Gold bar

A Gold bar can be created through the use of Smithing and requires 40 to smelt. This is done by using gold ore with a furnace or casting Superheat Item on a gold ore which will grant you 22 Smithing experience and 173 Magic experience.

Gold bars are used to create various jewellery with the Crafting skill. To craft jewellery the player must use a gold bar with a furnace along with its respective mould and potentially any cut gem in the inventory.

A 'perfect' gold bar looks just like a common gold bar, but cannot be created with Smithing and cannot be used for Crafting, and has a net worth of 100k exactly.
