Well, I said "live and learn", but I did it again  last time I was extracting  the DMT juice from acacia.  But htis time it was the third extraction hat burned,  so I still  had the juice from the first two, thus still quite potent.  But I am resolved now not to get involved in anything else for more than 5-10 munutes while the brew is close to boiling down!!    Learn and live!
