i drilled a stem hole and a carb hole in a wine bottle (dremels are awesome) and am using a copper pipe stem with a brass joint compression nut as a bowl.

:jointsmile:is the copper far enough removed from the flame to be safe?
:rasta:Will the smoke going through the pipe be so hot as to be unsafe?
Also, what kind of metal are the screens in bowls made of?

Thanks for any replies

What are the issues when it comes between Glass and Acrylic? 2.) When building your own, what are some common materials that're safe and unsafe to use? Where does Copper stand? THanks anyone who can help. Rating: 5
