Zanzibar copal

== Description ==
A hard variety of copal resin found as semi-fossilized specimens on the ground or as exudations on living trees (species Trachylobium such as T. verruscosum and T. mossambinecense), found on the island of Zanzibar and areas of nearby African mainland. The most valued pieces are fossilized specimens from trees that are no longer living. Zanzibar copal is a very hard, smooth and shiny resin that is used to make a dark oil varnish. Some specimens of Zanzibar copal are misrepresented as amber.
== Synonyms and Related Terms ==

Zapon dyes

== Description ==
[BASF] A registed trademark until 2010 for a series of synthetic dyes. Zapon dyes are initially soluble in water and most organic solvents. However, they hydrolyze in water or air to form a stable, insoluble product. They belong to the group of organic metal complex dyes , mostly with chromium or copper or cobalt as the central atom.
Zapon dyes are used as a component of transparent lacquers (such as Zapon lacquer) for metals and for wood stains. Some examples are:

Zapon lacquer

== Description ==
[Celluloid Zapon Co, Springfield NJ] Originally a name for a cellulose nitrate varnish (patented 1887) in a solvent mixture containing amyl acetate, butyl acetate and propyl acetate. Zapon lacquer dried to a very thin transparent film that was originally sold as a varnish for polished metals parts. Rathgen (1905) listed procedures for Zapon's use on artwork as a metal coating and stone consolidant, By 1907, an artist newsletter recommended it as a fixative for watercolors (Ellis 1996). Zapon-Lack was also used for a short time from in the early 20th century as an isolating varnish for paintings, however it was found to turn yellow with age (Doerner 1934). Another unsuccessful use of Zapon, was as a consolidant for manuscripts degraded by iron gall inks (Reissland 2000). The name, Zapon-Lack, is currently a German tradename for a mixture of cellulose nitrate in amyl acetate, ethanol, and ethylacetate.

Zein fiber

== Description ==
Regenerated protein fibers made from corn and maize. Zein fibers were commercially sold as Vicara from 1948 to 1957. They were made with the crushed meal of corn and maize after the oil was extracted. The meal is dissolved in an alkali bath then forced through spinnerets to form fine fibrils that were hardened with formaldehyde. Fabric made from zein fiber is soft, tough and strong and has the warmth of wool. It is resistant to mildew, insects, sunlight, and temperatures to 140 C. Vicara was usually blended with cotton, wool, or rayon. It was used in suits, sweaters, blankets and pile fabrics.

Zeolite

== Description ==
A group of naturally occurring minerals composed of alkali-hydrated aluminum silicates. Examples are analcite, chabazite, heulandite, natrolite, phillipsite, scolecite, stilbite, and thomosonite. Zeolites are soft, fibril minerals with numerous interconnecting voids that can absorb water as well as other liquids and gases. Additionally, zeolites have an ion-exchange capability since its alkaline cations, such as calcium, are mobile and capable of switching with other cations that pass through the cavities. By varying pressure and heat, synthetic zeolite matrices can be prepared from silicon dioxide and aluminum oxide with selected pore sizes and textures ranging from gelatinous to sand-like. Zeolites are used as absorbents, catalysts, desiccants, filters, ion exchange resins, and molecular sieves.

Zinc

== Description ==
A bluish-white, lustrous metallic element. Zinc occurs with an abundance of 0.02% in the earth's crust in the minerals smithsonite (ZnCO3), sphalerite (ZnS), zincite, willemite, and gahnite. Zinc was discovered in prehistoric times and it was first isolated from the ores in India in the 13th century by the reduction of calamine. China was mass producing zinc by the 16th century. In Europe, commercial production began after techniques for its isolation were discovered by Andreas Sigismund Marggraf in Germany in 1746. The present major mining producers are : China, Peru, Australia, United sates, Canada, India, Kazakhstan, Bolivia, Mexico, Ireland. The malleable metal is ductile at 150 C, but becomes so brittle at 180 C that it can be powdered. It is most commonly used as an anti-corrosive galvanized coating for other metals. Metallic zinc is also used in alloys, such as brass, to increase workability. Zinc oxides are used in artists pigments, photocopiers, sunscreens, and antiseptic ointments. Zinc sulfides are used as phosphors in cathode ray tubes. Zinc containing pigments include zinc white, zinc yellow, and lithopone.
