Two different cast iron kettles can be purchased at Home Depot and NorthlineExpress.com. The kettle available at Home Depot is 3 quarts, while the kettle available at NorthlineExpress.com is 5 quarts. Both kettles are for use on a wood stove.
Cast iron kettles provides humidity to a room using a fireplace or wood stove for heat. The heat from the wood causes the air to become dry, which leads to problems, such as headaches, sore throats or dry skin. Besides alleviating these symptoms, the cast iron kettle becomes an air freshener when potpourri or cinnamon sticks are added. Both kettles are black and have a chrome handle that stays cool even when the cast iron is hot.
