Furnace



A Furnace is an interactive scenery object used in Smithing and Crafting.

In Smithing it is used for the process of smelting, that is separating out impurities in ores from the metal to make metal bars. Smelting different ores requires different Smithing levels. It may also require more than one type of ore, and varying amounts of coal in some cases.

Players with Level 43 Magic may choose to use Superheat Item instead of furnaces for smelting, earning both Magic and Smithing experience, although this will prove costly as it requires 1 nature rune per bar (if you have a Staff of fire equipped). Superheat Item does not work for jewellery.

A furnace is also needed for some Crafting purposes. With the appropriate mould and Crafting level required, players can use the furnace to craft gold bars into jewellery (e.g. rings, necklaces, bracelets, amulets) with or without gems. Players can also craft silver bars into holy symbols, tiaras, unholy symbols, or lightning rods depending on their Crafting level and the mould they have in their inventory. Players may also make molten glass by smelting soda ash and a bucket of sand.
