This looks like Chinese Imari, late Kangxi, my only drawback is the bottom dose not have any age signs.
That is all right, I think, Stan. In the 'three reigns' period (Kangxi, Yongzheng, Qianlong) the bottom often was flawless, or might have had only a few shallow indents from burst surface bubbles. No brown spots, normally. Generally, the clay/bubble structure was more uniform and consisted mainly of small bubbles. During this period quality was at its best during the whole Qing dynasty. Too many glaze faults or spots contrarily is a cause of concern. That is why I thought the other saucers presented earlier to be unusual.
Thanks Peter, that is good to know, I did not think it was a fake, but that explains it, thanks again.
