Movies of the first half of the 20th century were filmed on an unstable, highly flammable cellulose nitrate film base, which required careful storage to slow its inevitable process of decomposition over time. [5] Most films made on nitrate stock were not preserved; over the years, their negatives and prints crumbled into powder or dust. [10]
Nitrate film is also chemically unstable and over time can decay into a sticky mass or a powder akin to gunpowder. This process can be very unpredictable; some nitrate film from the 1890s is still in good condition, while some much later nitrate film was scrapped as unsalvageable when it was barely 20 years old. Much depends on the environment ...
