Hand Blown Bongs & Recyclers by Culprit Glass
A local artist that we have worked with with many year, Culprit Glass does amazing work. He uses Borosilicate glass in all his work which makes the pieces stronger and more resistant to heat. 
Take a look at these beautiful, one of a kind pieces and I dare you not to buy one.
All these pieces are made for a 10mm male banger
 
What is Borocilicate? 
Borosilicate Glass is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion. This means it will not crack under extreme temperature changes like regular glass. Its durability has made it the glass of choice for high-end restaurants, laboratories and wineries. What most people don't realize is that not all glass is created equally.
