A decorated mining urn is an urn used with the Mining skill to help gain experience. It can be created at 59 Crafting (granting 95 experience) on a potter's wheel, requiring 2 soft clay to make. It must then be fired in a pottery oven creating a decorated mining urn (nr). The urn must then be activated with an earth rune to become a decorated mining urn (r) before it can be used. Players that do not have the required Crafting level to place the rune in the urn may use the assist system. The urn will become full when the player has earned 3,125 Mining experience with the urn in their inventory.
Once the decorated mining urn is full, it becomes a decorated mining urn (full) and can be teleported to Ernie for 625 Mining experience. Only 10 urns can be full at a time. Once 10 urns are filled, they must be teleported before new urns can be filled.
Extra gems found while mining will not fill the urn, however mining gem rocks will. Mining sandstone and granite also fills up the urn. The juju mining potion's effects don't interrupt the urn's performance - the ore mined and immediately smelted by a stone spirit counts towards filling the urn.
Using a sacred clay pickaxe will not fill up the urn faster. A penance horn will not give double experience when teleporting urns. Mining a shooting star or at the Lava Flow Mine will not fill the urn. If mining multiple ores at once, using either Varrock armour or the reward effect of a shooting star, the urn only fills with experience from the first ore. They are not filled when mining divine tear rocks at the Battle of Lumbridge. However, they are filled when mining in The Empty Throne Room
When a lower levelled mining urn is present in a player's inventory they will take priority over the decorated urn, meaning that any ores requiring lower than level 70 will fill a strong mining urn rather than the decorated. This lower tier priority also applies to cracked, fragile, and plain mining urns.
There are two challenges associated with the urns: creating 70 urns, which counts as a Crafting challenge, and filling 14 urns, which counts as a Mining challenge.
