"Possibly Song or Jin dynasty judging by the base. Qingbai ware. If the glaze were white I would say Ding ware but not sure with uneven unglazed area below the rim. If it was Ding it would likely not be the Ding kiln. This is excavated. May I ask if you got this already? If it is now in China and you want to export it, I would advise to forget about it. It is risky now..."
I don't think it's worth much, but still... pretty cool.
I did not know that this plate was excavated.
There was a tint on the image because my screen was not calibrated properly. For this reason, I'll add another photo I took with my smartphone to this post. The glaze however still does not look white to me.
So of 9 inexpensive plates only 1 was a replica and 2 were vintage and not antiques. That's a nice outcome in my opinion for someone who knows little about porcelain. I just took some photos of verified pieces and compared them to inexpensive ones from private sellers. I could not have afforded to buy these plates from an accredited dealer.
Update - After the new photo he added this to the conversation:
"'qingbai' is a whitish color with a celadon tint. It is clearly not of the white variation. Certain kilns of the Tang and Song dynasties produced white porcelain which would be called yellow or light gray nowadays, The Chinese still call those off-white variations today 'white' although they are not white in today's sense. The same is the case with other colors. But they are slightly different from the 'qingbai' white.
If you have it already out of China there is no problem. It seems to be prohibited now to even own excavated porcelain in China. I believe they confiscate such items if found.
The yellowish color of the unglazed areas points to ingrained soil. Most items of that period are excavated, although not all do show soil sediment; the likeliness of something that old being handed down until today is small."
"You will not find a pure (snow) white glaze in all of Chinese porcelain before the 20th century. Such a white color is usually a sign that an item is more recent, that is a fake."
