Lab grown quartz crystals: How its done.

Following up on yesterdays post regarding the manufacture of radio crystals from natural quartz crystals, I was able to find this video from the AT&T archives showing the relatively new, at the time, method of growing quartz crystals in the laboratory.

The video, produced in 1962, shows first the frustrating failures and ultimately the ability of Bell Labs staff to reliably produce the invaluable quartz crystals.

Very little of the technology we value today would have been possible without the hard work and perseverance of these early pioneers.
