Pay-to-play Smithing training

Quests

 * The Knight's Sword grants 12,725 Smithing XP.  You can do this quest for 1-29 Smithing.

Level 1- 15
To reach level 15 smithing, you will need to smelt and smith 128 bronze bars.

Level 15-35
At level 15 you can smelt iron. Iron is one of the worst ways to train smithing because when smelting them you only get an iron bar 50% of the time, unless you are wearing a ring of forging or superheating.

Smelting
Players can smelt ores into bars at a furnace for Smithing XP. Alternatively, players can superheat which allows players to smelt at a bank or at a mine for the cost of 1 nature rune and 4 fire runes. Players only have a 50% chance of smelting iron ore at a furnace unless they use a ring of forging.

Some players turn steel bars into cannonballs at a furnace after they have completed the quest Dwarf Cannon.

Players who have completed Family Crest can use Goldsmith gauntlets to increase the XP for smithing gold ore from 25 XP to 56.2 XP. This is one of the fastest ways to gain Smithing XP.

Smithing
Players can choose to smith bars into armour and other metal items at an anvil. Traditionally the best things to smith are iron knives and platebodys, depending on whether the player wants fast xp or profit.

Blast Furnace
Players can play the minigame Blast Furnace to smelt ores using half the required amount of coal.

It is advised to use the "Osrs Bf" cc to teleport to Blast Furnace and to get more bars/hour.

Furnaces
