To create an [[iron]] lump you'll need 20 kg of [[iron ore]] and a heat source (could be a [[forge]], [[stone oven]] or a [[campfire]]). You must put the iron ore into the heat source and wait until it is [[glowing]] from heat, soon after which it will turn into a 1kg iron lump. The higher [[quality]] the heat source and ore, the faster the ore heats up and turns into lumps.
