Heraclitus' Recrystallisation Tek


DMT Recrystallization for Beginners:

Recrystallization is an art. There are as many ways to recrystallize as to paint a picture. This is an easy way to recrystallize dmt, but it is by no means the best or only way. This procedure uses naptha because it's commonly available to people working with dmt, but solvents like heptane or hexane work even better.

1. Add 20 to 25ml of naptha per gram of dmt to a glass container. A small flask or beaker is ideal. Then add the dmt.

2. Heat the beaker to 40 or 50C. A pot of recently boiled water is plenty hot. (NO FLAMES OR SPARK SOURCES AROUND NAPTHA)

3. After a minute or two of heat, the dmt should melt and mostly dissapear in to solution. Very often a mass of yellow/orange goo will sit on the bottom and refuse to go in to solution. If at this point the naptha goes yellow, let it cool for a little while and the yellowness should fall out leaving the naptha clear.

4. Carefully pour as much clear naptha off the insoluble junk as you can in to another container. This container must be something that you can recover crystals from later. (optional - while transferring from one container to another, pour the solution through a very small filter of some sort. a bit of cotton ball in a funnel for example)

5. Add another 5ml or so of naptha to the original container, and add heat again. Again pour off as much clear naptha as possible in to the other container.

6. Cool the clear naptha as slowly as possible. Let it at room temperature for a few hours. Crystals should begin to precipitate. (optional - you could add a few seed crystals for better crystal formation) Then stick it in the fridge or freezer for at least a few hours.

7. While the beaker is very cold, pour the naptha off the crystals. Freezer temperature naptha holds very little dmt, but feel free to evaporate it to make sure.

8. (optional - Scrape the crystals in to a coffee filter, and pour 10 or 20ml of very cold water over them.)

And that's it. Repeat as desired.

It's important to remember that not all naptha is created equal, and your naptha may dissolve more or less than 1g per 25ml. If signficant amounts of dmt are left in the original container after you do this process (more than 100mg), use slightly more solvent next time.
