If you saw white crystals.. then what you have left is probobly dmt n-oxide or dmt dissolved in plant oils.

Either way its active.!

What i would suggest if you want crystals is to redisolve it in a bit of shellite (hot shellite), and refreeze (just a little bit of shellite).

Then when the crystals form again, pour off the shellite and keep the glass upside down with a bit of an opening so all the shellite pours out.. leave it like this for a good halfa n hour, then when you scrape it shouldnt go to goo.
