Jade: SWIGs product does not hiss or frizzle (I know its a poor explanation but its all that came to mind) when
its heated and melted down so excess hcl can be ruled out.
barkingburro: About your last pull comment, would the meth from the first two pulls be clean and gakk free? SWIG knows that the last pull will pull some trash along with meth so I'm wondering if this might be what happened in your case. SWIG always mixes his dope in one bag so SWIG can't say that the first two pulls was gakk free. But SWIG thinks that this gakk was pulled in all three pulls instead of just the last one.
The first couple of times that the product is melted down it looks clear and clean. Cracks back nice and fast. After repeated heating and cooling, usual about the third time, the color change occurs. The clear liquid, meth, will slowly take on a light blue tint. This will darken to a deeper blue and some will turn brown. At that point SWIG can notice a sweet taste to it. After polishing up what was in the toter SWIG was left some ugly residue to clean up.
What SWIG should have asked originally is if there is any meth left in the bowl when the color change happens? SWIG assumes that there still is some meth left but the majority of whats being consumed would be gakk from the pills.
Seems that there is barely any added effect, if not none, for one to continue to toke on the toter after the color change happens.
