Beautiful new old stock, [vintage item never used] porcelain lab bowls. These large, shallow vessels have a single small spout and an imprint on the side that reads Haldenwanger, Berlin. Germany, one of the premier makers of porcelain lab ware. The interior is fully glazed a milky white, the exterior is glazed halfway down the bowl with the remainder being white unglazed porcelain. Because they've never been used they're food safe should you want to use them as a serving bowl.
The bowls measure 10" / 25 cm across 3" / 7.62 cm high.
