In the float glass process, a continuous strip of molten glass, heated to more than 1000 degrees Centigrade is poured from a furnace on to a large shallow bath of molten metal, usually tin. The glass floats and cools on the tin and spreads out to form a flat surface. The speed at which the controlling glass ribbon is drawn determines the ...

Next, in order to remove the internal stresses built up in glass, a process called annealing is done. This process allows the glass ribbon to pass through a layer which eliminates any stresses on the glass surface and gradually cools it to give it its final hardened form. This makes it easier to cut the glass and shape it accordingly.

Properties of Glass Materials. In general, glass is a hard and brittle substance that is usually transparent or translucent. It may be comprised of a fusion of sand, soda, lime, or other materials. The most common glass forming process heats the raw materials until they become molten liquid, then rapidly cools the material to create hardened glass.

When glass is recycled, it can be melted down and reformed into new products without the need for the energy-intensive process of mining and refining new raw materials. In fact, it is estimated that recycling one ton of glass saves approximately 1.2 tons of raw materials and reduces energy consumption by 15-20%.
