UNFINISHED RAINBOWS

"The aluminum industry is traced from Napoleon III's time to the present. Early experiments by Hall to find a cheaper way of processing aluminum and his efforts to find a market are shown. Hall's followers in the field have constantly opened up new fields of use for the metal as in office furniture, electrical wire, train metal sheeting. A story of an industry, but the value of the film has not been impaired." Mary Rees Land. "The most beautiful film. Timely, interesting. Unusual." R. L. Lee, Jr. "A fascinating story of trials and success in the American way." Wilber Emmert. "One of the few films suitable for high school chemistry classes. Shows the role of aluminum and inspires students to consider a career in research work or at a university to appreciate the great labor that has given us our modern products." Collaborator.
