I HAVE THE SAME EXPERIENCE (light heat cleans tar) AND I THINK I KNOW WHY:
I think majorigpa was using the wrong term when he said "disperse" because I think Im getting the same or similar stuff and I COMPLETELY know what he's talking about.
I put mine in my nose, "waterline" style, because all I can get out here is tar, or a light tan powder that immediately turns into nasty tar as soon as it can absorb moisture from the air. I dissolve it and filter it the same as one would to IV
past few months I started getting sinus infections probably from putting dirty tar heroin up my nose every day. I started looking for ways to knock as much of the cut out as possible, and possible lower the acidity a bit so it doesnt do as much tissue damage.
I ran across some posts on various boards where some tar users said that by adding TINY amounts of baking soda to their shots before slightly heating, they managed to precipitate out some of the nastier, oiler cuts that looked like shoepolish.
so i started doing this, but the problem is trying to find that "sweet spot" where the ph is such that the dope doesnt' fall out of solution with the cut, too much soda and its ruined.
i started experimenting adding less and less baking soda to see what the smallest amount I could get this "clean up" effect from was.
* note about this particular tar* all of the types of tar I have gotten this to work with are all quite "potent" but nonetheless leave a murkey, muddy, opaque solution even when only a moderate amount (.05 - .35) is dissolved COLD and filtered through cotton
This next part is why I think we shouldnt be so quick to discount MAJORIGPA's insistance that mild heat cleans up his stuff....
at a certain point, the amount of baking soda I added became so small that "bubbles" no longer formed (signaling the beginning of the desired reaction) unless VERY MILD heat was added, allowing the solution to become VERY WARM (NOT HOT).
I quickly realized that my experiment needed a "control" to rule out the bizzarre possibility that warming the solution was causing the majority of the cut to become insoluable.
the results of my control experiment shocked the hell out of me, as prior to this I spent years yelling at all my friends for heating- even warming- their shots.
Cold dissolved, a brown, muddy solution.........slight heat added after the h/cut is totally dissolved, DID NOT AGITATE or stir in any way once heat is added.....quite rapidly, I noticed the microscopic sized particulate matter sticking to itself and forming larger and larger particles, and then globules, then chunks, some sink to the bottom, others float in little "pools" like oil on the surface.....Taking care not to disturb the now seperate cut, a fairly large cotton is dropped into the liquid to absorb most/all of it without re-agitating the cut..........
Result (much to my surprise the first time i did it) is a rig full of super clear light gold liquid the likes of which I have rarely seen on this coast.
In a later test I dissolved half a gram in half a cc of liquid and managed to clean it up using this method into a light gold, urine colored shot- perfectly clear
Practice and experience with this method have taught me that the less heat you can use to achieve this the better- I usually warm the cooker for less than a second at a time and wait for the heat to slowly work its way through the metal to the solution before addinganother half a second of flame, all the while keeping the cooker tilted at a 45 degree angle and slowly rotating it so the cut floating on top collects in one place quicker ( practice and you get a technique down)....
BUT WHY ON EARTH WOULD THIS COUNTERINTUITIVE BULLSHIT WORK?
my theory is that the water, as it comes out of my tap (and most of those in my city), has a PH high enough to lower the acidity of the solution just enough to mimic the effects of adding the tinyest touch of baking soda....
My guess is that were the dope acidic enough, or if neutral/acidic water were used to start with, this phenomenon as experienced by MAJORIGPA and myself seperately would no longer occur until a minute amount of base is added...
THOUGHTS?
