{Butter of zinc} (Old Chem.), zinc chloride, {ZnCl2}, a
deliquescent white waxy or oily substance.
{Oxide of zinc}. (Chem.) See {Zinc oxide}, below.
{Zinc amine} (Chem.), a white amorphous substance,
{Zn(NH2)2}, obtained by the action of ammonia on zinc
ethyl; -- called also {zinc amide}.
{Zinc amyle} (Chem.), a colorless, transparent liquid,
composed of zinc and amyle, which, when exposed to the
atmosphere, emits fumes, and absorbs oxygen with rapidity.
{Zinc blende} [cf. G. zinkblende] (Min.), a native zinc
sulphide. See {Blende}, n.
(a) .
{Zinc bloom} [cf. G. zinkblumen flowers of zinc, oxide of
zinc] (Min.), hydrous carbonate of zinc, usually occurring
in white earthy incrustations; -- called also
{hydrozincite}.
{Zinc ethyl} (Chem.), a colorless, transparent, poisonous
liquid, composed of zinc and ethyl, which takes fire
spontaneously on exposure to the atmosphere.
{Zinc green}, a green pigment consisting of zinc and cobalt
oxides; -- called also {Rinmann's green}.
{Zinc methyl} (Chem.), a colorless mobile liquid {Zn(CH3)2},
produced by the action of methyl iodide on a zinc sodium
alloy. It has a disagreeable odor, and is spontaneously
inflammable in the air. It has been of great importance in
the synthesis of organic compounds, and is the type of a
large series of similar compounds, as zinc ethyl, zinc
amyle, etc.
{Zinc oxide} (Chem.), the oxide of zinc, {ZnO}, forming a
light fluffy sublimate when zinc is burned; -- called also
{flowers of zinc}, {philosopher's wool}, {nihil album},
etc. The impure oxide produced by burning the metal,
roasting its ores, or in melting brass, is called also
{pompholyx}, and {tutty}.
{Zinc spinel} (Min.), a mineral, related to spinel,
consisting essentially of the oxides of zinc and
aluminium; gahnite.
{Zinc vitriol} (Chem.), zinc sulphate. See {White vitriol},
under {Vitriol}.
{Zinc white}, a white powder consisting of zinc oxide, used
as a pigment.
