An Urn is traditionally used as a container for the ashes of the deceased.
It can be placed as an aesthetic block.
An Urn is crafted by placing a clay block on top of a Turntable and letting it rotate until the Unfired Pottery becomes the shape of an urn, which is after 8 complete turns. You will get 3 Clay Balls back in the process, so the Urn costs 1 Clay Ball total. After that it must by fired in a Kiln.
