A glass bowl in what is known as lidded technology. A layer of blue glass was applied to the clear glass bowl, which was then sanded off so that only the lotus pattern and trim remained. This style was popular north of the Black Sea, and the bowl may have been made by a skilled glassmaker in today's Romania, Ukraine, or southern Russia and then delivered to Uppokra. It may have served as an allied gift between rulers, to be used later as a liturgical vessel. The chalice was found buried by the fireplace in the house of worship, along with a magnificent goblet.
