That's an amazing video. I was surprised by how many steps it took to make a crystal. Also noteworthy is how many different tests and checks they did on each crystal.
The technology is an interesting mixture of sophisticated and primitive. On the one hand, they had X-ray machines to determine the crystal alignment, and lots of specialized mechanical and electronic machinery. On the other hand, people were spooning abrasive out of a pot with a dinner spoon. Everything was very manual and labor-intensive, with no automation. An interesting mix of highly-skilled precision labor and low-skill tasks.
- tedd4u 6y agoWould be very interesting to see a current-day behind the scenes video of 2021 manufacturing process and compare to 1943. I wonder how many humans touch current day crystals. In the video it’s at least at least a dozen.
- kens 6y agoI found a video of modern quartz crystal manufacturing. It doesn't have explanation, so it's basically fancy high-tech machines doing mysterious things: https://www.youtube.com/watch?v=Own-5Qz_vSs https://www.youtube.com/watch?v=Own-5Qz_vSs It's interesting to compare the scale. In 1943 they were packing a box with a few dozen crystals, while the modern manufacturer fits probably 18,000 tiny surface-mount crystals in a box.
