SANCAI GLAZED BOWLS WITH IRON RED BODY

by Andrew

Dear Peter hello to you once again.
The first time I posted 2 vases with what I thought were sancai glazes...these proved modern & probably not even Chinese.

This time I have 2 bowls for your consideration.
Out of interest, they both measure about 321 mm.s in diameter & are about 110 mm.s tall.

I tried to glean the internet for info on Sancai wares & found an interesting site..ucl.academia.edu/ThiloRehren/Papers/1083472/Western_technical_traditions_ofpottery making in Tang Dynasty China: chemical evidence...

to be brief, it explains that in 1999, the Liquanfang Kiln site was discovered by a team from the Shannxi Archaeological Institute in the Western suburbs of Xia'n City.
From this kiln site 29 Sancai shards were found & analysed...15 were composed of ferruginous red clay bodies & 14 with calcearous, yellowish bodies.
The shards proved to be from the Tang Dynasty.

With this said, would you be able to suggest a way I could authenticate my bowls if they prove to be, firstly Sancai,& secondly & more importantly, is there a possibility that they could be Chinese Tang or Islamic Sancai of Tang type?
I looked at examples of Sancai ware on the net from Iran, Nishapur, Samand & even Abbasid splash ware, but can't find anything that matches exactly what I have,but only the explanation of the discovery at the Liquanfang kiln site.
Wikepaedia has 2 photos of Sancai held in the British museum..one is Chinese Tang & the other is an Islamic imitation..but the bodies don't match mine in composition.
After a lot of reading it appears that Sancai during the Tang Dynasty in China was actually made of various clay bodies & not just stoneware or porcelain.
However, there are a lot of differing expert opinions out there, that to me seem, that no test can be 100% conclusive in determining the actual origin of a whole, intact piece in the case of mine, unless it was dug out whole in situ & not just shards.
What do you think?
regards again,
Andrew.

PS: I will put up more than 4 images to give you a better look at the 2 bowls.

MORE IMAGES ON SANCAI BOWL NUMBER ONE

by Andrew

Hi Peter,
this last image is of the base of the first bowl with my posting.
This bowl is actually quite heavier than the other one & has green slip & clear overglaze to most of the undersides of the bowl;
as opposed to the next bowl,(number2) which does not have any slip or glaze underneath, except that the red clay body is showing.
