These are two small ‘ritual wine cups’ from the Tang dynasty, 618-906 AD.
They are made from a white, high fired clay, which feels ‘chalky’ when touched. They have streaks of green and brown glaze over a white-yellowish slip.
The footrims are flat as seen on a lot of tang wares. These cups are hard to date, because there are a lot of good fakes around. Key is handling as much of these Tang wares as possible.
I still think it is hard to single out the fakes, so I do make mistakes. But that is all part of the learning curve. Luckey I had the opportunity to have these authenticated by a world class dealer. He just needed seconds to make his judgement, experience, experience….
Some more cups in my collection;
Collection-nr 21-2014. Possible a sancai ware from the yaozhou ovens.
