The hottest the oven can be is 135 F (57 C). Any hotter and the DMT will boil away into the air. Most ovens can’t go that low, or they are not accurate enough to trust at that temperature.
To speed up evaporation SWIM will put his stuff in a 500 ml crystallization dish (it’s basically a glass Pyrex bowl with a flat bottom) placed on an accurate digital hotplate set to 70 C (the dish never gets hotter than 50 C at that setting on SWIM’s hotplate) with a fan blowing air over the DMT.
One problem with using air is that it causes DMT N-Oxide to form, especially if heat is applied, so it’s not a good idea to completely dry it that way.
A better way to dry it is chemically using anhydrous magnesium sulfate. First dissolve your DMT in a tiny amount of warm naphtha or heptane (no hotter than 55 C, check it with a thermometer). Use just enough to dissolve the DMT. Then add anhydrous magnesium sulfate until the anhydrous magnesium sulfate no longer clumps when you add it. It absorbs the water and forms clumps when there’s water present only. Mix thoroughly and then filter out the anhydrous magnesium sulfate. Then freeze precipitate the DMT. A tiny bit of DMT will be present in the anhydrous magnesium sulfate, which you can recover by pouring a little more naphtha through it.
The beauty of this method is that DMT N-Oxide will not be encouraged to form.
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.
If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
