[0002] Quartz is one of the most widely distributed minerals on the earth's surface. There are many types of quartz. The raw materials used for daily ceramics include vein quartz, quartz sand, quartzite, sandstone, silica, opal, diatomaceous earth, etc. When silicon dioxide crystallizes perfectly, it is crystal. After silica gelation and dehydration, it becomes agate. After the hydrous colloid of silicon dioxide solidifies, it becomes opal.
