Manufacture of Glass: Step by Step Process

1. Collection of raw materials. The raw materials such as silica (in the form of sand or quartz SiO2), soda ash (Na3CO3), limestone (CaCO3), and cullet (broken glass) are collected separately and mixed in a proper proportion. The fusion of cullet (broken glass) is added to bring down the melting point of the charge.
