Portable forge is an item won on Treasure Hunter that acts as both an anvil and furnace when deployed, but not as a barbarian anvil. Using the forge provides 10% additional experience to most smithing actions (does not provide extra experience when smelting corrupted ore). The furnace provides a 5% chance of providing an extra bar (including bane ore) while the anvil has a 10% chance per bar of saving each of the bars in use (this includes protean bars). All bars saved are deposited in the bank whether your inventory is full or not. When this happens, the following shows up in the chatbox:
You managed to make an extra bar from your ore in this exceptional furnace! It has been sent directly to your bank. or The portable anvil saved your bar!

It can be placed anywhere that you can light a fire and is both visible to and usable by all other players. It cannot be placed in a Player-owned house. It cannot be placed in an ongoing fight of Vorago, regardless of being able to light a fire there. It vanishes after placed for 5 minutes; though you can add more forges to the already deployed forge which adds more time with a maximum of 60 minutes. Although you can still use the forge after it disappears if you have clicked on it, you will no longer receive any of the benefits of the forge. When the Forge disappears, if you are Smithing, you will be stopped unless smelting corrupted ore. However, this may be an oversight.

Right-click configure allows players to choose smelting or smithing as the left-click option of portable forges.

Jewellery that requires a furnace can only be made on a portable forge and not a portable crafter. Additionally, the forge does not provide any of the other benefits for making jewellery.

You can use another player's portable forge and receive the same benefits. A popular place to do this is in world 2 at the bank in Burthorpe or at the Combat Academy in Lumbridge for members. This is particularly useful for training, as players like to use pulse cores at this location, giving a 2% bonus to any experience earned for 10 minutes for all players nearby. This can stack up to 10% and will combine with the forge's bonus experience rate of 10%. For free-to-play players, world 3 usually finds a portable smith at the Combat Academy, next to the bank chest.

Profitability

Depending on Grand Exchange prices, portable forges may yield more profit per hour compared to other methods like Superheat Item, the Blast Furnace, or regular anvils.

The supplies for 1,000 rune bars (1,000 runite ores, 8,000 coal and 11 portable forges) cost 1,419,000+896,000+. The forge would produce a total of 1,053 rune bars, worth 3,143,205 coins, with a profit/loss of 3,143,205−1,419,000−896,000-, or an hourly profit/loss (1200 ores smelted per hour) of (3,143,205−1,419,000−896,000-)/(1,000/1,200).

Used purely for smithing bars for experience, the forge can significantly reduce costs. 1,000 rune bars smithed into platelegs and sold on the Grand Exchange would require 13 forges and save 111 bars, resulting in a profit/loss of 13,690,740−2,985,000-, or an hourly profit/loss of (13,690,740−2,985,000-)/1,111*3,105 (3105 bars smithed per hour) or (13,690,740−2,985,000-)/(370*3*75) per experience, and 232,875 experience per hour.

The above calculations do not take the effects of wasteless smithing into consideration.

If a player decides to buy the ores (1,000 runite ores, 8,000 coal and 29 portable forges), smelt the bars and process them into platelegs the forges would produce an extra 175 rune bars. This results in a total profit/loss of 14,467,782−1,419,000−896,000-, or an hourly profit/loss of (14,467,782−1,419,000−896,000-)/(1,000/759+1,175/3,105). Additionally high alchemising the resulting 391 platelegs would change the total profit/loss to 391*38,400−158,355−1,419,000−896,000- and the hourly profit/loss to (391*38,400−158,355−1,419,000−896,000-)/(1,000/759+1,175/3,105+391/1,200).

Trivia

• It is possible for wasteless smithing to activate together with the forge's bar saving ability.
• On 15 June 2015, a bug was introduced that allowed players to use the portable forges in order to block players, preventing them from moving. This has since been fixed.
• As of 6 June 2016, checking the duration of a portable skill station will no longer interrupt skilling actions. This action can also be done remotely.
