I love to watch Antiques Roadshow - on tonight - but as long as I've watched it, never saw anybody bring a BOTTLE! Anybody ever see one? All sorts of glass, but no bottles. And not on any of the HGTV collector, flea market or appraisal shows either.
The owner also had an embossed target-ball (embossed with the glassworks name) which the "expert" identified as something "you filled with water and threw at a fire." I was appalled.
My point is that this may be the reason we don't see more bottles -- lack of expertise on the Roadshow staff.
