:* The [[quality]] level of a forge is a factor in both how long it stays lit for and how long it takes to heat up items. Example: a 40[[QL]] forge will take 20 minutes to get iron lumps glowing (also depends on quality of lumps).
:* A 70 [[quality]] level forge burns for 115 minutes with 20kg of [[peat]] set to burn in it.
:* If using [[wood scrap]] as [[fuel]] only burn 20[[kg]] 20kg at a time. A 40QL forge will last for approximately 40 minutes before it needs refueling (more than 20kg does not seem to effect how long the forge lasts at any QL).
:* A forge will hold 28 [[ore]] at most. However, using a [[cauldron]] allows the forge to hold more things.
:* [[Tar]] and other fuel sources can also be used; some burn better than others. See [[fuel]] for more info.
