cellulose nitrate

The problem of film decay is not limited to films made on cellulose nitrate.

The film then in use was made from the highly flammable cellulose nitrate base.

It was on a cellulose nitrate base and on the point of disintegration.

Most movies on cellulose nitrate base have been copied onto modern safety films.

In 1870, camphor became the more favored plasticizer for cellulose nitrate.

It is the lowest cost plasticizer for cellulose nitrate.

Nitrocellulose (also: cellulose nitrate, flash paper) catches fire quickly.

In the early days of film, when the stock was made of cellulose nitrate, studios sometimes burned old films for special effects.

A glass flask had become coated with the plastic cellulose nitrate and when dropped shattered but did not break into pieces.

Originally the highly flammable cellulose nitrate was used.

The company manufactured cellulose nitrate (also known as pyroxylin-plastic), the first plastic.

The film print was composed of cellulose nitrate, a highly combustible film stock.

According to the producers the film had a length of around 600 metres, on 35 mm cellulose nitrate film.

Originally, film was a strip of cellulose nitrate coated with black-and-white photographic emulsion.

Unlike cellulose nitrate, B-72 does not need additives like plasticizers to stabilize its durability.

At the works, cellulose nitrate was maintained in 50-inch by 20-inch sheets that had been piled in the surrounding buildings.

Because cellulose nitrate contains oxygen, nitrate fires can be very difficult to extinguish.

Others are the cellulose-based cellulose acetate and celluloid (cellulose nitrate).

The development of cellulose nitrate in 1846 led to the patent of castor oil in 1856 for use as the first plasticizer.

Parkes mixed cellulose nitrate with camphor, producing a hard, flexible, and transparent material.

The chemical instability of cellulose nitrate material, unrecognized at the time of its introduction, has since become a major threat for film collections.

The Nixon Nitration Works rose again on the site, and returned to the business of cellulose nitrate manufacturing.

Cellulose nitrate was the first type of film base used to record motion pictures, but due to its flammability was eventually replaced by safer materials.

The process uses nitric acid to convert cellulose into cellulose nitrate and water:
