Going gentle gives better results when crystallizing. When you put a room temperature (or even warmer) naphtha solution of dmt freebase in a deep freezer, the temperature drop is so sudden and steep that the dmt rapidly crashes out in the form of very small crystals. Big crystals need time to grow.
I got very nice crystals when I left a jar of dmt loaded naphtha overnight in the refrigerator. Slow evaporation of the solvent can also yield very big crystals.
