From sand to flat glass - Glass for Europe
WebThe raw materials that float glass is made up of are: SiO2 – Silica Sand. Na2O – Sodium Oxide from Soda Ash. MgO – Dolomite. Al2O3 – Feldspar. The above raw materials primarily mixed in batch helps to make clear glass. If certain metal oxides are mixed to this batch they impart colors to the glass giving it a body tint. WebThe manufacturing process of glass can be categorized into four major steps: batch mixing, furnace charging, melting and glass forming. Batch mixing is the process of blending raw materials for the production of different glass products. The selection of raw materials depends on the type (color, texture) of product to be produced. WebIn a very simplified way, glass-making is a melting and fusion process of raw materials typically consisting of: sand, soda ash (sodium carbonate), dolomite, limestone and salt cake (sodium sulfate). The raw materials are mixed in a batch process, then fed together with waste glass into a furnace where it is heated to approximately 1350 °C. raychem bird guard
