2) delimit: with the use of a sharp tool on the surface of quartz stone, if it is easy to be drawn out of the traces that can not be swab out, it shows that its hardness is not enough.
3) bubble: quartz stone is placed in easily dyed articles (such as soy sauce, coffee, nicotine), and after a period of time, if quartz stone is dyed, its permeability is poor.
4) smash: if a certain weight object is hit on the surface of quartz stone, it can be seen the degree of fragmentation. If fragmentation is too much, it means that its compactness and hardness are not enough.
