Mr. Ma Weidu accidentally got the tin is indeed no matter from the glaze or shape, are most close to the current collection of Chenghua bucket color tin. Very pure red, yellow, green, and blue color. It is a pity that the character "heaven" was written a little thin, but for more than 20 years in Chenghua Dynasty, the person who wrote the character may not be the same, and a slight difference is normal. My Chenghua bucket color small dish glaze color is very close to Chenghua this dynasty, the fetal quality is also very good. I think even if it is not Chenghua, it is probably copied by the imperial kilns after the Ming Dynasty. And most of all, the charm, if you put it together with the chicken cup and the jelly pot, it's like a natural thing.
