The pear-shaped, green-green tea, about 13 inches high, bears the marks of Emperor Qianlong, who ruled China from 1736 to 1795, according to Mediafax.
The object, which has a peach and a pencil on the lid, was sold in just ten minutes. The Duke's Auctioneers auction house in Dorchester rated the teapot at between £ 1,000 and £ 2,000, but the item was eventually sold for £ 1,040,000.
The tea was found during a routine visit to the city of Dorset and later generated the interest of "hundreds of collectors and merchants" in an exhibition.
The small kettle, which has a rather damaged lid, received applause after the sale was announced during the auction.
