B/W jar (meiping) by: peter
Most collectors never are able to own a Yuan jar or vase during their life, so again, I am unable to say much except that the color is not exactly what it should be, in my view.
The jarlet here shows the actual color of sumali pigments used in the Yuan dynasty. See also this page about blue pigments.
Please draw your own conclusions. Yuan dynasty items mostly need a hands on inspection, due to some peculiarities of the blue color, which are not easily visible in photographs.
