A delightful shape rise with thinly potted in definitely unusual double gourd and rare shape, divided into octagonal side included foot, body and mouth rim, covered overall with green grays celadon tone, thinly foot rim with dark brown clay. This clay has been described as the "finest and purest of the superior clays" The Japanese scholar Mr. Yamato Yoneuchi has discovered kiln equipment and pot sherds at North East foot of Phonenix Hill near Hangzhou; many of these sherds were made of the grayish body material. This nice and rare vase showing some special characteristics of Guan ware are it's "purple mouth" and "iron foot" Because the glaze tended to run down the sides of the vessel during and after glazing, the iron-containing body material of some Guan wares, especially around mouth rim and adjacent rises areas, would be more visible and therefore darker in appearance. The mouth rim area thus became reddish-brown in appearance. The term of 'iron foot" refers to the fact that the ring foot was iron-black in colour. The glaze is fine and very glossy and the condition is very good, except two minor tiny flake chip to inner rim, and the other crack is appear to the body when we touch that area, it's mean these kind of crack only appear to an old pieces or at least old manufactures.
