I am glad to here that you are abandoning your "roasting" idea, but i don't think you need to give up altogether if you really want to pursue this. Arsenic trioxide is difficult to obtain, but not impossible. BTW, i was wrong about amounts. I actually bought a 25 gm. bottle some years ago for $25. But there was a hazardous transport fee and the final cost came to just under $50. I just looked on line and found 100 gm. supplies selling for about $60 (plus hazard fee). Considering how much you use in the process that isn't really too expensive. I don't want to make a commercial announcement here, but try googling "arsenic trioxide for sale".
I have spent plenty of time in Vermont and i know that you definitely get a few weather windows of opportunity up there…
