is commonly used as a building material, particularly in the form of decorative tiles and countertops. Serpentine is also used in the production of asbestos-free brake pads and other friction materials. In addition, it is used as a source of magnesium and is often added to fertilizers to improve soil quality.
Despite its many uses, serpentine is also associated with health risks. Because it often contains asbestos, prolonged exposure to serpentine dust can lead to respiratory problems and even cancer. As a result, it is important to handle serpentine with care and to take appropriate precautions when working with it.
