Superheat Item is a non-combat Magic spell that smelts ore into bars without a furnace.

It is cast on an ore in the inventory, requiring the Smithing level to smelt that ore into a bar. It cannot be cast on noted ore. This also requires the same amount of coal as standard smelting. Each cast yields 53 Magic experience along with Smithing experience from the bar that is smelted. The experience-boosting effect of the goldsmith gauntlets or Smithing cape is applied when casting Superheat Item.

Casting Superheat Item on iron ore with at least two coal always produces a steel bar, otherwise it produces an iron bar with a 100% chance of success. This is comparable to a ring of forging, used to increase the furnace smelting rate from 50% to 100%. Assuming a staff of fire is used, it is more profitable to use a ring of forging by 84.43 coins per bar.

Casting Superheat Item with Smithing Catalyst in your inventory will consume it. As well as provide the effects of it including halving coal consumption as well as doubling the xp gain for the ore it was used on.

    Uses[edit | edit source]

    Superheat Item can be used to extend Mining trips by mining coal and the ore. Bars also weigh less than ore. For this method, it is recommended to equip a staff of fire, with a pickaxe and nature runes. Ore can also be brought to the mine to superheat while mining only coal. Without a coal bag, Superheat Item can save time transporting coal from the coal trucks, which will also requires ores to use. Repeatedly withdraw coal and cast Superheat Item.

    It can also be useful when killing creatures that drop the ores and coal to save inventory space or earn Smithing and Magic experience while fighting.
