Most glass is a mixture of silica obtained from beds of fine sand or from pulverized sandstone; an alkali to lower the melting point, usually a form of soda or, for finer glass, potash; lime as a stabilizer; and cullet (waste glass) to assist in melting the mixture.
The main constituents of an ordinary glass are, 1-soda Na2CO3 2-Lime, lime stone CaCO3 and 3- Sand SiO2.
sodium sulphate
fibre glass.
Borax
Chromium is useful in glass-making because it is one of the most powerful of all coloring agents used in the glassmaking industry and is used in the production of dark green glass.
Silicon ... or more correctly silicon oxide.
Borosillicate glass is not toxic; it is a safe type of glass. It is used in making many types of products such as cookware and lab equipment.
There could be several rocks used in the making of glass, but the main constituent material used in making glass is quartz. The rock which is used most for supplying the quartz used in glass making is sandstone.
Diamond is used to cut glass, since it is harder than glass.
The main ingredients used in making paper are wood and bleach. These ingredients create the paper the way you see it today.
