Lots of things in play here - how pure was the naphtha pull (was there any brownish coloration?), how saturated was the solution (how much actual DMT was in naphtha), what kind of dish are you using, what temperature (you suppose to put your freezer on maximum for best crystallization, make sure to remove food as well).
That white ice in the bottom is your freebase DMT and I'm guessing the reason why you are not getting a bigger crystals is that the temp is too low and the solution is not saturated enough. You can recrystallize it again to see if you can grow those crystals but its a careful process that takes time.
Just redissolve your "white ice" (DMT freebase mostly free of the solvent) with the lowest amount of fresh naphtha again, pour it in the large glass dish (covered with foil with holes in it to let the solvent evaporate) and let it sit for a day,
then stick it in the fridge (not freezer) for 6 hours or so,
then take it out for an hour or two and
then move it to the freezer set to the coldest temp for another day or until you see crystals forming.
You can also put it on top of the working dryer (for vibration purposes) when take it out from the fridge and before freezing it for better seed crystals formation.
Have fun!
