This is an antique blue porcelain plate from ancient Annam, dating back to the 14th to 16th century. It features a tall foot and a rising bowl side with visible hammer marks, giving it a distinctive and charming appearance. The casual craftsmanship of the potters from that era is evident in its design. It also exhibits the characteristic kiln marks found in excavated artifacts. It can be used as a bottle stand for placing a teapot and enjoyed in that way as well.
