The Gauntlets of goldsmithing are one of three possible rewards from the Family Crest quest. They are obtained by taking the Steel gauntlets to the Avan Fitzharmon at the entrance to the Al Kharid mine. Wearing them while smelting gold bars at a furnace will give 33.5 smithing experience per bar (compared to 22.5 experience without gauntlets). Gauntlets of goldsmithing do not work with Superheat Item.
