A Strong cooking urn can be created at 51 Crafting. It is used with the Cooking skill to help with gaining experience.
The urn is filled when the player has earned 5,250 Cooking xp with the urn in inventory. Once the strong cooking urn is full, it becomes a strong cooking urn (full) and can be teleported to Ernie for 1,050 Cooking experience.
All cooking urns give you 20% more experience per cooked food item.
A strong cooking urn is crafted from two pieces of soft clay. Use a pottery wheel and select "cooking urns" from the drop down menu. Then add a fire rune to finish the urn.
