Very rare early Shekwan unconventionally shaped Leys jar or censer with Jun type flambé glaze, circa late Ming to early Qing. Personally I think this is Ming based on the shallow yet wide footrim and similarity in shape to some Ming celadons I have seen, but will guarantee this to be early Qing, i.e. Kangxi/Yongzheng/Qianlong reigns. There are some firing flaws on the footrim where the piece was pulled from the kiln and bits of the foot came off, bubble bursts inside at the bottom and a spot on the mouthrim where some glaze came off and slid down the side which may be seen enlargements. The last enlargement is from a similarly dated piece (Ming/Qing) exhibited in Hong Kong, 1979 D: 12cm/4.8in and 10cm/3.9in.
