Strong smelting urn (full)

The strong smelting urn (full) is an item made by filling a strong smelting urn while smelting or superheating bars. It can be teleported to Ernie by clicking it, giving 250 Smithing experience. A full urn can also be given to Ernie manually by using the item on him, or through a chat option while having a full urn in the inventory.

Players may only have 10 full urns at a time without teleporting them. If players have more than ten urns in their bank, inventory, and Beast of Burden combined, then they will not automatically fill up the 11th.
