The coal bag is a reward purchasable from Prospector Percy's Nugget Shop for 100 golden nuggets. Only one coal bag may be in the player's possession at any time.

The coal bag holds up to 27 pieces of coal (36 if a smithing cape is equipped). When smelting or superheating, coal in the bag will be used after the coal in the inventory. It is refillable just like the rune essence pouch, though it does not degrade.

This item cannot be traded or dropped but it can be destroyed. The bag must be empty to be destroyed; otherwise, the player receives a notification regarding the coal still left inside the bag. Mined coal is not automatically stored into the bag. Instead, players must manually use a coal on the bag. When coal in the player's inventory is used on it, all pieces of coal (up to 27) are deposited into the bag.

Those trying to complete the Falador Hard Diary may wish to save their gold nuggets until they obtain 180, complete the task, and then get 80% of their nuggets refunded by turning in the outfit.

You can sell your coal bag back to Percy, returning 80% of its original cost.

Uses

This bag provides an additional 27 coal slots and is useful for both mining and smithing as it allows players to increase coal ores carried per trip. It doubles the amount of bars per inventory you can have.

The first column identifies the type of bar to be made. The second indicates how many pieces of coal should be in each bag. The third represents how many of the primary ore (Iron, Mithril, Adamant, Runite) is required. The fourth column represents how many free inventory slots remain. The fifth column shows how many bars are produced. The last column indicates the experience received from smelting a full load (including coal in the coal bag) of that ore.

Blast Furnace (starting with an empty inventory)

Bar Type	Coal Needed (In Bag+In Inventory=Total)	Primary Ore	# of Free Inventory Spaces	Bar Yield	Smithing Experience
Steel	27 + 0 = 27	27 Iron ore	0	27	472.5
Mithril	27 + 9 = 36	18 Mithril ore	0	18	540
Adamantite	27 + 12 = 39	13 Adamant ore	2	13	487.5
Runite	27 + 13 = 40	10 Runite ore	4	10	500

Other Furnaces (starting with an empty inventory)

Bar Type	Coal Needed (In Bag+In Inventory=Total)	Primary Ore	# of Free Inventory Spaces	Bar Yield	Smithing Experience	Smithing XP without bag
Steel	27 + 9 = 36	18 Iron ore	0	18	315	157.5
Mithril	27 + 13 = 40	10 Mithril ore	4	10	300	150
Adamantite	27 + 15 = 42	7 Adamant ore	5	7	262.5	150
Runite	27 + 21 = 48	6 Runite ore	0	6	300	150

• To make the most use of inventory space the ores should be mixed instead of using just the one type of ore. In example: taking 27 + 20 coal, 6 adamantite ore and 1 mithril ore that way there would be no empty space. This method however takes more clicking.

Superheat Ores (start with nature runes and a fire staff equipped)

Bar Type	Coal Needed (In Bag+In Inventory=Total)	Primary Ore	# of Free Inventory Spaces	Bar Yield	Smithing Experience	Magic Experience
Steel	27 + 7 = 34	17 Iron ore	2	17	297.5	901
Mithril	27 + 13 = 40	10 Mithril ore	3	10	300	530
Adamantite	27 + 15 = 42	7 Adamant ore	4	7	262.5	371
Runite	27 + 13 = 40	5 Runite ore	7	5	250	265

WARNING

Attempting to use alchemy on the coal bag while having coal inside will convert it, regardless of the fact that using the destroy option does not work.
