Smithing

Smithing is considered as one of the hardest and most expensive skills, because the xp rates are low and the bars require a lot of time to smelt and gather. The Smithing skill uses the ores obtained with the Mining skill to smelt bars and smith items out of them on an anvil. For nearly every bar you need several ores to refine it and for nearly every item you need multiple bars, thus the Smithing skill requires high amounts of ores to advance.

Smelting

To smelt bars you need ores obtained with the Mining skill. You use one of the ores on a Furnace to start smelting bars.
Be aware that for bronze bars you only need 1 tin ore and the rest copper ores, or vice versa, to create all bronze bars. Also the iron ores will turn into iron bars with a success rate of 100%.
All bars can also be smelted with the Superheat spell on the Normal spellbook. If players use the Superheat spell they need no smithing requirements to smelt the bars, but they will still gain the same smithing experience!

Smithing

To start smithing you need bars and a Hammer bought from the General store. Find an anvil, for example in Varrock, use the bar on the anvil and an interface will appear asking you what item you'd like to smith.

Below is a Smithing experience table of the amount of Smithing experience that you can gain from every bar you smith and the minimum level you need for smithing it.

Bar	Smithing level	Smithing XP
Bronze bar	1	50
Iron bar	15	90
Steel bar	30	130
Mithril bar	55	170
Adamant bar	70	215
Rune bar	55	280

Here is a full table of what item you can smith on what level and how many bars they require to make. Smithing items that require more bars at the same time will speed up smithing a full inventory of bars, but smithing arrowheads or bolts might be more profitable. A full inventory of arrowheads takes a lot longer to make than a full inventory of platebodies.
