The process of making toughened glass involves heating the glass to a very high temperature, typically around 620°C (1148°F), and then rapidly cooling it using a special cooling process called quenching. This causes the glass to cool down quickly, which creates a strong compressive stress on the surface of the glass while leaving the core in a tensile stress state.
