This quirky napkin ring always resided in my grandparents’ china cabinet — right by the Silver one (earlier post). I am not sure what material it is. It almost appears to bakelite.
Some people who are well-versed in Bakelite identification recommend the hot water test as the standard when it comes to accurately identifying this form of plastic. In this method, the piece of plastic is placed under very hot running tap water. The heat from the water releases the formaldehyde-like scent of Bakelite.
I really do not want to do this. Maybe, I will leave it to my heirs to finalize this one.
