You could fill it with co2 .put an animal bladder on the mouth of a clay bottle where something is fermenting like wine or beer. The yeast will produce a fair ammount of c02 and fill the bladder. Use the bladder to fill the bulb. It wont last long but it will be longer than just air

atyaz@reddthat.com 1 year agoLightbulbs are pretty easy to make if you:
- Can find a jeweler or blacksmith like you said
- Can generate a ton of electricity somehow
- Are okay with the lightbulb lasting no more than 1 second

If you could find a way to fill the lightbulb with a noble gas as you insert your filament, i think decent life is reasonable.

I don’t even know where to get that here never mind in times of yore

One way is the fractional evaporation of liquid air until all that’s left are the noble gases. Or chemical extraction.

You can also use a sacrificial gas that burns off before the filament. Saw it in a youtube video youtu.be/ThBkzEfjVl0?si=gJW8JyD8KM1Y5Ye8
