The freebase is not, not significantly at least. I've seen on the site that dmt HCl is hygroscopic, possibly other salts too.Is DMT Hydroscopic, as in it absorbs moisture from its environment?
Why is freezer percipition white crystals and fan evap goes a light brown colour???..fan evap pic....I think fan evap spice is betterFan evaporation lowers the temperature of the solvent a lot (just touch the container while evaporating), thus condensing water in a humid environment. Freeze precipitation is better due to that among other reasons.
Likely some degree of polymerization or oxidation, but I don't know for sure. Both vials in your picture look light brown to me, and lightly polymerized (small chunks instead of powdery crystals).and fan evap goes a light brown colour
Both are just DMT. But if you prefer one appearance over the other and know how to get it, no one is stopping you from doing it your preferred wayI think fan evap spice is better
It's just more wasteful of solvent.Did you test your solvent for residues? One simple check is to evaporate a small amount on a very clean glass plate and see if anything is left behind.Why is freezer percipition white crystals and fan evap goes a light brown colour???..fan evap pic....I think fan evap spice is better
