You can't give up on glass!
But perhaps you might be better off giving up on chipped or damaged bits - I think they only sell well-ish, if they're very scarce and/or very, very old.
A very, very good way to learn is to go to one of the big fairs and handle the pieces and chat to other glassy folk.
There is no substitute for actually holding and feeling it, and looking at it from all different angles.
Not only that, but you'll get to meet a load of us...... or is that what's making you think about quitting?
In general, reccession aside, glass has yet to find it's proper place in the art world, but it's well on its way and it's getting there, slowly, but surely. As a dealer, you can't afford to ignore it, you just need to learn more about it.
