MINERALS BENTONITE is an absorbent aluminium phyllosilicate, essentially impure clay consisting mostly of montmorillonite. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite.
MINERALS NATURAL STEATITE, TALC Talc is known for being the softest mineral on earth. It is number 1 on the Mohs hardness scale, and can be easily scratched by a fingernail. Talc is not commonly seen in collections, as it is usually uninteresting and fairly common, although a few deeply colored and crystallized examples are known and well sought after. Also very popular are the Talc pseudomorphs. Talc forms some very interesting pseudomorphs after many different minerals, and certain localities are known for the specific minerals replaced by Talc. Talc is a very important industrial mineral. Talc is crushed into powder to form talcum powder, which is the main ingredient in many cosmetics as well as some baby powders. Talcum powder was also used as a filler to prevent slipping in latex gloves, although its use is being replaced with corn starch which is safer for inhalation. Talc is highly resistance to heat and electricity, and is therefore used in electronics and as an insulator. It is also a filler material for paints, rubber and insecticides.
MINERALS MICA 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. In the paint industry, ground mica is used as a pigment extender that also facilitates suspension due to its light weight and platy morphology. The ground mica also reduces checking and chalking, prevents shrinkage and shearing of the paint film, provides increased resistance to water penetration and weathering, and brightens the tone of colored pigments. Ground mica also is used in the well-drilling industry as an additive to drilling “muds.”
