Blacksmith
A forge is a special type of oven that is used for metalworking. Using a forge to change metal is called "forging". Forging is one of the oldest forms of metal working. To be shaped with a hammer, iron must be very hot. Hot iron becomes cold very quickly when it is taken out of the forge. A blacksmith only has a short time to hammer a piece of iron before it must be put back in the fire to become hot again.
