How is glass formed

Melting and Refining In order to make clear glass , the right set of raw materials is required. These ingredients are mixed in the right proportion, and the entire batch is flown into a furnace heated to degree Celsius. In order to impart colour to the glass, certain metal oxides are also mixed in the batch.

Float bath The molten material from the furnace flows into the float bath which consists of a mirror-like surface made from molten tin. This material enters the bath at degree Celsius and leaves the bath at around degree Celsius. For example, other chemicals are added to make color glass. Or boron oxide is added to make an oven-proof glass. Shelving offers convenient and functional storage, but if you want it to also enhance your space, we recommend installing custom glass shelves into your home.

The exact composition of glass may vary to meet specific applications requirements but the most commonly use type of glass, soda-lime glass, is made of silica sand, soda ash, limestone, dolomite and glass cullets recycled glass. Additional materials such as iron oxide or cobalt can be added to the mix to give a green or blue colour to the glass.

The sand commonly used to make glass is comprised of small grains of quartz crystals, made up of molecules of silicon dioxide, which is also known as silica. When those molecules are heated to high enough temperatures, the sand melts and loses its crystalline structure, and as it cools it gains an entirely different structure. That structure, on a molecular level, is somewhere in between a liquid and a solid.

This in-between state is known as an amorphous solid, which means it has some of the crystalline structure of a solid coupled with the molecular randomness of a liquid.

Depending on the sand mixture, glass can have a variety of properties. To strengthen glass, manufacturers can use thermal tempering to heat and cool it rapidly.
