This early black and white silent film, possibly created as a teaching aid, shows the growth of a crystal under a microscope. It uses time-lapse imaging techniques to allow the viewer to see a spiral growth slowly appear on the surface of a crystal. This is possible an excerpt from a longer teaching film on the subject of crystal growth. For this film, and several others in our collection, we have tried to contact any known copyright holders and believe it to be an orphan work. If you are the rights holder, would like it to be taken down, or have any more information, please get in touch at richannel@.
