Internal stresses in glass arise when different parts cool at different rates. To remove them, you heat the glass to its (typically 450–550 °C for soda-lime glass, depending on composition). At this temperature, the glass is still solid but soft enough for atoms/molecules to rearrange and relieve stress. heat glass to take out internal stresses

Heating glass to relieve internal stresses is a process known as thermal annealing or stress relief. This process involves heating the glass to a specific temperature, typically around 500°C to 600°C, and then cooling it slowly and carefully to prevent new stresses from forming. The cooling process of glass is known as annealing

To remove stress, you must first bring the glass up to its annealing temperature. For most soda-lime glass (common bottles and windows), this is roughly . Borosilicate glass (Pyrex) requires a higher range, around 1040°F to 1060°F . Due to the brittle nature
