Someone set me straight if I am wrong, but I thought the decay of the dead
mollusk also could somewhat dull the nacre or the translucency of the shell.
I've noticed this on some species that have had to soak for a while in fresh
water to remove the rest of the tissue. Or is this a reaction to the soaking
in fresh water? Or maybe a reaction to the fact that I was brain dead for two
weeks and forgot about them in the garage til the smell put back the electro-
chemical impulses into my cranium?    Scott
