What is heat-resistant glass and how is it made?
Heat-resistant glass, also known as tempered glass or toughened glass, is a type of glass that is designed to withstand high temperatures and thermal stress. It is made by subjecting the glass to a process called thermal tempering, where the glass is heated to a high temperature and then rapidly cooled using a process called quenching. This process causes the glass to become more dense and rigid, allowing it to resist thermal shock and breakage.
The manufacturing process of heat-resistant glass involves several stages, including cutting, grinding, and polishing. The glass is first cut to the desired size and shape, and then ground and polished to remove any sharp edges or imperfections. The glass is then washed and dried to remove any dirt or debris, and then subjected to the thermal tempering process.
