Not in the mainstream quartzite, at least in Beijing. It is difficult to judge, but the quality of quartz stone has appraisal standards.

For example:

Hard enough: Harder than ordinary iron knives. If your kitchen knife rubs against the high-quality quartz stone table, you will be surprised to find that my knife has been wiped off, but the quartz stone is fine.

Fire resistance: Quartz stone should not be artificial stone such as acrylic. He can't light the flame retardant. Try it with your lighter. If so, congratulations. You don't need to buy this quartz stone.

Dense: High quality quartz stone has high density. If you drop a drop of water from your mineral water bottle, it won't penetrate into the countertop, but it will always be in the shape of a drop of water. However, if you take a sip of water, it will flow.

After-sales: If you don't even have an after-sales service, you know!
