Wiki's annswer to the question of HOW to anneal copper is totally wrong and backwards. You anneal copper by heating it with propane torch to dull cherry red, then quinching it in water. (the opposite of annealing ferrous metal)

The purpose of annealing copper is to make it soft again.
One purpose is to soften copper spark plug washers on aircraft engines.
