Superheat Item is a utility spell available in the standard spellbook. It requires level 43 Magic to cast, and grants 53 Magic experience per cast. It allows players to smelt ore into bars without a furnace. It cannot be cast on noted ore.

Casting the spell on a piece of ore in the player's inventory requires the same Smithing level as smelting the bar at a furnace, along with the appropriate amount of coal. Each bar made yields the same amount of Smithing experience as would be gained from smelting the bar at a furnace. 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 or tome of fire is used, it is more profitable to use a ring of forging by 128.91 coins per bar.

Casting Superheat Item does work in conjunction with smithing catalyst, providing the catalyst's usual effects of halving coal consumption and doubling the experience gain for the ore it was cast on.

Uses

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.

Superheat Item can also be used as a Magic training method for both Free-to-play and members. When using the Spell you can theoretically get up-to 106,000 Magic Experience an hour, however due to the need of using a bank to store and restock you can expect rates closer to 90,000 - 100,000 experience an hour from efficient Superheat Item casting.
