[SPA] película de nitrato | La base de película de nitrato fue la primera base transparente flexible plastificada disponible comercialmente, gracias a los avances de celuloide de John Carbutt, Aníbal Goodwin y Eastman Kodak en los años 1880. Eastman fue el primero en fabricarlo para la venta al público, en 1889. Desafortunadamente, el nitrato también tenía la desventaja de que era sumamente inflamable (puesto que era básicamente el mismo químico que el nitrato de celulosa) y se descomponía después de varias décadas a un gas menos inflamable (dejando la película pegajosa y viscosa), y finalmente se transformaba en polvo. | FUENTE : Base de película. in: Wikipedia.

[ENG] nitrate film | Film base | Nitrate | Many nitrate films have been transferred in recent decades to safety stock, and original nitrate prints are generally stored separately to prevent a nitrate fire from destroying other non-nitrate films; the gas they release also affects the emulsion of safety film. Usually nitrate collections are even split up into several different fireproof rooms to minimize damage to an entire collection should a fire occur in one part. It is normal for a theater today to pass rigorous safety standards and precautions before being certified to run nitrate films; this includes a fireproof projection booth, fire chambers surrounding the feed and take-up reels, and several fire extinguishers built into the projector and aimed at the projector´s film gate with a trigger released if the film ignites. Nitrate film is classified as "dangerous goods", which requires licenses for storage and transportation. | Nitrate film stock was used in every major film production before about 1951. Many silent films only survived because they were printed to 16 mm film, which did not use a nitrate base. A report published by the United States Library of Congress in September 2013 states that 70 percent of all American silent feature films are lost. | SOURCE : Film base. in: Wikipedia.

[ENG] cellulose nitrate and
[ENG] nitrate | Nitrate : In the literature of photography "nitrate" is used as a synonym for the chemical nitrocellulose. It is also referred to as "cellulose nitrate". Nitrocellulose is guncotton, the first replacement propellant for gun powder in firearms. Film stock with a nitrate base was the first transparent flexible plasticized base commercially available, thanks to celluloid developments by John Carbutt, Hannibal Goodwin, and Eastman Kodak in the 1880s. Eastman was the first to manufacture the film stock for public sale, in 1889. Unfortunately, nitrate also had the serious drawback of being extremely flammable, the characteristic that made it a suitable substitute for gunpowder. It gradually decomposes producing a flammable gas, becomes sticky and, at a late stage of decomposition, the film oozes a goo-like fluid, ultimately leading the substance to become dust. As this happened, the possibility of auto-ignition increased further. | SOURCE: Film base | Nitrate . in: Wikipedia. Available at : https://en.wikipedia.org/wiki/Film_base Accessed : 19 nov. 2022
