I know you're all probably gonna laugh but this is an idea I have been thinking about for a while. I know a dude locally who makes glass and can hook me up so I am wondering if this is worth a try. The picture sucks but basically it would be all glass except for the metal screen between the unit and the glass bubble. The heating coils would be placed inside glass tubes so it might take a while to heat up and stabilize but I'm not really worried about that. You would just crack the o2 tank open...
All glass vape idea.
