Is it okay to put boiling water in glass?

Can you put boiling water in a glass?

You can put boiling water in a glass bottle. … A bottle if heated from inside develops tensile stress in the skin that causes it to shatter. By first exposing the outside to heat and warming it up, the outside already expands and so when you pour the hot water inside it causes much less tensile stress in the glass wall.
