need help for crystallization

[vortis]

Hello! I'm new in this community, but I hope you will help me! I have problems with the cristallization of my spice. I have tried solvent evaporation, but I could only get a greasy orange sticky film. so I tried freeze evaporation, but when I removed the cold solvent, and put the crystals on a plate to let them dry, they have dissolved!
so, what can I do? have you got any tips on crystallization??

Thank you for help!

While solvent is cold, and still in freezer use a piece of stainless steel to break up the spice from the bottom, use small amount of extremely cold naphtha/heptane to wet a filter, filter off solids, rinse again with cold naphtha, to get remaining, make sure no naphtha is left in jar, put jar in front of fan to evap away residual solvent, and leave filter containing DMT in very circulated room, wick up excess solvent from the filter with another filter while its cold to prevent any re-dissolving as solvent rises to room temp.
