This one of a kind rig was created in just over 12 hours during the legendary Pipe Classic Glassbpwing Competition in Burlington, Vermont hosted by the Bern Gallery. Each artist was given 12 hours to create their entry. This piece was disqualafied from the final judging because it took just over the 12 hours to complete. I bought this directly from Bishop and he told me he would rather his entry look and function up to hos standards rather than rush it for the 12 hour mark. This competition is no longer running, so, it is a rare opportunity to scoop a legendary piece of borosilicate glass history. I am only selling because i got divorced and need funds for other projects i am pursuing.
