About a decade ago I made some incandescent light bulbs out of surplus labware
for a client. I made my prototypes with 250 ml e flasks and the final bulbs
with 2,000 ml flasks. I had great luck working with the pyrex glass without a
cooling oven. Two of the three finals burned for over 200

Reading the thread on fake gigantic nixies got me thinking about the
possibilities or REAL gigantic neon applications. Is there a practical limit on
how large a neon indicator could be? Using traditional methods, would it be
possible to make a neon glow lamp from say a five gallon carboy?

But, unlike a picture tube, you could put internal support structures
within the tube which would make it unnecessary to have really thick
glass in specific areas.
Then it becomes a matter of how you would glass-cast it and insert the
cathodes. A 7-segment giant nixie would be relatively easy
Common nixie tube envelopes have advantage of egg-like shape, the
stress is uniformly distributed in the glass.. Picture tubes have one
side flat what makes the shape more prone to implosion.. Also proper
annealing will be important.
Good remark anyway!
