Hello! SWIM recently completed Cyb's salt tek, and SWIM is now at the point of freeze precipitation. Unfortunately SWIM feels rather worried that there is something unclean in their product. There is a residue that surrounds all the crystals currently growing. Does this look normal? Or does it look like they pulled some crap as well as the deemsters?

Thanks a million fella's, appreciate you taking the time to consider this dilemma.

I'm not sure but it looks like your non-polar solvent isn't evaporating clean. What did you use? Cyb's tek calls for naphtha but there are a few different brands...

Klean-strip VM+P naphta from Lowes. Odd thing is, an evap test came out clean.

SWIM said they will do a second evap test now, hopefully it comes out clean! Any other possibilities?

I would suggest heating some naphtha slightly to about 100-110 F and dropping all the spice in, stir it let it dissolve and the remaining solids float to the bottom. then pour it off into another container witha coffee filter on top, if need be repeat this until its more white then yellow, some yellow is alright but I agree that looks fairly unclean what does it smell like does it smell like the solvent you used or like flowery plastic?

IF YOU CHOOSE TO HEAT NAPHTHA BE CAREFUL HAVE A FAN TO GET RID OF FUMES AND DON'T USE AN OPEN FLAME USE ELECTIC HEAT AND A WATER BATH TO HEAT IT!

You hit the scent description on the head of the nail. I was trying to place it, it wasn't nafta for sure - that's it, flowery plastic.

Should one go ahead and do what you described?

If you feel confident and comfortable in slightly heating naphtha. I can say I've cleaned brown/red spice to a white color as I said but only do it if you're comfortable and understand the dangers of heating a solvent with volatile fumes.

Would it be better to dissolve the product in the glass dish back into my next pull of the rather unpulled basified mix?

Only one pull has been done of 50g of bark split into to separate extractions due to vessel volume limitations - each tray has each first pull from both mixes. I feel I put around 5-10% to much of everything else on the first extraction, which happens to smell cleaner. The cap was of the metal variety and the bottle was a thoroughly sanitized Arizona glass bottle (519ml) and the separation vessel I used was a glass Jones bottle(355ml), also sanitized thoroughly.

Do you advise SWIM should go forward with re-x or should SWIM combine and pull 4x?

This looks perfectly normal to me.
The 'residue' or clear oil should be scraped up with the Xtals as it is active. It's pretty sticky and hot solvent can be used to get all of it.
Re-x everything with hot naphtha or heptane and you will be fine.
A carb wash (while in the naphtha) can be done if you want white Xtals...but some prefer it golden.


You most likely heated the mix to much or left the pulls in to long...this usually causes the heavy yellowing.

Can't thank you enough for the response Cyb - You're the best.

SWIM scraped and dissolved as much of the dirty product they could into hot naphtha and filtered it down twice, then combined it with a second milky pull (much cleaner) which is now in the freezer at lowest possible temperature.

When I dissolved the product into the heated Naphtha large stringy black chunks of material sunk to the bottom - this was likely basified mix I had sucked up by accident. I feel the currently crystallizing pull is much cleaner.
