Republic or later?
I'm worried about not being glazed on the inside.
Usually the foot would be shaved on the inside and outside on an Antique.
That's something new to me. I would think this would be necessary only if the glaze was not well controlled and pooled to the foot.
While this shape did exist, I have doubt about it being found as a private kiln item of the Qianlong dynasty, as the mark indicates. The bottom is also not quite right for that period, I think. And yes, not being glazed is odd. Probably a late 20th century item.
As a rule it is recommended to stay away from monochromes as the provide fewer points of reference for evaluating authenticity and dating. There is no decoration and genuine age and usage signs are more difficult to see.
(It took me about ten years to get to the point where I am now more confident in this respect, but some monochromes even now are difficult to verify.)
I agree, dead bubbles and all.
Thanks for your input Peter.
I know monochromes are hard to date and authenticate but when I find something at a good price, I buy it.
At least can be used as a study piece.
