RIKYU Cast Iron Tea PotTetsubin or Cast Iron Tea Pots were first used throughout Japan as kettles to boil water over an open fire and usually hung above a hearth to also provide heat and humidity in cold weather. In the mid-19th century as infused teas became popular, brewing and serving the tea to friends and family in a Tetsubin also became very popular. This beautifully crafted RIKYU Cast Iron Tea Pot holds 32 fluid ounces and has a removable stainless steel tea strainer inside. It measures approximately 15" in diameter and is 4 inches in height. The inside is coated with a black enamel.
