What are the chemicals in glass?
Common raw materials are quartz sand, feldspar, calcite, calcium carbonate, three, two aluminum oxide, sodium carbonate, borax and so on.
(some of these ingredients are repeated, and the content of the active ingredients should be carefully calculated when firing the glass) In addition, there are some trace elements, such as metal oxides, used for colored glass, shielding electromagnetic, optical glass and so on. Some other types of special glass materials account for a large proportion of raw materials, and may even contain quartz sand.
