Glass is made of the mixture of ___________.

Option C

Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. Firstly the glass was manufactured in Egypt. Ordinary glass is manufactured by the composition of various substances like silica, bleaching powder, oxides of alkaline metals, calcium oxide (lime) etc. Firstly the glass was manufactured in Egypt. Basically glass is the homogenous mixture of the silicates of various alkaline metals of non-crystalline and transparent or less transparent substances.

Ordinary glass is manufactured by the composition of various substances like silica, bleaching powder, oxides of alkaline metals, calcium oxide (lime) etc. These constituents of the glass are transformed into fine micro powder and after fusing these are melted into the furnaces at moderate temperature and ordinary glass is prepared by a suitable cooling mechanism of the molten or liquid glass. Thus ordinary glass is a non-crystalline substance of ultra cooled liquid glass.
