anneal

When you anneal metal or glass, you heat it and then cool it in order to make it less brittle and more malleable.

Metallurgists — engineers who specialize in the properties and uses of metals — have to know a variety of methods used to anneal different kinds of metals. You can also anneal glass, to make it stronger and to help keep it from shattering.
