Zinc chloride

== Description ==
White deliquescent granules or fused pieces. Zinc chloride acts an astringent and antiseptic and has been used to deodorize, disinfect, and embalm specimens. It is used on wood for preservation and fireproofing. With metals, zinc chloride can act as a flux, etchant, cement, and colorant. For textiles, it has been used to mercerize cotton, weight fabrics, mordant dyes, and vulcanize rubber. It is also used in the manufacture of artificial silk, dyes, cold-water glue, and magnesia cements. As a microscopy reagent, zinc chloride is used to separate silk, wool, and plant fibers.

Zinc green

== Description ==
Name used for three different paint pigments. 
1) Most commonly, zinc green refers to a mixture of zinc yellow and Prussian blue. This composite pigment is permanent to light but not to alkali or water. 
2) Zinc green is also incorrectly used for cobalt (Rinman's) green. Cobalt green is a solid solution of zinc oxide and cobalt oxide, CoO.ZnO. It is a fast drying, permanent pigment that has been available since the mid-1800s. Cobalt green was developed by a Swedish chemist named Sven Rinman in 1780. 
3) The common name for zinc chrome green.

Zirconium

== Description ==
A soft white metallic element. Zirconium occurs naturally in the minerals zircon, malacon, baddeleyite, zirkelite, eudialyte, and some rare earth minerals. Its abundance in the earth's crust in 0.023%. Zirconium was discovered by Martin Klaproth in 1789 and first isolated as a metal by Jöns Jacob Berzelius in 1824. Because zirconium has good strength and is resistant to heat, corrosion, and nuclear radiation damage, it is widely used in nuclear reactors. It is also used in lamp filaments and flash bulbs. In the ceramic industry, zirconium silicate and zirconium oxide are used as opacifiers and glaze frits.
