Detailed explanation-1: -The most familiar type of glass is ‘silicate glass’. It is also the oldest type of glass that mankind has seen. The main component of glass is silica (silicon dioxide) which is also present in the sand. Today, many silica-based glass types exist with different properties.
Detailed explanation-2: -Glass is made of the mixture of sand and silicates.
Detailed explanation-3: -The chemical process of creating glass is undergone by heating quartz sand, also known as silica sand, to temperatures above 3, 090 degrees Fahrenheit until it melts into a clear liquid. Once the sand is in liquid form, it is cooled and undergoes a transformation that doesn’t allow it to fully turn to a solid.
