Tea bowl age

[peterp]

I wonder if anyone can date this bowl.
This is apparently a so-called Chosen Karatsu (????) tea bowl, made in Karatsu, Kyushu.
'Chosen' was the reign name of Korea during most of the MIng and Qing dynasties. The name is used to designate the black and white style as being Korean, so this would be a Korean style Karatsu bowl. Identification of the origin was mainly possible because of the foot rim type; any information on its possible age would be appreciated.

Hi Peter, the bottom sure looks like Yuan dynasty but in one of my books " The art of Japanese ceramics " there is a bowl from the Fourteenth century called a Temmoku tea bowl from the Seto kilns, if it is authentic it would be very valuable, I have never held one or seen one except in books or museums so I can not tell you much other than it looks old, you should get it looked at by an expert specializing in old Japanse Tea bowls.

Thanks Stan, I'm pretty sure this is Karatsu ware. Took me quite some time to find out but the characteristic protrusion running around the circumference and the black and white glaze helped to find the origin. Not all Karatsu bowls do have the line on the rim. Karatsu ware seem to be mostly rustic wares...without the fine glazes found on items of the larger kilns.
Are there any specialists for such Japanese wares?

Hi Peter, Bonhams has a specialist on Japanese wares, however I never met her, she was in Oregon for a short time viewing items from prospective clients for an upcoming auction, I just missed her and the lady that did look at some of my Japanese was a Chinese specialist so I did not learn anything concerning Japanese wares, but the lady said that they will come to my house and look at some of my items for their auction, that is one way, the best way because you get an expert on the subject with first hand knowledge, if they are willing to put it in the auction it is more that likely authentic, another way is to send them photos online and their experts will get back to you, what they will say is weather or not they will except it in their auction, with the move, I am still pulling things out of boxes, BTW is there a specialist from one of the high auction houses in your area? Over here Bonham's and Christies offers free evaluations.

In Hong Kong. Last week I asked them (Bobhams) for the email for sending a Chinese item, though. I wanted to ask you some things about Bonhams in this respect.
