I'm curious, how does Alumilite hold up in the long term? I mean decades or even centuries.
Alumilite is a very popular material for custom fountain pens. Looking at something like "Mineral Sea Lava Explosion Alumilite" or "Arctic Koi Alumilite" it's pretty obvious why that is.
However, there are a lot of vintage fountain pens that exhibit shrinking, warping, brittleness, and/or discoloration, and I wonder what will all those Alumilite fountain pens be like in 50 or 100 years.
Does the kind of Alumilite used matter? What about dyes and fillers? (I'm particularly interested in tinted transparent Alumilites.) Precision of the mixing ratio?

When measured, mixed, and cured properly and fully ... Alumilite resins become an inert piece of urethane plastic. Unless exposed to deteriorating elements for prolonged periods of time, I would not expect any degradation of the materials. Alumilite has been in business since 1988 and we still have some opaque cast pieces from around that time frame that show no signs of aging other than some slight light discoloration (and dust). As far as clear pieces go ... have pieces from 10-15 years ago that once again may show some slight discoloration (only noticed in the pieces that had no dye, tint, or filler in them ... were cast water clear) but not other signs of degradation. So I can not tell you I have pieces that are 50-100 years old but am not aware, nor have I ever seen any degradation of our materials over time that would lead me to believe the pieces would some how deteriorate over time as they are not simply a cured piece of plastic.
