About the author : Dalibor

I started training glassblowing, the glass tube mounted in my metal lathe. It is not so easy as I had thought! Right flame, right temperature, right pressure on the glass.. Many aspects of the working with glass to learn.. By this simple project, I want to practise:

  • Making the leak-tight stem
  • Sealing the previously prepared stem into glass tube
  • Blowing of the round end on the glass tube
  • Making a tee-joint for evacuation pipe
  • Leak detection
  • Pumping and tipping of the tube
The latter two steps were still not made, but I am going to put it right soon!

There is a moisture in the tube, so it is a bit blurry.

      I am sorry, I missed your comment.. It was prepared for filling with gas, however I realised that one electrode was cut off during making the pinch. So I actually have only one working electrode in the tube and I am not able to make it glow ;-)
