A Cracked smelting urn can be created at 4 Crafting and is used with the Smithing skill to help with gaining experience. It can be constructed by using 2 soft clay on a pottery wheel to create a cracked smelting urn (unf). After firing it in a pottery oven, a fire rune must be used on the cracked smelting urn (nr) to enable it to collect 'scraps of metal'. The urn is filled when the player has earned 200 Smithing xp with the urn in inventory. To fill the urn, players must smelt bars in the furnace with the urn in their inventory. Smithing items from the bar does not fill the urn. Once the cracked smelting urn is full, it becomes a cracked smelting urn (full) and can be teleported to Ernie for 40 Smithing experience.
Using Superheat Item does fill an urn. Using the blast furnace does not fill the urn. If smelting two bars at once in the Edgeville furnace, the urn only fills with xp from the first bar that is made. The second does not count.
