[QUOTE="Any Jewelry, post: 1134880, member: 2844"][USER=29]@Ownedbybear[/USER] , it didn't stink after being in a bag overnight.;) In the meantime I found a highly sophisticated state of the art testing method on a Dutch site.:pompous: They said to tap two pieces of bakelite together, two pieces of celluloid, and celluloid and bakelite, and listen to the difference in sound. Celluloid has a higher clicking sound, bakelite a lower pitch 'clock'. So I tested bakelite pieces and celluloid pieces, and these beads have the higher pitch click.
