Can anyone here speak authoritatively on the composition of the ferrules on the tops of two piece brushes? I had thought that they were made of hard rubber on the old ones and that more modern plastics made their appearance toward the end of the catalin era. But tonight I was sanding an Ever Ready 75k, a marbled catalin two piece brush with a black top, that I had repaired some cracks on. I sanded the epoxy patches down to match the surface of the ferrule and then sanded the whole thing with a finer grit. There wafted to my surprised nostrils the strong and unmistakable scent of camphor indicating that the plastic was celluloid. Not a subtle scent but a very strong and pungent one.
So I am confused, what the heck were the ferrules made of and was there a difference between the white ones and black ones? What materials were used when? Anyone out there have an idea? Had I known this was celluloid I would have tried a different repair technique.
