To prevent glass from breaking, first put a spoon before pouring hot liquid

Abe V Rotor

Sudden heat may cause glass to break. To cushion this effect, the metal spoon absorbs heat faster than glass. In fact it attains higher temperature than glass or porcelain (china) does.

This principle is also applied when cooking meat. Meat becomes tender in a shorter time by putting spoon or fork in the cooking pot. Metal absorbs more heat that elevates the temperature of boiling water, which normally remains at 100 degrees centigrade (Celsius).
