Colored Glaze Ring

This is coloured glaze ornament of the Yuan Dynasty, which was collected from the first ancient coloured glaze workshop site unearthed in China. It has a diameter of 2.1 cm and a weight of 2 g. It shows that people in Boshan were able to use colored glaze to make various exquisite trinkets that imitated jade and agate, and that the production of colored glaze in Boshan at that time had already had a considerable scale, which was beyond the reach of other places.
