Oh i see...you should have just replied in that thread; it would have bumped it to the top and helped with the clutter
Yeah thioacetamide itself doesn't stink, but it releases H2
S which smells like rotten eggs (and is extremely toxic so don't breathe in much and make sure you do this in a place with good ventilation).
It is hard to tell from your setup if the H2
S didn't react with your coins already which would explain why you didn't smell anything after a day or so. To test for the quality of your thioacetamide I suggest following Borek's adivice by taking a tiny amount of thioacetamide and dissolve it in water (no fancy appratus), and heat it up on it's own out in the open air to test for the production of H2
S fumes. Once you smell that, immediately cut the heat because you know it is working. Then once you know it is working, proceed to the coin setup afterwards.
