Where do you get glass bottles? Sounds cool. I would purchase glass bottles too, if it weren't for the fact that they cause gas so bad. Some babies are fine, but most babies need bottles with some kind of air-elimination system in it. I went through a couple different kinds with Eli, the playtex ones with the bags that eliminate air because the bag goes down with the formula and then the playtex vent-airs which have a vent at the bottom that lets in air as the formula gets sucked out. Everything else (solid bottles, any of the regular stuff) just filled him with bubbles and gas. Sucked.
I don't know what the glass ones look like though. That would be nifty.
