These tongs leave marks on the glass..

What is pure glass?
Glass is a non-crystalline, often transparent amorphous solid, that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass are naturally occurring.
What type of glass is used in commercial buildings?
Tempered glassTempered glass is the most widely used commercial glass and is often required by law. It is stronger than residential glass by four to six times, and is also designed to shatter in small harmless pieces when broken, as opposed to residential glass which breaks into large sharp pieces.
What is the best material to build a skyscraper?
