fused quartz

La description

Fused silica(quartz) is manufactured from deliberated silica sand, through high temperature fusion, cooling, smash and selecting. The appearance is colorless and transplanted, a bit of them will transplanted frog shape. And it can be processed to all kinds at the request of customers.
