A Pottery Oven (also known as a kiln) is used in crafting clay items that have been moulded from soft clay on a Potter's Wheel or with a mould. With the relevant Crafting level the player finishes the unfired versions of clay items, gaining Crafting experience and making the items usable.
The player places the unfired clay item in the oven, waits for a few seconds, then removes the fired clay object. There is, however, a small chance that the unfired items may be burnt in the pottery oven. The probability of burning pottery decreases with increasing Crafting level.
Free players can finish unfired bowls, pie dishes, and pots, while members can also fire pot lids and plant pots.
It would be useful to note that pottery cannot be fired in a furnace, and ores (for example, iron ore) cannot be smelted in a pottery oven.
