"The Taming of Tungsten" is a chapter in "Men and Volts", a history of General Electric.[1] GE bought up the patent rights of Hanaman, Alexander, and a few others for tungsten filaments. It still took years of metallurgy work at GE to get a production process for making tungsten wire in large quantity. Here's a video of the whole insanely complex process, from ore to wire.[2] That plant was in Euclid, Ohio. Opened in 1913, closed in 2010, now a huge vacant lot. I once lived about two miles from there.

The FBX crypto people ordered a tungsten cube for their lobby, as a status symbol. It was made and delivered, and found in a storage building in the Bahamas. I wonder where it ended up.
