A player can obtain this item by placing a full kettle on a range and then removing the kettle from the range. Requiring level 20 Cooking, players can use a hot kettle with a teapot with leaves in order to make a pot of tea and gain 52 experience. Complete directions on how to make tea can be found here.
Note: If a player leaves the house in any way, then this item will disappear from their inventory.
