Tungsten Filament

Tungsten is rather hard and brittle, so the challenge here was to make a filament that would hug a tapered ceramic crucible to be used inside of a UHV chamber.

The purpose of the filament was to heat metal samples past melting to vaporizing. This way the vapor could be analyzed with a spectrometer to learn which materials were present in the sample.

The coils are progressively smaller towards the left to fit the taper. I had to make six or eight while I was at it.
