How Glass is Made

Glass is made by sand that contains of silica (SiO2). Silica is combined with soda (sodium bicarbonates) to make the silica’s viscosity and fusion temperature become lower. Then it is combined with limestone as a stabilizer. First, the three combined material are burned with furnace. Second, after it become a liquid, it is distributed into two different process, to be a plate glass and a bottle glass. Next, in plate glass process, glass is pressed by roller while in bottle glass process, glass is shaped by removable mould.
