1. Weight: The good quartz stone plate is pressed by the press, while the poor quartz stone is pressed by the heavy press for casting production. The plate density is higher, so the quartz stone of the same size will be heavier. The quartz stone content varies from 80% to 94%. The higher the quartz content, the better the quality of the quartz stone table.
2. Thickness: There are 12 cm and 1.5 cm quartz stone as the top of the cabinet. Because the hardness of quartz stone is higher than that of artificial stone, it is recommended to use 1.5 cm thick quartz stone.
3. The key and other hard objects scrape quartz stone. The main component is quartz sand, that is, silicon dihydrogen. In the big eyes, the hardness is basically second to diamond. If it is really good quartz stone, it will only have a line after scraping with the key, and it will be less obvious after scrubbing. The poor quartz stone table top contains calcium powder and other inferior materials will have traces and white powder after scraping with the key.
4. Soy sauce test: good quartz stone mesa soy sauce will not bleed after being poured on it for several days. Poor quality quartz stone table top oozes color in a day.
The above differences can only be used for reference, and many can only be distinguished from practical processing.
