"Posting Glass Pipes on GlassArtists.org ---------------------------------------- Because non-functional pipe pieces have started to crop up I have further clarified the "no pipes" rule for GlassArtists.org. Functional pipe pieces may not be posted, and non-functional pipe art is allowed. A non-functional pipe is one that is either impossible or would be very difficult to actually use as a smoking device, one that is a part of a larger art piece, or one that is so large, awkward, or otherwise impractical that it's very unlikely that it's owner would ever consider using it as a smoking device. I think to most of you who make pipes this distinction should be fairly clear but if you have a true borderline case let me know and I will consider it. Please note that I will not make an exception just because a pipe is especially elaborate, beautiful, expensive or artistic, as long as it looks like it COULD be used as a functional piece." -from site admin
