Ceramic-Glass
Raw materials for Glass manufacturing:
In a batch, 51% of the weight will be Quartz (Silica Sand), 16% is Soda Ash, 13% is Dolomite, 4% of Limestone, 1% Sodium Sulphate + Ingredients for Imparting Colour and 15% of recycled glass waste. Of the above raw materials used for glass manufacturing, the most expensive of the materials used in the batch is soda ash. Though this forms only 16% of weight this accounts for almost 60% of the raw material cost. Glass can be manufactured fully by making use of Quartz or Silica Sand alone. It is being done like that for manufacturing Glass that is used for special applications. The other materials are generally used for simplifying the manufacturing process of glass. To be more specific the soda ash is used for lowering the melting point. While the pure Silica has a melting point of 2300C for manufacturing glass it can be brought down to 1500C by addition of Soda Ash.
