These are what I assume to be 8" tall bottles but they could almost be vases. They are really roughly made with hundreds of large and small bubbles, inclusions and horizontal lines from the shaping process. The pontils are rough and I think show signs of being cut off using glass shears which was common in the Victorian era. Because of this I'm guessing they are mid 19th. century but they could be earlier or later. They do glow under UV but not very strongly which may be due to Manganese in the glass or possibly they do contain some Uranium but not having a Geiger counter I can't test this. They are more green than the photos show.
The reaction to uv is that of manganese, not uranium.
Thanks DuDa, I think you're right but they are still interesting bottles.
