Zincite (zincite), - oxide zinc, contains the admixture of zinc. Glance (glitter, glare) almost diamond; transparent. Colors: red, orange, brown-red. A line orange-yellow. Fracture, break padman. Fragile. Cleavage perfect absolute. Appears in skarn. Zincite is a red or yellow mineral consisting of zinc oxide in hexagonal crystalline form. It occurs in metamorphosed limestone. Formula: ZnO.
Crystals (hexagonal Crystal structure) are rare, usually there are grainy aggregates or dispersion, dissemination. Rare and practical value however much ore has, however it very valued collectors and sometimes exposed to cutting as jeweller stone. Places of display: Poland, USA, Tasmania, Spain. Standard - Zincite in an association with Franklinite (ZnFe2O4) from a deposit mines Franclin, state is New Jersey, USA.
The crystals of zincite are pyramidal; in nature they meet rarely. Usually mineral is presented as mass of the typical dark orange-red colouring. To his thicket everything is accompanied by Franklinite and Willemite.
Diagnostic indication.
Zincite easily recognized on the characteristic colouring. In addition, the important element of diagnostics is an association with Willemite, different a capacity for fluorescence.
Origin provenance genesis.
Zincite - typical mineral of contact origin, appearing as a result of physical and chemical reactions, caused introduction of magma in surrounding rocks.
Deposit minefield mine and use.
The most famous deposits of zincite are Franclin Fernas and Sterling-khill in the state New Jersey, where mineral is associated with white and red Calcite, green Willemite, grey tephroite and black Franklinite. Very beautiful standards, very valuable from the scientific point of view, are there found. Reported about a zincite from Poland, Spain and Australia. Once important zinc ore, Zincite after exhaustion of the American deposits mines grew into the real rareness for a collector.

DOPOG #4.1 
Flammable hard solid substance matters, self-reactive matters and solid desensitized explosives
Risk of fire. Flammable or combustible matters can catch a fire from sparks or flame. Can contain self-reactive matters, apt at exothermic decomposition in the case of heating, contact with other matters (such as: acids, connections of heavy metals or amines), to the friction or blow.
It can result in the selection of harmful or flammable gases or pair or spontaneous combustion. Capacities can burst at heating (dangerous, perilous - does not burn practically).
Risk of explosion of the desensitized explosives after the loss of desensitizer

DOPOG #4.3 
Matters substances, which select flammable gases at a contact with water
Risk of fire and explosion at a contact with water.
Gruz, which had scattered, it is necessary to cover and hold dry
Sine-blue rhombus, number of DOPOG, black or white flame
DOPOG #5.1 
Matters substances, which oxidize
Risk of stormy reaction, self-ignition or explosion at a contact with combustible or flammable matters
To shut out formation of mixture of load with flammable or combustible matters (for example by sawdusts)

DOPOG #6.1 
Toxic non biological matters substances (toxin)
Risk of poisoning at inhalation, contact with a derma or swallowing. Make a danger for a water environment or sewage system
To use a mask for emergency abandonment of transport vehicle
White rhombus, number of DOPOG, black skull and crossed cross-bones
DOPOG #8 
Corrosive (caustic, pungent, acrid) substances matters
Risk of burns as a result of eating away of derma. Can stormily react between itself (components), with water and other matters. Matter, that spilled / scattered, can select a corrosive pair.
Make a danger for a water environment or sewage system
