The molten glass spreads onto the surface of the metal and produces a high quality, consistently level sheet of glass that is later cut into required sizes. This method gives the glass uniform thickness and a very flat surface. The glass manufactured thus is devoid of waves or distortion. This technique can continuously produce glass 24/7.

To make clear glass, a special sand called silica sand is used. This fine white sand is needed because it is very pure and does not contain other unwanted chemicals. It is "washed" to remove as many impurities as possible, as impurities can adversely affect the clarity and color of the glass. Next ingredient: soda ash.

Wipe the glass residue once more before moving onto the finer sandpaper. The glass will look milky at this stage, but it should be smooth and deep scratches should have been sanded away. 3 – Achieve a Smooth, HighQuality Finish. The final stage is the polishing process – this is what will make your glass surface crystal clear.
