Apatite

== Description ==
A naturally occurring mineral of calcium fluor-phosphate. Apatite is found throughout the world with numerous deposits in Europe (Germany, Spain) and North America (Ontario, Massachusetts, California, Mexico). It is colorless when pure, but impurities can give it a white, green (asparagus stone), blue (moroxite), yellow, or violet color. Bones, both human and animal, are composed of Hydroxyapatite, mixed with protein (ossein) and small amounts of other minerals, such as calcium carbonate. Apatite is commercially used as a fertilizer.
== Synonyms and Related Terms ==
asparagus stone (green); moroxite (blue); fluorapatite; phosphorite; Apatit (Deut.); apatite (Fr., Port.); apatito (Esp.); apatiet (Ned.); apatyt (Pol.)

Aquamarine

== Description ==
A transparent blue-green beryl gemstone. Aquamarines have been mined or gathered as gemstones since the late iron age (500-50 BCE). They are found in Brazil (Minas Gerais, Espirito Santo, Bahia), Siberia, the Urals, Madagascar, Sri Lanka, India, Myanmar, Nigeria (since 1983), Mozambique (since 1991), and the United States (Maine, New Hampshire, Connecticut, North Carolina, Colorado). Aquamarines are composed of a beryllium-aluminum silicate mineral with trace amounts of iron providing the blue-green color. They are sometimes heat-treated to remove greenish tones. Aquamarines were popular for jewelry in the 19th century. The largest recorded aquamarine was discovered in 1910 and weighed 110 kg (242 pounds). A dark blue beryl, called Maxixe beryl, occurs very rarely naturally and fades in light or heat. The dark blue color is also produced artificially through lengthy irradiation of pink beryl.

Aquatint

== Description ==
An intaglio etching technique invented in the 1760s by J.B. LePrince. Aquatints were popular until the late 1830s. To produce an aquatint the metal plate is sprinkled with a finely-powdered resin (asphaltum, rosin, etc.). The plate is heated to melt the resin, then cooled and placed in an acid bath. The acid lightly etches areas not covered with the resin. The results in a plate with fine pockmarks. The abscence of ink due to the random holes produces a variation in tone that resembles a watercolor washes.
