* Only 20 kg of [[fuel]] is needed at a time; any more is unnecessary. QL of fuel does not seem to affect burning time.
* Put items in [[cauldron|cauldrons]] or [[backpack|backpacks]] inside the forge to allow it to hold more items.
* A forge will hold 7 8 cauldrons.
* A forge will hold at most 28 ore.
* Items that can be [[Fuel|burned]] like [[tar]] or wooden items will take damage in forges once they are almost searing hot. If the item can be repaired, it will lose QL but show no damage.
