Used. This bag offers 27 additional coal slots and is useful for both mining and forging as it allows players to increase the coal ores carried per trip. It doubles the number of bars per inventory you can have.
It cannot be traded or dropped, but can be destroyed when empty. Players can sell their Coalsack back to Percy for 80% of their original cost in gold nuggets.
The Coal Sack was a reward that could be purchased from the Rewards Vendor for 4,000 Dungeoneering Tokens.
Requirements for the Blast Furnace
If you’re not making gold bars that don’t require coal, you should also get a Coalsack. This bag is a reward from the Motherlode Mine. Without the Coalsack you halve the experience/money rates.
Gold Nuggets are obtained in the Motherlode Mine by searching the sack after cleaning the pay-dirt at a rate of 2.74% per pay-dirt (expected value: 1 nugget per 36, 5 pay-dirt) , regardless of the mining level. They can be exchanged for various rewards in Prospector Percy’s Nugget Shop.
If your Forge level is below 60, you must pay the Furnace Foreman every 10 real-time minutes before you can continue using the Forge. That’s 2,500 gold for every 10 minutes and that can add up quickly, even with the profits you make from selling the finished bars.
Players must be at least Mining Level 30 to mine in the lower tier and Mining Level 72 (cannot be boosted) for the upper tier. In addition to this upper tier requirement, players must pay Prospector Percy a one-time fee of 100 gold nuggets.
To store higher tier ores, you must own an ore chest of that tier. For example, to store 100 mithril ores, you need at least one mithril ore box. If you have an Adamant Ore Crate with you, you can store 100 Mithril Ores, 100 Adamant Ores, and 100 Lower Level Adamant Ores.
Blast Furnaces are much more effective when it comes to smelting ores. They can melt twice as fast as a normal Furnace, which can be extremely useful when crafting fresh gear in emergencies like PvP or when being pursued by an enemy entity.
There are 15 Blast Furnace worlds in Old School RuneScape, all of which make soloing the Blast Furnace easy as there are five different gnomes – Dumpy, Stumpy, Pumpy, Numpty and Thumpy – operating the Blast Furnace mechanic of the blast furnace, so the player only needs to focus on directing the ores to the conveyor belt.
Instead, the main use of gold bars is to craft jewelry with the trade skill. In order to process gold bars into jewelry, players must use a gold bar in a furnace of the correct shape in their inventory. If players want to craft jewelry with inlaid gems, they must also have the corresponding cut gems in their inventory.
Ice Gloves are required to catch Hell Eels in Mor Ul Rek. They can also be used to collect hot rods from the blast furnace without having to use a bucket of water.
If you are attempting to craft Smoothstone for a Blast Furnace (and later for Redstone items), you can craft the required three Smoothstone using your normal Blast Furnace, and then simply switch to the Cobblestone and Smoothstone smelting, to save time.
Superior Mining Gloves are a pair of gloves purchased from Belona’s Mining Guild Mineral Exchange for 120 Unidentified Minerals. They are lost upon death. By speaking to Belona with these gloves and the Mining Gloves, players can pay her 60 unidentified minerals to combine them into a pair of professional mining gloves.
