normal evaporation gave the following white DMT crystals once dried:



but after freezing the naptha for 24 hours at a very low temperature I threw the lot through a filter and got this yellow powdery slude. The naptha is a yellow color:



it has tiny crystalline structures but nothing like the shards the standard precipitation gave. It's drying out now to see what appears.

Any suggestions on what has happened?

Thanks.

looks like water contamination...

Did you seal the freeze precip container 100%?

If not, condensation will form on the inside of your precip container.
As the room temp (or warmer) container cools to the temp of the freezer water will be pulled out of the cold freezer air & condense on the inside. Once condensed it freezes to ice & usually looks very similar to dmt crystals.

But once taken out of the freezer, they melt & although freebase DMT is not soluble it water, it does make it take a whole lot longer to dry & will not allow normal crystal growth.


Recheck your freeze precip method!

Seems to me there's nothing wrong, its just remaining solvent warming up making the whole thing kinda melted. Just let the whole thing dry thoroughly now and it will be just fine, more powdery instead of sharp crystal formations but good just the same.

Next time, do the trick to retrieve crystals from freeze precip as said in the FAQ. And if you want to grow crystals with freeze precip, just keep alternating between room temp/fridge, and between fridge/freezer every couple of hours for a few days (though that wont really change anything, in the end it will all have same effects )

thanks guys. The container was absolutely airtight, in cold for about 24 hours. There was obvious "sediment" after about 5 hours. The container has a rubber seal and metal dish, was dry and swabbed with alcohol before use and dried again under heat.

Although it is damp with solvent in the photo it is dry now, just tiny tiny crystals.

How is the color looking? It's off-white mostly, some glasslike crystals but some yellow-ish areas too. The freeze stuff is constant off-white.

Color is not necessarily a good indicator of purity.. Check this out:

im sure you'll be fine

thanks mate, much appreciate. Might try to recrystalise a tiny bit on a small scale and see what it does for confidence.

Many thanks.
