Bar

A Bar is a piece of metal that is obtained from smelting ore in the Smithing skill. Bars can be made into armour and weapons by using them with an anvil. Iron bars, silver bars, gold bars and mithril bars can be exchanged for certificates at Draynor Village market, with Miles, or at Zanaris, with Watto, to trade bulk amounts of bars easier and faster.

Types of bars
There are several different types of bars that require different smithing levels to make. Smelting bars can be done at a furnace by simply using the ore on the furnace while having the required ore in your inventory. When smelting, each ore has a 100% chance of successfully being made into a bar, except Iron ore, which has a 50% chance of successfully making a bar when using a furnace. Using the spell Superheat item has a 100% success rate on iron ore. Failure to smelt an iron bar will result in the loss of the iron ore and no experience granted.
