SWIM will never have time to make a nice teq w/pics... So, here's a quick written description. If anyone ever writes up a nice teq please give some credit!
There's two steps that separate out less desirable compounds.
FIRST STEP: Add your crystals and a MINIMAL amount of solvent (bestine or naptha because they are finicky/selective for DMT) to your glassware and use a pan w/hot water to heat it up. You will see the crystals begin to melt into its liquid form.
Now, here's the key to this step: Take a cotton ball/Q-tip and use it to soak up all of the liquified spice. The spice loves cotton and it'll soak up very quickly. Once all the spice is in the cotton, stir and mix the cotton around. You want all of the spice to constantly come into contact w/the cotton. Keep adding a small amount of hot solvent until all the spice is dissolved.
You can tell if the cotton has undissolved spice in it by forcefully wiping it across the glassware. If the cotton has spice in it then a thin film of spice will be transferred to the glass. If it does then keep dissolving.
In the end you will end up with a cotton ball w/no spice left in it. HOWEVER, it will be a nasty brown/yellow/orange color. For whatever reason the impurities tend to be the last thing dissolved out of the cotton. If you keep adding more solvent these darker colored compounds WILL dissolve out... so, you want to stop adding solvent before then. Once all the spice is dissolved, move it over to a second clean glassware piece.
SECOND STEP: This step is basically just a recrystallization technique. There are so many different ways to do it. From boiling hot to freezing, room temperature to freezing, over 10 minutes, over 24 hours, using different solvents. Each different spin/technique/combination does different things and separates out things w/a different twist.
This technique uses the most insulated container possible (styrofoam or many layers of towels). The temperature decline should be as slow as possible using the most selective solvent possible (bestine or naptha.) Dissolve the spice at room temperature. This might take a lot of solvent but I've found it helps a lot. So, dissolve the spice at room temperature using the LEAST amount of solvent possible.
The little trick to this step is this: pure DMT tends to crystallize into pure white/clear crystals(duh) ANYWHERE the initial seed crystal is formed... be it in a high spot, low spot, bottom or side of the container. On the other hand, the less pure DMT/contaminants tends to crystallize into variously colored blobs ONLY on the bottom most areas of the container.
So, knowing this, you will want to use a container that has a convex shaped bottom!!!
Though this is probably total overkill, you can set the fridge to its highest setting and let it equalize... then turn it to the lowest setting and let it equalize... and then move it to your freeze.
Anyways, after it's done crystallizing remove it from the freezer and pour out the solvent(which can be reused). From here you can separate out the pure white crystals w/tweezers and repeat the process on the pools of colored goop. Surprisingly, when you repeat the process on this colored goop you will once again get a bunch of nasty colored contaminants on your cotton ball in step 1 and PURE WHITE crystals w/colored goop in step 2. Repeat, repeat, repeat....
It's even possible to perform these two steps on the pure white crystals. You won't get many contaminants in step 1 but you will get crystals and a CLEARER goop in step 2. The clear goop here is probably just DMT that didn't have enough time to recrystallize during the temperature decline.
And that's all folks!
I don't know if these two techniques are novel because I don't keep up anymore but I hope they are!
