Yes - This clip is from the 1962 film, Heat and Its Control, from the U. S. Bureau of Mines, in cooperation with the Johns Manville Corporation. It is in the public domain and you can you it. The film is about the importance of controlling heat, chronicles man's use of heat-energy sources and explains radiation, convection, and conduction heat transfer. The film shows heat insulation production from magnesia, rock-wool, asbestos and celite (diatomaceous earth). The entire film is available at the US National Archives in Maryland.
Crazy to see everyone working with no protective gear, poor guys must be breathing in so much dust. (nose wipe at 2:46) Thanks for the upload!
Thank you for the upload. It was informative.
My right ear is so lonely 😭🥺
Hello, Mark. Can I get your permission to use this video for the National Museum of Natural History in the Philippines?
