HQ Charcoal

Just a thought, but how about add a HQ charcoal which is required to smelt HQ metal as well as wood - maybe even requiring a large furnace.

Was reading about how iron was made a 1000 odd years ago, they went to massive efforts to make charcoal in order to bung into a furnace to reach iron melting temperatures

I would like to see something that converts Metal frags into HQM like 100 Metal frags -> HQM
