Fire and sand
Also known as: O-I: fire and sand
Title from title frame.
A basic guide to the manufacture of bottles, with additional information about glass packaging, glass properties and glass furnaces, as well as a brief promotion of recycling. Includes brief footage of an early Michael Owens' bottle machine. In general it offers a very good explanation of how bottles are made.
Possibly an updated version of a 1983 film of the same title, produced for Owen-Illinois by Beardsley & Associates, which was 13 minutes long. CMGL does not have the 1983 film.
Although the beginning has a statement about the film containing proprietary information, the scenes of the manufacturing equipment are the only possible proprietary information.
