Anglesite

== Description ==
A naturally occurring mineral composed of lead sulfate. Anglesite occurs naturally as an oxidation product of galena (lead sulfide). First recognized as a mineral in 1783 by Dr. Withering in the Anglesey copper mine, anglesite is now mined in England, Wales (Anglesey), Scotland (Leadhills), Italy (Sardinia), Australia, Mexico (Chihuahua), and the United States (Pennsylvania, Idaho, Nevada). Anglesite is a lustrous white to colorless stone that can be transparent or opaque. It is primarily used as an ore source for lead. White crystals of anglesite also occur as a lead corrosion product (Selwyn 1996).

Angora

== Description ==
The long, fine hair from an Angora rabbit. The silky hair from an Angora goat is sometimes called angora but more often called mohair. The Angora rabbit is native to Asia Minor, domesticated by the Trelicians since the 6th century, and only bred in Europe since the early 19th century. The white French rabbit produces high-quality, soft hair. The fur is trimmed every three months to produce clippings that are 3 inches long. Angora dyes readily, but is difficult to spin because of its fine texture. It is usually mixed with wool or other fibers for weaving cardigans and gloves. Angora easily felts and sometimes felts on the rabbit itself if not regularly groomed. 
== Synonyms and Related Terms ==
angorakanin (Sven.); angora (Esp. Fr., Ned.)
== Risks ==
Deteriorated by alkalis 
Susceptible to mold, mildew and static electricity
== Physical and Chemical Properties ==
Guard hairs are a dumbbell shape; diagonal scales with serrated edges 
Fine hairs are oval; flattened scales with wavy edges
Angora rabbits are domesticated and therefore do not fall under IUCN RED List considerations. For the same reasons (of domestication), their wool and woolen products are not regulated under CITES. National trade regulations may still be in effect.

Anhydrite

== Description ==
A naturally occurring mineral of anhydrous calcium sulfate that is often found in gypsum deposits. Anhydrite was first identified as a mineral in deposits at Innsbruck, Austria in 1794. Other major deposits occur in Canada (Ontario), and the U.S. (Arizona, New Mexico). Anhydrite can be transparent or translucent and has a lustrous sheen. It occurs in several colors such as white, gray, blue, pink, red, and lavender. Anhydrite was used in ancient Egypt for carved objects and vessels, many of which are in the shape of animals (Fay, 1998). Powdered anhydrite has also been found as a filler in the gesso grosso ground layers of Italian paintings and polychromed sculpture. Currently, the colorless, inert pigment is often used as a filler in paper, paints, and plastics.
