What Does Crucible Mean?

A crucible is a vessel made of porcelain, glass, or metal that's used to heat materials to extremely high temperatures.

The word crucible comes from the Latin word "crucibulum," which means "small cross," and was originally used to refer to a vessel that contained the ashes of an executed person. It was later used to describe a container for other things that were destroyed or tested by extreme heat. The term "crucible" was first used in English in the early 1600s and has remained in use ever since.
