Re: Fascinating Documentary about Quartz crystal manufacturing
I'd suggest that the filming was highly staged and contrived. It was probably intended to be shown to young military radio operators during training, who had to be kept interested. For that purpose it would have been very good
The young woman who was shown doing the etching had very long, highly manicured and painted fingernails. In real life, I bet she worked in the office; probably the boss's secretary. Etching quartz almost always involves hazardous fluoride solutions; they probably didn't want to show their commercial rivals how they carried out such processes, nor other aspects such the ageing methods mentioned above.
I'd say that using it for modern HSE training would probably be slightly unscrupulous when you don't how they really did things.
