Biri

Biri Glassworks (Norway) was operating in the period 1761-1880 and produced window glass, bottles and glass floats. There is no actual proof that the marking 'B.V' located on the float's seal button stands for Biri Glassworks but we believe it could be the production marking of this particular Glassworks.


'B.V' marked float sized 5" in diameter. The color is moderate green. With a netting. From our  collection.
