    I forgot about meteorite dust, found in some Dupont pens.

    Thank you. I will add Meteorite dust to the list of powdered materials encased in resin.

    We are getting really esoteric now.

    I also remember that I once had a ball pen with shredded banknotes encased in clear plastic. But that was a ball pen, so does not count.

    I see that Cult Pens currently list Platinum #3776 made from celluloid. I had thought it not used any more because of the spontaneous combustion problem with cine films.
    Modern celluloid is cellulose acetate, which is more stable than vintage cellulose nitrate (the potentially explosive/flammable film stock kind). Wiser heads than mine can explain why, and which kind Platinum uses. http://www.fountainpennetwork.com/fo...-of-celluloid/
    Cellulose acetate is not celluloid; “celluloid” refers specifically (and only) to cellulose nitrate.

    Platinum uses celluloid, not celluloid acetate.

    Thank you for pointing me to Tactile Turn. I feel a pen purchase coming on again.

    The only problem is that I see that they make ballpens from Zirconium, which I have never heard of before. Now to seek a zirconium fountain pen.

    Does that mean that a celluloid Platinum could eventually self ignite?

    Put quotes around 'modern celluloid' if you prefer.
    Here's David Nishimura: "... much of the so-called celluloid on the market today is actually cellulose acetate ..."

    Thank you. I have started a conversation with M. Faivet. There may be an indestructible pen on its way to me soon.

    Helped empty my wallet!!!!

    Matthieu is going to use a watch winder from a broken old watch belonging to a dear departed friend as a roll stop. Brilliant idea of his.

    A watch winder is the usual Ubik's roll stop.

    Well, empty wallets are lighter. LOL

    That craftsman and artist can make any pens out of any material it seems
    I love that he replaced the fiddly C-ring with a pin for the lever.

    That's a really shiny pen. Lots of polishing to do there. Amazing.
