Spadeful of coke

A Spadeful of coke is an item used within the Blast Furnace minigame. Players may use the Spadeful of coke to refuel the Furnace Stove. Doing so will grant the player 5 Firemaking experience. Eventually, if a player keeps loading in the coke, they will receive a message in the chatbox saying that the furnace is full, after which they will have to move on to another task or wait until it requires more fuel.
