The Heavy Furnace is an improved version of the Furnace. It takes 25 ores (or 5 quartz, fire quartz, etc.) and 3 Coal to run it.
It saves 40% Coal in comparison to normal Furnaces. Additionally around half the time an extra bar is produced, when this happens 50% of the Coal and one sixth of the ore is saved in comparison to normal Furnaces.
Smelting
To smelt any ore, equip it and activate the furnace while there is Coal in inventory. Three units of Coal are required for each smelting operation, regardless of the material or duration. Extra bars might be produced.
