The strong mining urn (full) is an item made by filling a strong mining urn while mining rocks. It can be teleported to Ernie by clicking it, giving 400 Miningexperience. Only ten full urns of any type can be held at any one time. Once that number is reached, new urns will not start collecting charges. 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.Full urns can also be teleported automatically by toggling the "Auto teleport current skilling urn when full" option on under skilling options in miscellaneous gameplay settings.
