Large Thai Sawankhalok round form covered stoneware box in the shape of a mangosteen fruit decorated in iron-black/brown glaze on a buff-colored ground with a zig-zag pattern on the lid and stylized scrolling vines on the bottom. Stem finial. 14th to 16th century. 4 3/4” diameter x 4” high. Very good overall condition. There is a tiny pinhead-sized flea bite on the bottom section at the edge of the rim (see image). The lid matches well and appears to be original. From an old Scottsdale, Arizona collection.
