zincite

There are also two minerals, zincite and hemimorphite, which have been historically called calamine.

It occurs naturally as the mineral zincite but most zinc oxide is produced synthetically.

The mineral zincite usually contains manganese and other impurities that confer a yellow to red color.

The mineral association (assemblage) from Franklin includes willemite, zincite and franklinite.

The result was astonishing: with a zincite (zinc oxide) crystal he gained amplification.

In 1923 he found that biased zincite (zinc oxide) crystals could amplify a signal.

The Soviet authorities did not support him, and zincite crystals were hard to come by because they had to be imported from the United States.

Franklinite and zincite are not fluorescent.

Jerrygibbsite has been found to occur in contact with willemite, zincite, and sonolite in an uncommon assemblage.

Unlike the other silver halides, iodargyrite (AgI) contains a hexagonal zincite lattice structure.

One variation consisted of a pair of different crystals with their faces touching, such as zincite touching bornite or chalcopyrite.

Sonolite has been found in association with calcite, chlorite, franklinite, galaxite, manganosite, pyrochroite, rhodochrosite, tephroite, willemite, and zincite.

It occurs with mooreite, willemite, fluorite, hydrozincite, pyrochroite, zincite and rhodochrosite at Sterling Hill, New Jersey.

It is a rare secondary mineral formed by weathering of zinc-bearing slag, and is associated with native zinc, hydrocerussite, diaboleite, zincite and hydrozincite.

It occurs in association with: zincite, willemite, franklinite, rhodonite, jacobsite, diopside, gageite, bustamite, manganocalcite, glaucochroite, calcite, banalsite and alleghanyite.

One decade later, a study of kohl manufactured in Egypt and India found that a third of the samples studied contained lead, while the remaining two thirds contained amorphous carbon, zincite, cuprite, goethite, elemental silicon or talc, hematite, minium, and organic compounds.
