/**
	Put /obj/smithing_placeholder into a heatsource that is 90% of the melting temperature of that material to heat it up temporarily (spawn 10 seconds)

	If struck by a blunt object (preferably a hammer, but a toolbox can work) enough times before it cools, it will make the object.

	Can then choose to keep striking it to potentially increase its quality, but each time doubles the chance of failure per swing.
