Introduction To Quartz
Quartz is one of the most widely distributed minerals on the surface of the earth. There are many types of quartz,quartz veins, quartz sand, quartzite, sandstone, silica, opal and diatomaceous earth. With ordinary sand, crystal is "with the mother of a" kind of material. When the crystal is perfect crystal crystal, silica gel is dehydrated after agate, silica water colloid solidification after becoming opal. When the silica grains are less than a few microns, they form chalcedony, flint, secondary quartzite.
Its use is quite extensive. Far in the Stone Age, people use it to produce stone axes, stone arrows and other simple production tools to hunt food and fight the enemy. Quartz clock, electronic equipment in the use of piezoelectric quartz film as the standard frequency. The glass made after melting can be used to make optical instruments, glasses, glass tubes and other products. Can also do precision instruments of bearings, grinding materials, glass ceramics and other industrial raw materials.
Quartz is a non-plastic material, and its clay in the high temperature generated mullite crystal to give porcelain higher mechanical strength and chemical stability, and can increase the translucent body, is the preparation of white glaze good raw materials.
During the period of the Republic of China, Jingdezhen was made by Quanshe Town. After the founding of new China, most of the stars, Duchang, Xiushui and other places of quartz, especially after 2000, the amount of quartz surge. Glaze in the amount of 10% to 30%, should be washed before use, to remove dirt impurities, placed in the kiln high temperature calcination, easy to crush.
