In the early to mid 1920s, a pioneering film maker Claude Friese-Greene and his assistant, drove a car from Land's End to John O'Groats. Using a specially developed process of early colour photography christened 'biocolour', their journey was immortalised in a documentary The Open Road, the purpose of which was to show off the new process. Due to film limitations only a narrow spectrum of blues, greens and reds could be captured by Friese-Greene's method, nevertheless the result was an impressive colourful snapshot of Britain in the 1920s.
To show off his colour photography to its best advantage, Friese-Greene mostly filmed rural scenes, the bucolic imagery of which suited his additive process, but there were occasional forays into industrial areas and one of these was in the Potteries and internal evidence suggests that the visit took place in 1926. After a brief panoramic view of the district from some high vantage point, Friese-Greene then visited the Wedgwood factory at Etruria. Here he found to his delight that he was able to film indoors quite easily due to the large expanse of windows in the workshops. He filmed a thrower at work and paintresses putting finishing touches to the wares. This was followed by a perhaps overlong display of Wedgwood wares from vibrant lustres to the more subdued colours of the famous Portland vase.
Suffice to say, though ingenious, Friese-Greene's technique never took off, losing out to the more versatile Technicolor. As a result, his film went into storage and remained unseen for 80 years until it was restored and aired in 2006 in a BBC documentary entitled The Lost World of Friese-Greene.
