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.
== Notes ==
* The iron can be combined into one lump as only the amount required is used. However* Iron lumps of 1kg or more, this but less than 2kg result in 0.8kg steel lumps while larger iron lumps will result in only produce 0.4kg steel lumps while still using up the charcoal.
* The [[quality]] of the charcoal affects the success chance as well as the likelihood the lump will be high quality. It would be wise to not risk wasting high quality iron on poor charcoal unless you have a lot of it.
* The quality of the iron lump caps the quality of the steel lump.
*A failed attempt uses up the charcoal and 0.4kg of iron, and results in a 0.4kg iron scrap.
* Only the charcoal needs to be glowing hot.
