I recently purchased this & was curious as if it's possible to remove the metal cap on the glass cylinder without breaking the glass. It really seams likes is sealed on pretty snug from over the years... right about 100 now!! I always thought there is also seal from the factory attached between the cylinder and cap when it was sold new. I just don't want to break the glass, but I would like to clean it somehow... eventually I'd like to put a nice sweaty sphere globe up top and need to deal with getting the right hardware replaced at the top where all the electrical meets as well, so I'd like to attempt to remove the cap if I can.... If anyone has some helpful advice / experience they can share with me, I'd greatly appreciate ya
