Porcelain 10” I had this appraised before but can’t find it on my collection
You have a 19th century Chinese export vase with a well known and appreciated double gourd form. The marking on the bottom is associated with Kangxi period ( ca. 1700 ) but yours is made in the 19th century ( Kangxi revival ). Blue ground color is decorated with plum blossom and the object in the centre is a incense burner. Nice vase.
