Be Careful Of The Fake And Inferior Quartz Stone Slabs On The Market

Many friends have reported that there are many fake quartz stones and inferior quartz stones on the market but don't know how to distinguish them. Today I will teach you a quick and effective detection method.

We can use oxalic acid to test, drop oxalic acid on the pure quartz stone, there is no reaction. However, after the low-quality quartz stone is dripped with oxalic acid, many tiny air bubbles are generated. Why? This is because some small factories add calcium powder to the raw materials for filling in order to improve their profits. The calcium carbonate in the inferior quartz stone reacts with oxalic acid and produces bubbles.

It should be known that once calcium powder is added to the quartz stone slabs, the hardness, acid and alkali resistance and high temperature resistance of the quartz slabs will be greatly reduced.

Therefore, people who are decorating must keep their eyes open when buying quartz stone,make sure to choose pure quartz stone.
