Yes, I do know. Besides the post from a 3rd party source that I made up in #53 (with source link), and besides TATP being made from nail polish remover, it's generically safe to say that **any** subtance that deteriorates, decays, or evaporates, even water, has a smell at some level.
TATP decays rapidly, by the way.
What evidence do you have that the material you are speaking of was pure? (And, what of the other points in my post?)
