Pots are containers that function much like barrels, but can be made from other materials. They can be made from ceramic at a kiln, glass at a glass furnace, stone by a stone crafter at a craftsdwarf's workshop, or from wood at a craftsdwarf's workshop. Pots made from stone, stoneware, glass, wood, porcelain, or glazed earthenware are water-tight and can be used to store liquids, and even for brewing. Unglazed earthenware can only be used for storing dry items. Pots are stored in the Large Pots/Food Storage section of the Furniture stockpile. Pots are visible on the haul-for-trade screen under Tools section.
Workshops that require a barrel for construction cannot use a pot instead.
