Two ways of distinguishing the quality of quartz stone

First， quartz stone is brittle and not bright and surface with very fine lines, with wood tapping surface pound, or Bang's voice quality is very good.

Second，Quartz stone bright and crisp, with wood beat easily broken, surface texture is very rough, or no lines, indicating that the quality is suspect, may be made of inferior materials, the quality is poor. In the face of quartz stone mixed market, in this to provide three simple methods, lend you a pair of eye, easy to identify true and false quartz stone.

Hardness is wear resistance identification, a simple method is to use steel row, with the key no differential effect.

To "Spring Lyric" as an example, the knife across, leave white print is false quartz stone, because plate hardness was inferior to that of steel, steel knife cut surface, exposing the inside white. And pure quartz stone is across the blade, leaving only a black mark is knife row real quartz stone, but left traces of steel caused by, one black and one white, true and false stand now.
And a move is from the acid and alkali resistant performance to identify, hydrochloric acid for industrial use on the surface of the plate, Mashi Eshi because anti acid and alkali, so drop acid up like water drops so not from a chemical reaction, and false quartz stone will bubbles, it is because false quartz stone is not anti acid and alkali, sulfuric acid with the produced chemical reaction.
The price of pure quartz stone is higher, and the price of fake quartz is low.
