Solid porcelain weight glazed in dark blue. Weights made of porcelain were not uncommon but this is an unusually large one. It has been used over a long period of time so it is not surprising that it is chipped on the rims. This type of weight can usually be dated to the late Yuan (AD1279 – 1368) to early Ming period (AD1368 – 1644). Diameter 7.8 cm. Height 5.5 cm. Weight approximately 400 grams.
