Thread: Little dollar project

Kirinite is an acrylic plastic; in no way is it made of acid treated cellulose. Please check your facts before making broad statements.

What now? Kirinite used as well in the first part of the 20th century?

Kirinite is a recent development of the last ten years, I found references to 2015 as earliest in my search, Google didn't go back any further. I believe they have been around longer.

The replacements for Celluloid were hard rubber, Catalan and Bakelite.
Catalan was the most colorful of them and found mostly in brush handles.

Acrylics were first developed in the early thirties. Lucite being one of the first trade names.

Geezer, I see you’re rather interested in this topic, so to let you know, I mistakenly mixed up Katalin and Kirinite. I apologize for the incredibly irresponsible oversight.

A bit nasty there...If you thought that I was picking upon you; no.
Since you erased the your original post and it only survives in quotes above #12,
Why?
Most of us old timers, when starting out, got our mistakes shoved back by real experts like Pixelfixed and Niel Miller.

If a person acts like an "Expert" and gives misinformation, that has effects down the line when someone passes it on as "TRUE."

My opinion; it took some hard knocks to get me to believe it!

Thanks Steve

Steve, to answer your question, Cell rot (or celluloid rot) is the result of the break down of the plastic that gives off a gas which can cause the blade to rust. You can usually tell that it's cell rot as the blade will rust first only where it is exposed to the scales. There is really nothing that can be done to stop it other than replace the scales. It is also contagious to other razors if stored in the same air tight container, that is why if it suspected than it should be quarantined from other razors.

Thanks Tintin, good to know what to look for and what to do. Replace the scales.
Thanks Steve
