Blast Furnace

The Blast Furnace can be used with the blast_furnace:true option in the /smelt command. For example /smelt name:Gold bar blast furnace:true
The Blast Furnace costs 216,000 gp/hr to use, or 72,000 gp/hr if your minion is an ironman.
Smelting bars at the blast furnace is faster than smelting bars normally, and the amount of coal needed to smelt bars is halved.
