To toughen glass, start by cutting it to the desired size and shape. Then, clean the glass thoroughly to remove any contaminants. Next, heat the glass uniformly in a furnace to a temperature of around 600-620°C (1112-1148°F) until it becomes pliable. Finally, rapidly cool the glass using a process called quenching, which increases its strength and makes it more resistant to thermal and mechanical stress.
