I may try hexane next time. It is definately cheaper can it be properly purged without vaccuum?
Hexane does a fine extraction, but despite its lower boiling point, it is harder to purge below the 130 ppm sensory perception levels than ethanol. Before using vacuum, we used several ethanol washes to tease the last bits of hexane out as an azeotrope.
Try letting it evaporate with a fan directly on it and no heat. You will be able to manipulate the end consistency more. ISO will evaporate 100% on its own and then can be vac's or heated for consistency.
I am having the same problem, it makes me use the basic single picture up loader. A couple of days ago I was able to upload multiple pics, now I cant. Maybe something to do with the site?
Yes its white when you have very thin layers of it with very little lipids and whatnot. If you want; you smash it all together and vac it too. It's first form will be the shatter you are used to; I continue to vac for cheese like stuff.Interesting. I may try that on one of my nexts runs to see.( Im an impatient mofo, so waiting 24hrs is painstaking for me lol ) every pic ive seen of people doing the long air evap method, always seems to come out powdery/dryish hard to scrape hash. i scraped mine around 110 so it was all a nice consistency. But i will deff try it out during a next batch on one of the washes as a test to see.
It seems like my #1/2 is actually staying slightly taffy. no fine breaks/snaps when i bend it fairly well.
suprisingly i forgot that i had poured even a 5th run for the hell of it. looked slightly green so i said fuck it. went and looked at it today and it air dried out, so i heated and scraped. to my suprised it was a nice golden still. i piled to middle and heated at 120 for 30mins then scraped. its a nice bend n snap now. warms in finger and can get a good pull. im satisified for sure!

Hey guys I get the white powder every time the tane extract is super cold and ambient air is very cold out and I use no heat at all to evaporate the solvent. And the oil always seems to be a bit lighter in color when made this way. It's a tricky thing to add just a bit of heat while evaporating the solvent to keep it from going to a large white powder mass and still keep it a nice light color. But if I am doing large runs and add a bit of heat (around 70F) or so then the oil will slightly darken up a bit prior to the vac purge. Bit of a learning curve to get it to not powder up while still keeping the temp of the extract very low.BlueJayz said:
Were talking about ISO buddy...

Large run extracted at very low temps with no heat while evaporating the tane:
Note: there is still lots and lots of solvent still in the white powder concentrate. Pressing it between your fingers and getting it a bit warm reveals a strong butane smell and when further purged lots of gas still purges off of it.
