aorte Crystal identification

Consumers said that the understanding of the crystal to identify knowledge can buy money "at ease" how to identify genuine crystal ornaments

In recent years, a surge of "Crystal fever" make an exquisite crystal ornaments with its unique charm and went to unusual people, to people's lives brought great joy. How to identify genuine crystal ornaments? Mainly from the color, shape, crystal plane, gloss, hardness, cleavage fracture and the weight of inclusions, cracks characteristics, feel so identified.

Identification of items :

The natural crystal, artificial crystal, glass

Crystal : The six-party column, the Tripartite bipyramid, condenser, a cylindrical stripes and a double-crystal to crystal droplets convey to maintain their bead-like. Corynebacterium, crystal face a special plaque growth patterns or distorted peerless crystal, crystal with a parallel center Zhi cylindrical crystal bud.Without rules shape, surface water droplet spread immediately.

Sheen : Ming and Qing dynasties such as water, fat-light; Sheen blanch; Breathing Color color who redness.

Hardness : Mount's seven; 6.8-7; 5.5-6

Cleavage fracture : no cleavage, melt fracture, fracture parallel, chiropractors face obvious; Melt Fracture incomplete; Fracture parallel, chiropractors face significant

Inclusions characteristics : quality times are irregular inclusions, showing HAZE cotton bubble, irregular. Rules of the crumbs from inclusions, Bubble rules were round, oval-shaped or longer. Common rules of bubble wrap

Share :2.56 - 2.66; About 2.6; 2-2.20, but heavy lead glass.

Over touch : clear sense of cool; A cool flu; Wen flu

Optical properties : a crystal axis Zhengguang, 1.544-1.533 refractive index, optical nature and natural crystalline similar, Extinction faster than natural crystal slow, refractive index 1.40 about Quanxiaoguang, optical transmittance under polarizing glass, without the extinction phenomenon.
