No, mobile tempered glass is not made using a glass tempering furnace. Instead, most mobile screens are made from chemically strengthened glass. Unlike tempered glass, which is heat-treated in a furnace, chemically strengthened glass undergoes an ion exchange process in a chemical bath, making it up to six to eight times stronger than float glass. However, it is not considered safety glass, as it shatters into long, sharp splinters similar to float glass when broken.
Chemically strengthened glass is commonly used in electronic display products like monitors, televisions, tablets, and mobile phones for screen protection.
In contrast, thermally tempered glass, produced in a glass tempering furnace, is typically used in safety applications, such as car windows, curtain walls, facade windows, indoor partitions, furniture, and household appliances, because it shatters into small, blunt pieces.
