A '''steel lump''' is the result from combining a 2:1 ratio of [[iron lump]] and a [[temperature|glowing hot]] piece of [[charcoal]] to harden the metal. That means for 0.50kg of charcoal you need about 1.00kg of iron lump.
Using steel to create items that can be created with other materials has no effect other than what type of metal you need to improve it with the exception of lamps. Steel lamps produce a different shade of light and may have a unique model.
== Notes ==
* The iron can be combined into one lump as only the amount required is used.
