Chinese Bone Pottey (Southern song) or 15th centurty?
(Upstate, NY 12442)
I think my previous post did not go through.
This item was described as bone pottery, Southern Song 12-13th century. I found on the Internet very similar item? also with a delicate carving inside. This carving looks like a watermark on a paper. This bone pottery technology was introduced in 1450's.
I have a pair. Do you know something about items like this? How about rarity?
I am placing a link to Flickr to see more details.
