Original description
Manufacture of optical glass
Optical glass is ground and polished to an incredible accuracy. This film shows how the sand is purified and bilted and how the pieces of glass are smoothed and polished in lenses for optical metrometers, survey instruments, microscopes, telescopes and camera lenses.

Did you know?
- The highland sand mine featured is the Lochaline silica sand mine, which opened in 1940. Although closed down in 2008 the mine was re-opened in April 2012 and to this day provides high quality sand for glass making in the UK.
- Alongside Queen Cotton and Power Lines, this is the third film in the British Council Film Collection that describes the workings of the technical machinery in industrial production as having a "symphony of sound and colour".
- Footage from an aerial camera, such as the one seen at 03:20, can be seen in British News No.2.
