Reducing the Risk of Broken Glass

The purpose of the title above to reduce the risk of broken glass when pouring very hot water. Perhaps we often pour hot water on glass or bowl, sometimes afraid that the glass can not withstand the heat and rupture. Simple, do not pour the water first, if you make coffee, first insert spoon, coffee powder, or sugar. So when the hot water in, heat is not absorbed by the glass, but also share the spoon and coffee grounds. Thank you, I hope useful ...
