Hi Peter, this is an unusual tea pot, if it is a tea pot, it has a very wide mouth, the antique dealer said it was a win pot, the size is 10.8 cm tall, I will post 12 photo's note in photo's 5jpg and 6jpg in 6 it is the sun glare but it is a good photo to see the texture in the glaze, please let me know how old you think it is, thanks.
Here are more photo's to view.
Hi is the last set of photo's, note the red mark is stamped and it is not in my book of marks, at least I could not find one that matched when I did my comparison of marks, thanks for your help.
Both seem to be late Qing to early republic. The mark seems to be private manufacturer or shop mark. I cannot read all of it.
