I’ve recently developed an interest in scientific glassblowing and have been in the process of cobbling together the necessary equipment for about a month now. Besides an oxy-fuel torch, serious glass-blowing requires a torch holder to keep the torch flame stationary relative to the bench while both hands are used to manipulate the work. Commercial torch-holders sell for $70 and up, but it seemed like such a simple device that I decided to try junking one together. And this is the result. It’s based around a marble trophy base I nicked from my High School band hall when I was, like 17, and have been carrying around ever since. That’s a pack rat for you.
