Raw materials of glass marble ball can only be glass, which is industrialized production. The main raw material are quartz sand, feldspar, calcite, glauber's salt and ore. They are heated to thousands of degrees above to reaction liquid glass. Usually children paly glass marble ball in 16mm,25mm,35mm,42mm diameter. And its production method can be described:
Making glass marble ball, first of all, all kinds of ore need to be crushed. Some powder is added into it. After composition, all things turn into glass liquid.
