There are two simple methods can be used to distinguish real quartz and faked one. ·First, scratching quartz with a steel knife instead of a key which is inoperative in doing this. Take [white crystal" for example, when the steel knife scratches it, if a white trace lefts, indicates that the white crystal is faked, because the faked white crystal is not as tough as the steel, so when the surface is cut off by the steel knife, it shows the inside. While pure quartz, if is scratched by the steel knife, will show a black trace of the steel, because it is tougher than the steel knife. So, real or faked quartz can be distinguished by the black or white trace. ·Second, use quartz`s acid and alkali resistance. Exactly, it is to drip industrial hydrochloric acid on the surface of the slab.The real quartz, which is resistant to acid and alkali, have no chemical reactions as if the industrial hydrochloric acid is water, but the fake quartz will give off bubbles because it is unable to resistant acid and alkali and has chemical reactions.
