This section describes methods for working glass for scientific vacuum devices such as glow tubes, filament lamps and thermionic devices. It is a record of the approaches which I have taken and the problems which I faced. The articles below apply to soda-lime glass and are intended to be read in order, starting at the top.
I am still very much a novice and would welcome tips and constructive criticism from more experienced glass blowers.
