Glass contains three major categories of constituents - formers, fluxes, and network modifiers. Silicon dioxide (SiO2), or sand, is used as the former and basic constituent with soda ash (Na2CO3) as the flux. Lime (CaCO3) and dolomite (CaCO3MgCO3) are network modifiers that stabilize the chemical properties of the glass.

96 percent silica. Soda-lime glass, since it constitutes 77 percent of total glass production, is discussed here. Soda-lime glass consists of sand, limestone, soda ash, and cullet (broken glass). The manufacture of such glass is in four phases: (1) preparation of raw material, (2) melting in a furnace, (3) forming and (4) finishing.

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.

Both lime and limestone (calcium carbonate) are essential components in glassmaking, as calcium is used as a stabiliser that improves the quality and physical appearance of the glass. Quicklime (calcium oxide) can also be used where higher efficiencies and outputs are required during glass manufacturing. Contact Us. 03303119850.
