Hello all - I am a collector of bottles mostly-(Owl Drug, Poisons, early shot glasses, etc) I like all old glass and can't pass up a nice piece of glass at the thrifts- I found 5 of these cobalt 6" diameter net floats in Eugene OR today. I know very little about this area of glass. I can tell that these are very thick, have some bubbles and imperfections in the glass. They have no makers' marks. They all have water marks in the same place and look to have come from the sam net. Its so rare to find 1 real antique glass item in a thrift much less 5 of them at the same time which made me think maybe they are repos but they just don't feel like that. If anyone has an opinion on them I'd much appreciate it and would love to gain more knowledge on these items.
