What is the raw material for making glass?
The 60% component of the crystal is "two oxide" (SiO2). The color of the crystal is due to the addition of two silicon oxide, which also contains a variety of trace metals. In the natural environment, and most of crystal mineral calcite, pyrite, iron ore, Hui various colors of mica, Biqian, granite, Jin Hongshi and other "symbiosis", and formed some suspected imaginary scene, the so-called "different" like crystal, crystal increased collection of fun and value.
The raw material of glass is crystal sand, and the chemical component is silica
The main raw material is quartz sand. Because of the high melting point of quartz sand, it is necessary to add a flux of sodium carbonate (that is, our usual surface base) to molten glass when melting,
