For The Italian Celluloid Nitrate Geeks Out There (Like Me)....

Recommended Posts

Found a couple of interesting articles relative to the preservation of celluloid nitrate film that may be of value to pen collectors:
In summary, their recommendations are consistent with what many FPN regulars already know, ie. to store celluloid nitrate in cool, dry environments so as to slow the decay (ie off-gassing of nitrates) - 40 degrees Fahrenheit (2 degrees Celsius) and 20%-30 % humidity being optimal (at least as regards vintage celluloid nitrate film).
The researcher in the second article concludes that "happily, primary decomposition catalyzed by temperature and moisture is also very slow in ambient conditions, and slower still—indeed, virtually negligible—at the temperature and humidity levels recommended for long-term storage of nitrate film (40°F / 2°C and 20–30% RH, respectively)". Of course, it bears repeating that one should locate celluloid pens apart from each other to reduce the cumulative effects of their off-gassing.
Loved the example they quoted from Kodak that their celluloid nitrate print material made in 1932 had a predicted lifespan of fifty years, while a print on celluloid nitrate stock manufactured that same year by Dupont had a predicted lifespan of 600 years (!)

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
