These 1 litre kettles and warmers are made for use in the 'Gong Fu' tea ceremony, where a constant supply of hot water is needed at the table. This is the most traditional style and comes with a little lamp for burning alcohol. It is made from high quality ceramic and can be used on a gas stove too. It can even be used as a teapot for those seeking volume! These are made in Taiwan where the Gong Fu ceremony has been taken to new heights.
