QWISO - White Powder?

Hey guys,

Sorry I didn't snap any pics but...

As a test I ran very small qwiso with fresh frozen sugar trim. It was about 1/4 of a 1qt. jar after grinding up.

Anyway, after evapping(over night with a fan over it), I was left with the greenish film I've seen before from qwiso but also 2 small areas of white powder.

My first thought was it looks kinda like mildew but I don't see how.

I used "frozen" 99.99% reagent iso, not sure exactly how much but just enough to cover the trim, I poured it thru tippled coffee filters(store brand white). And I QUICK washed it best I could, poured the iso in, shook it once, then poured thru the filter, no pressing really. The resulting liquid barely covered the bottom of the pyrex pan.

PS, Temps are ~70, and RH ~30% where I was evapping. It be cold and dry here, hehe.

I'd be interested in an ansewer to this as well. I have done qwiso countless times, never an issue, and it was all from the same 5L bottle of 99.99%. But the very blast time, was just a little bit inside a large grinder, and I poured it onto a piece of glass and let evaporate, and for the first time ever, was left with a large quantity of white stuff, naturally I scraped the whole lot into the bin.

I have had iso extractions let have ended up a white powder. This has only happened to me with pure sativa strains. Qwizoking may be able to add more to this answer as i've heard tales of most of his qwizo extracts looking this way

Well that might make since considering I followed some advise he gave me, lol.

PS> Its Blueberry, unknown exactly what one but heavy Indica for sure.

Yea tc or war machine..idk? Brought it up a while back in the iso thread...it kinda freaked a few out ..

Heat the white powder or compress it and it will look like the rest.. generally people find this white(not always white) powder on the sides of the dish. It likes to form in the azeotrope as the hash is falling out of solution..the slower you evap the more you get(especially with a good fan)
I never heat my hash and end up with what you describe..all of it ends up as white powder

Perfectly normal..and I consider "powder" to be the best quality
good job.....(course without pics....)

Compress between a blade and it should do that

I had a whole batch of tangerinepower oil scrape into white powder, and when I pressed it it became a stunning clear yellow probably some of the nicest I've made. It is complete shatter at room temp, and tastes just like the buds smelled when I cut them.

Cool, thanks.

Like I said it was 2 small areas, maybe 30% of the surface area. Rest was greensih.

I didn't have a razor so I used a lil triangle thing and scraped the powder and the greener stuff, the green truned to sort of a light brown powdery as well but was easer to manipulate. It was hard to actually get the powder to stick but mixing with the green stuff helped.

I just used my fingers to press it together and check it out. Ended up about the size of a cannabis seed actually. I trashed it and washed the dish in prep for a pop corn run, but I've got to trim the rest of my crop tonight so yea, prob be a day or two.

BTW, for the best product. Should I grind up the frozen popcorn or just run it? I don't care about max extraction really.

I'll bare this in mind for the future, but in this instance, there was no where near enough anything in my grinder to produce as much of the white residue as there was. I did it more for cleaning than to obtain a return. There was maybe about the equiv of a grain of rice of kief in the grinder, yet upon scraping the glass, there was a good table spoon and a half of the white residue.

The less cuts the better
If its thin and larfy I will run it whole...I don't run indica though..yours may be too dense, you don't wanna break it up when its all said and done and find whole trichs..can't re extract(cleanly)

White is typically water solubles, so look for sources of water. Was the trim also frozen?

70F is actually warm and 30% RH enough to pick up water using 99.99%, which is ultra hygroscopic.

Well, yea, I mean it's cold outside so the heat is on making it even dryer indoors. I did it over night in a small unused spare half bath with a small fan over it, exhaust fan on, and door closed. Heat was on like 67-68 overnight prob so I said ~70.

Everything was frozen at least 48hrs. The trim, the jar before the trim was put in, the iso, even the "ninja" grinder I used to chop it up was frozen. (well the blade and container, motor is a separate piece.)

PS> It's like 0-20F out side recently, should I just stick my iso in the snow out back? lol. Seems that would be colder than my freezer, albeit less stable.

Having the heat on indoors, doesn't necessarily lower the humidity, as the warmer air can hold more water and there are multiple water sources in a house. You may have to measure it to see if it is a variable.

Another thought though! The amount of water solubles extracted is a function of contact area and time. Grinding the material exposes more broken leaf boundaries, and therefore more water solubles. We lightly break up our QWET/QWISO, but don't grind it.

If you always grind, the rest of the process hasn't changed, and this has only turned up this time, I would take a look at what might be different about the material. For instance, was it flushed before harvesting.

Well it does here, hehe. Last night is was 4deg outside 88% humidity, It was 68 inside, 11% RH, hehe.

And thanks for the info and advise. It was flushed btw.

Im with Qwiso. I get white powder with clean quick washes. Go a little too long and you get the goo. Both are good, depends on what you are looking for. (quality overt quantity)

It's most likely atmospheric water that has been introduced. When you dissolve the oil in alcohol and then introduce water it will turn white. AKA the Ouzo effect.

Latest run produced a lot of white powder after full evap, At least 12 hrs with a fan over it... Got pics this time!!

This is actually the 2nd run in this pan. Meaning I ran a wash thru it a few days ago and scraped and covered the pan without cleaning it then ran this wash last night...
