I strongly disagree with the statement that Kodak marked its NITRATE film in Red print Between the Perfs. In over 35 years of working with the material I have Always seen the word Nitrate printed in Black ink on the Base side of the film Between the line of perforations and the edge of the film. Another way Kodak identified Nitrate were the Splicing tics (small dashes every 4 perfs) if the tics are paralell with the film it is safety film if the tics are at a right angle to the legnth of the film it is Nitrate. Another thing to keep in mind is that you will often see the markings in clear on a black background, if that is the case especially on positive films it is the effect of printing thru the black ink markings of the negative.

[edit] No 16mm or colour negative nitrate motion picture film was manufactured
The sentence 'Color negative film was never manufactured with a nitrate base, nor were 8 mm or 16 mm motion picture film stocks.' is certainly incorrect on one count, and probably on two. The Soviets and Chinese manufactured 16mm nitrate, at least to a limited extent. I have personally handled a 16mm nitrate print of 'The Green River Flows East' (China, 1949). For anecdotal evidence of Russian 16mm nitrate, see Roger Smither & Catherine Surowiec (eds.), This Film is Dangerous: A Celebration of Nitrate Film (Brussels, 2004), p. 197 (footnote). There were a number of single-strip lenticular and chromogenic (dye coupler) colour systems which predated the commercial introduction of cellulose triacetate in 1950-52, e.g. Agfacolor and Dufaycolor. While I have no proof that the negative stock was manufactured on nitrate base, I see no reason why it would have been on one of the pre-triacetate safety bases that existed, but were only used on a very limited scale for motion picture film, pre-1950 (e.g. diacetate, propionate). Two- and three-strip Technicolor negatives, though not strictly 'colour' in themselves (as the emulsion on each was monochrome), were certainly nitrate.
[edit] C6H8(NO2)2O5 ?
Aren't there only 7 hydrogens in nitrocellulose? Cellulose has 10, and 3 hydroxyl groups are nitrated, yes? I'm not quite positive, but I'll make the change in a few days if nobody objects. 72.40.101.236 19:34, 29 June 2006 (UTC)
- Wait, shouldn't there also be 3 nitrate groups instead of 2? 72.40.101.236 19:38, 29 June 2006 (UTC)
[edit] Rocket Fuel
Was nitrocellulose not also used as rocket fuel (rocket propellant)? See the entry on Wikipedia for katyusa rockets.

[edit] Another use for flash paper
I understand flash paper used(?) to be used by bookies because it could be instantly destroyed in case of a raid -- particularly easy in the days when everyone smoked. Or maybe that was just on TV... --Wfaxon 22:17, 15 October 2006 (UTC)
[edit] How to make
Hi there how do you make gun cotton or where can i get flash paper and is it possable to make flash paper??
the reason for this is for a film me and some friends want to make however we cant find flash paper (not even in magicians stores)
Also how does one go around making that Fireball from flash paper? you know the one that looks like its a supernatural power comming from the persons hand? in anyways thanks in advance !!! One more thing whats the safest distance to be at when making a fireball from your hand? (in the term of the other object)
