Chinese lidless wine pot said to be named after the Honorable Mrs. Cadogan who brought a Chinese example to Britain and mystified her guests because there was no apparent means to fill the pot, sometimes referred to as a "puzzle pot". The pot is filled when held upside down, through a hole in the base leading to a tube going upward inside the pot to within an inch of the top.
Commonly found in the shape of a peach and in a combination of Celadon green and underglaze red, dating to around the Guangxu period. Rare blue and white examples in the shape also of a peach, occur from the mid decades of the 17th century. Later examples occurs throughout the 20th century.
This shape is known in China as an 'upside down filling wine pot', dao guan hu.
