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

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

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

Early films were coated onto a nitrate base material which was prone to combustion if stored in uncontrolled temperatures.

Usually the sticks of nitrogelatine in a wood Pulp and sodium nitrate base was wrapped in that distinct tive brown greased paper.

In 1965 a systematic programme began of conversion of film prints on the highly unstable cellulose nitrate base, which remained in commercial use into the 1950s, to security film.

Kodak discontinued the manufacture of nitrate base in 1951, and the industry transitioned entirely to safety film in 1951 in the United States and by 1955 internationally.

Research by members of his magazine's staff led them to believe that they were dealing with a slow orthochromatic film on a nitrate base that had lost a great deal of sensitivity over the years.

When a film on nitrate base is said to have been "preserved", this almost always means simply that it has been copied onto safety film or, more recently, digitized; both methods result in some loss of quality.

Slow projection of a cellulose nitrate base film carried a risk of fire, as each frame was exposed for a longer time to the intense heat of the projection lamp; but there were other reasons to project a film at a greater pace.

As it was intended for amateur use, 16 mm film was one of the first formats to use acetate safety film as a film base, and Kodak never manufactured nitrate film for the format due to the high flammability of the nitrate base.

In the Bangalore blasts an explosive with an ammonium nitrate base was used, while in the Gokul Chat and Lumbini Park explosions in Hyderabad a similar ammonium nitrate base was used.

Film stocks in smaller gauges intended for non-theatrical or amateur use, 8 mm, 16 mm, and others, were not manufactured with a nitrate base on any significant scale in the west, though rumours persist of 16mm nitrate having been produced in the former Soviet Union and/or China.
