Quartz Stone Variety Identification

Quartz is a kind of mineral which is easy to become liquid when heated or pressed. Is also a very common rock mineral, in the three major types of rocks are there. Because it is the largest in the igneous rock, so usually the lack of a complete crystal face, mostly filled in the other first crystallization of rock-forming minerals in the middle. The composition of quartz is the simplest silica [ie, silica. Silicon: silicon old name] (sio2), glass luster, no cleavage surface, but with shell-like fracture. Microcrystalline quartz is called chalcedony, agate or jasper. Pure quartz is colorless, but because of the transition elements often contain impurities and show different colors. Quartz is very stable, not easy to weather or change for his kind of minerals. According to the degree of crystallization of SiO2 can be divided into crystalline crystalline single crystal quartz, polycrystalline quartzite jade.

feature

1, scraping does not spend

Quartz stone is the quartz content of up to 94%, quartz crystal is the natural hardness of diamond after the natural minerals, the surface hardness can be up to Mohs hardness of 7.5, much larger than the kitchen used in the blade and other tools, hurt.

2, do not pollute

Quartz stone is made in a vacuum under the conditions of the same, a dense non-porous composite material, the quartz surface of the kitchen, such as acid and alkali have excellent resistance to corrosion, the daily use of liquid substances will not penetrate its internal, long time The surface of the liquid only with water or clean and bright cleaning agent can be wiped with a rag, if necessary, the blade can be used to scrap the surface of the retentive.

3, with the old

Quartz stone glossy bright surface is after more than 30 complex polishing process, will not be blade shovel scratches, will not penetrate the liquid material, will not produce yellowing and discoloration and other issues, daily cleaning only rinse with water You can, easy. Even after a long period of use, the surface is also the same as the new table with the bright, no maintenance and maintenance.

4, can not burn

Natural quartz crystal is a typical refractory material, the melting point of up to 1300 degrees above, 94% made of natural quartz quartz flame completely flame retardant, will not be due to contact with high temperature and lead to burning, but also with artificial stone and other countertops can not match the high temperature characteristic.

5, non-toxic without radiation

Quartz stone surface smooth, smooth and no scratches retention, dense non-porous material structure makes the bacteria nowhere to hide, can be in direct contact with food, safe non-toxic.

High-quality quartz stone with a selection of natural quartz crystal minerals, the SiO2 content of more than 99.9% or more, and in the manufacturing process to purify, the raw materials do not contain any possible lead to radiation of heavy metal impurities, 94% of the quartz crystal and other Of the resin additive makes the quartz stone without the risk of radiation contamination.

Variety identification

Monocrystalline SiO2 gemstone transparent, crystal shape of the SiO2 single crystal (including double crystal), mineral name for the single crystal quartz, that is, the broad sense of crystal, narrow crystal refers to the colorless and transparent varieties.

(1) the basic properties of crystal Crystal is a triangular system, the common crystal shape for the column, the main simple form for the hexagonal column, rhombohedral, columnar crystals often developed stripes and polygonal erosion, crystal is a crystal positive light, With a unique bovine eye interference map, the refractive index of 1.544-1.553, birefringence 0.009, very stable, no cleavage, shell-like fracture, fracture can be with grease luster, Mohs hardness 7, density 2.65g / cm. Crystal is usually colorless and transparent, but with impurities can appear in a variety of colors, according to the color can be divided into amethyst crystal, citrine, smoke crystal and other varieties.

(2) crystal varieties and identification of crystal: colorless transparent pure silica crystal, which can contain a wide range of inclusions, common negative crystal, fluid inclusions, solid inclusions. Negative crystal is an important basis for determining natural crystal. Solid wrapped body wrapped in rutile, tourmaline, actinine was fine needle-like orientation arranged in the quartz crystal, like hair, used to call this crystal crystal, and some other solid inclusions in the crystal can be The formation of a beautiful picture, as people love the ornamental stone.
