The coal fly ash powder is classified as class C and class F type on the basis of coal origination (types of coal used) and chemical composition (Fauzi et al., 2016). Class C fly ash refers to coal fly ash powder which is derived from lignite and sub-bituminous coals and includes more than 15% calcium (Ca).

During the coal combustion, two types of ashes are generated, i.e., FA (fine particle size) and bottom ash (coarser particle size). FA is used in place of kaolin clay up to 10 wt.% for the insulation refractory bricks fabrication and bottom ash (10 wt.%) is used as a replacement of chamote in the composition of commercial bricks.

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.
