155 emitted particularly near the center of the reel v/-,erc film is tightly wound. In the fourth stage the bubbles spread and a brownish colored foam covers the reel. In the final stage the film breaks down into a brown semi -crystal 1 i ne material. At this stage I am under the impression that it is shock sensitive but that has not been verified. The American Film Institute has nitrate film over 75 years old in better condition than some manufactured in 1950. The decomposition of film may bo attributable to the original quality and purity of the film. That manufactured during the V/orld War II days is lil:ely to be of poorer quality. If nitrate film is spliced into safety film, the decomposing of the nitrate can adversely effect the safety film, Eastman Kodak says in their bulletin "Precautions in Storing Motion Picture Film" for ordinary storage, not valuable archives, and dated Apri 1 1951 : 1) The film should be in metal containers, closed but not sealed, and preferably one roll to a can. 2) The storage space should be cool and dry. The temperature should not exceed 70"F, preferably lower, 3) The relative humidity should be over 25% but not over 60%. 't) Nitrate film should be examined on a rev/ind at least once a year, 5) Film in the early stages of decomposition, as indicated by local image fading or discoloration, should be copied on safety film and then scrapped, 6) Film in an advanced stage of decomposition, as indicated by a strong odor of nitrous fumes, loss of the image, brown discoloration, undue brittleness, crumbling or powdering, emulsion stickiness, etc. is useless and dangerous.
