If I had to marry an inanimate object, I would not choose the Berlin Wall as Eija-Riitta has, but I might be tempted by a bunker, possibly the Boros bunker, whose dark history has been reclaimed by great art.
The BFI is facing what’s already a become a major problem for many who possess collections of early cinema: How do you keep 450,000 cans of film from breaking down, particularly when the film is made of cellulose nitrate, a plastic not known for its longevity?
When cellulose nitrate breaks down, it causes the release of nitric acid, which can accelerate degradation in nearby film. Eventually all the degradation results in a gooey or powdery mess where there was once a fantastic film.
The BFI’s spokesperson Brian Robinson told me that in the new archive, fragile film will be kept at -5 C, which is “down a notch” from the previous temperature (3-4 C) that the film was stored at. According to studies done at the BFI, Robinson says that the cellulose nitrate degradation will “be arrested.”
I can’t imagine that it’s ever possible to completely arrest degradation, but I’m guessing the drop in temperature seriously decreases the rate of chemical breakdown.
Finally, Robinson says the new £12 million facility will be well-ventilated, which I presume will suck away any amount of nitric acid that has managed to percolate off the valuable film.
