Even some bad businesses have used calcium powder instead of quartz sand to improve their interests. Now some people should ask about the difference between the calcium powder and the non calcium powder in the plate.
Everyone is in contact with what is known, quartz stone to wear, scratch, high temperature resistance, anti permeability and so on many advantages to quickly occupy the decorative stone market.

The first is the effect of plate hardness, quartz stone plate hardness Mohs hardness of 6 or more, for the six grade sheet can easily be scratched; and corrosion resistance is reduced; there is high temperature resistant performance, if the plate is easy to make contact with the object of high temperature cracking of plate.
How to identify the calcium powder in the quartz plate? In fact, the identification method is very simple, everyone knows that calcium and acid contact with the chemical reaction. But the use of oxalic acid or home clean toilet spirit, vinegar can be used, drop on the surface of the plate if bubbles show that the plate contains calcium powder.
