Hi, thats the same with me, I also rather works with glass than write on web ;-) I am making exactly what You wrote - simple glow lamps, filled by argon. I seal them and run them as long as possible. I make one with pressure just enough for the glow to cover all the cathode evenly, stainless steel electrodes spot welded to dumet. After 14 days of glowing (@250V) the dumet started to sputter (or it was sputtering all the time, after that time it was visible) and probably caught some impurities and lowered the pressure (worked as a getter), so the sputtering became faster. And yesterday some problem occured in my power supply and the voltage went to 400V, so today all the bulb is covered with sputtered material ;-)
I am still waiting for stainless steel foil from USA, when it arrives, I will start to etch nice (I hope so) electrodes.. Also going to prepare some alumina solution to cover the dumet to prevent from sputtering. http://dalibor.farny.cz/sealed-argon-tube/ Dalibor 2012/6/26 jb-electronics <webmas...@jb-electronics.de> > Hi, > > Do You have any info about your progress on your site? > > > I am currently training my glasswork "skills", which is really a lot of > work, so this eats up all my spare time at the moment.
