As a note, unless it is deteriating, or chopped up into fine particles
nitrocellulose is not as bad as it sounds in this thread. You would
probably have a hard time igniting that billiard ball mentioned for
instance. But once burning it would be almost impossible to put out.

A web search turns up a mixed bag about the explosive properties of
Nitrocellulose billiard balls, some seem to think that the paints used
to color them might have acted as a primer...
Anyone interested in experimenting?

Thanks for the correction, Bob. I actually did a bit of googling,
instead of just recalling from memory, and found that the Cellulose
acetate has an ignition temp of 800F and the Estar base 900F. I'm
assuming the cellulose nitrate ignited at much lower temperatures.

LOL! Nitrocellulose, AKA, gun cotten is classified as an explosive.
BTW they use it for paint too. Gives a much nicer look than Acrilics
paint does. It is still the preferred finish for guitar and other
instrument sound boards as it give a much mellower sound.

The dope used to stiffen the fabric on early airplanes was cellulose
nitrate and highly flammable. Many a WWI aviator chose to jump to his
death sans parachute rather than burn to death in a flaming aircraft.

Anyone have any ideas about what kind of Kodak film it might be?
It is Kodacolour-X.

Excellent. Thank you Bill.
