Ge-type stoneware flower-pot-stand or censer with straight sides, five cloud-shaped feet and five raised bosses on the rim. The flower-pot-stand has a very dark grey body covered in grey glaze with uneven crackle which is reddish-brown on rim and grey in some areas. Where exposed in firing, the body is reddish. There are three large spur marks on the interior. The rim of the foot and the base of the feet are unglazed. Height: 88 mm. Diameter: 199 mm. Diameter: 83 mm (base)

Writers described guan ware as having 紫口鐵足(zikou tiezu ‘purple mouth and iron foot’), referring to the dark purplish-grey body showing through the glaze where it runs thin at the rim and to the ferrous-brown colour of the unglazed foot.
