6 Common Copper Forging Mistakes and How to Avoid Them

Copper work-hardens as it's forged, meaning it becomes harder and more brittle. Annealing (heating and cooling the metal) is necessary to restore its softness and malleability. How to avoid it: Anneal the copper regularly during the forging process. Heat the metal evenly to a dull red color, then let it cool slowly in air or in a bed of ashes
