qwizo's qwiso

Yea, I get people asking all the time how I make my qwiso and questions about it. Guess I'll finally make a thread..

So a little backdrop on the solvent. Basically its hydrated propene, in the production nothing nasty is created. Its completely clean. Rubbing alcohol is typically 70% to reduce skin irritation, its often denatured as well, meaning crap added in.
We want to use 91-99% Iso. both will make a great product.
Because iso is more water loving than butane it extracts the compounds at different rates giving different ratios, this is a good thing.
But it will extract a lot of undesirable compounds if left in solvent too long.
At the same time a straight up pour through like bho is not the best way to go, you lose alot. I recommend about 20 seconds total but you can go to 45ish and get a really nice extract. yes multiple stages of filtering is required. Start with a large mesh obviously

The solvent isn't terribly dangerous and can be done indoors no problem with some light ventilation.

Ummmm
For a basic qwiso you can do fresh frozen or dry. There are pros and cons for each..generally you want the fewest cuts in the plant matter still allowing it to reach all the trichs.

You want everything as cold as possible except what your gonna evap on to prevent condensation. If your gonna go fresh frozen, chop with frozen whatever (i use scissors) and don't do till the herb is frozen.

fill a mason jar and swap the inner lid with some type of screen to hold back most of the plant matter.

1 bottle will fill a jar about 2/3-3/4 to the top of the bud line depending on density. Fill to bud line, give it a swirl. Pour it out. You want one more smaller filter preferably before you hit coffee filters. 2 stacked coffee filters, no more no less. Every process in this extraction is as simple or as complicated as you make it and makes a difference in the end. You could finish with a micron syringe at this step for example..this is the basics yea.

So you got your filtered iso wash, you wanna use no heat, to evap ..none..
If you don't know why go microwave quick dry some of that herb before you fresh freeze and taste it.
The slower you evap the more lighter compounds are
retained, which are flavorful. Vapor pressures increase non linearly with increased heat and the ratios of what's leaving get closer together.

When the solution is evaporating if you add a fan to speed it, you will notice a white ring appear around the dish. Its normal and when dry will just be oil. Fancy word for it is azeotrope. Its just the Iso and water in a happy little group evaporating together.

When the dish appears completely dry wait 4-6 hours then scrape. That kinda depends on the thickness. You want as thin a film as possible. 1 mason jar will do a pyrex nicely.If your scraping and its opaque and creamy or multicolored it may be under purged. Its easy to tell by look.

Iso is much easier to purge than butane

When you scrape, it should be powdery on your blade. You can press it with slight heat and get a clear shatter or more goop depending on genetics.

Never pull and snap or taffy. That's not cool

Early harvests are good

That's all I can think of.. so nobody should have any more questions for me

sounds pretty standard
I do mine pretty much the same
but I use a thermos instead of mason jar
and do a hot water bath at the end prior to scrape

so you just evap, scrape, than smoke..?
no hot water bath or forms of purging..?

not saying it needs to be done, just curious

nice thread glad you finally got around to it

Well this is proper qwiso at its most basic

I usually start at ~ 78° and let it sit and conglomerate.

a good 12 hours is needed for my desired product. as it reduces I drop the temp to ~50° just before saturation and add a fan or slight vac. I then steadily drop the temp to ~30° as it precipitates

No I don't heat purge but if it makes you uncomfortable once it appears dry you can melt the oil right quick.
Its not necessary though

Problem I have with a thermos is the material its made of. Iso is fairly reactive with like aluminum and I'd just rather tell people to use glass, avoid any nonsense

That reminds me.. might as well mention, you shouldn't buy large quantities to store long term.. or gallon jugs if your not gonna use it all

sorry I said standard because I knew you were more specific on temps

what's the point of dropping the temps under 78 when you are evaporating?
or am I misreading your post

I can get it to fall out of solution crystalline.
Normally when you evap and its done it appears as a thin golden film on the pyrex you then scrape up (which often will be as a powder on your blade) but it isn't stable in that form and simple pressure from scraping will solidify portions into shatter or whatever

When I do it, it falls out of solution as white crystalls that are quite stable. i can keep it in that form and people in my area go crazy for it..

This is a perfect example of when I first saw it. The oil film on the left and the obvious powder on the right I drew a couple lines in. The right side had the fan blowing on it more.. I had to scrape up the oil on the left, powder on the right I just scoop. After playing with it for a loooong time I can get it all to fall out white crystals. Like that "meth" pic I put up recently

Still loving the pink hue on that

i do my actual wash a little different but more or less similar tek. also evap w no heat. sometimes if i do a 2nd wash i will use a seedling mat to make the iso evap a little quicker but not too often. when i scrape and get my crystaline powder i dump that into a parchment paper then hold between my hands until it melts into a shatter

This is a coincidence bro!I tried to pm you but it wouldn't let me,so I said fuck it.I'm sure I'd see you around.I was gonna ask if you use coffee filters?
That meth looking scrape looks really "pure" ..good job!
I know the cooler the temps are when I scrape the harder the hash,which in turn creates a more powdery,whiter product.The longer it's stored at room temp the darker it gets...

Do you think you lose product in the paper filters??

.......any way my question was answeredI know we've talked about our procedures before but you know....I forgot! This is my last batch even after I scrape all of it together,even the golden sticky stuff on the sides

I wanna say here lately I've been using a gallon storage bag instead of the jar.Just cut a small hole in the corner to drain the iso wash(not too big to allow a lot of material thru) thru your choice of filtering method. It allows me to do a quick wash with a small amount of iso that gives a purer wash that evaps quickly,due to the small amount of iso used.Then I can do another wash with a 16oz bottle of iso that I'm able to squeeze all the goodness out.Have a good one guys!

interesting, ill have to shoot for that crystalline consistency on my next run

what are you using to control these low temps during evaporation?
and how are you preventing condensation? (if any)

why would you want to possibly scrape powder?

its what I accidentally get at the veryyyyyy top of my dish after spraying where the oil is extremely thin. pretty much just a back pressure spray mist. I fuckin hate it. heat the dish up a hair, melt that powder dust to an oil thats possible to handle, and youll probably enjoy scraping a lot more.

what do you do with that powder?? surely it cant be smoked on the nail in the powder form and needs to be turned to oil/shatter anyways??

When I scrape my powder I just use the heat from my hands to mold the powder into a easy to handle piece if that's what I want. Sometimes I like to use the powder as is. I love variety and trying things different ways so I play around with smoking it.

Ummm, yea y'all can figure out an easy way to control temps, I do it in here and behind that door. "Piping" fumes out. I don't worry about condensation, its not an issue until you get out of the cold. I filter and everything below freezing..


you do lose a bit in the coffee filters. But its such a small amount, not noticeable IMO. But my filters do usually smell good and are slightly sticky..so 2 filters, more won't really filter more..

Yea my inbox has been full for a couple weeks and I can't delete from my phone on the new site layout.. I doubt I'll make my way to a computer any time soon. I don't do internet or tv etc..

the crystallized hash is easily handled as I mentioned the powder that naturally comes from scraping is different and not stable. But again I don't have to scrape, I can tap the hash out into a container. Typically I gram it out and people stick a dabber deal in and scoop the crystals, it doesnt cake too much and is stable up to about 100° i can get quite large crystalls these days, people often view this as a sign of purity. And being that im almost certain nobody else sells a product similar, it intrigues most....but yea its certainly smokeable and huge dabs will burn much nicer

Just realized that first paragraph doesn't make sense tx..
I do all the filtering and stuff below freezing, really helps. But yea it has to sit and do its thing for at least 12 hrs. During which time I bring it to room temp,and no you can't just let it sit while cold, though that will make a nice product.. water does condense but its not gonna matter really especially in our environment a little water won't hurt anything really anyway, why I didn't say only use 99% also. Then after its sat around I stick it back in there to chill...

I want a walk in cooler so bad QK!! Nice pics buddy.

I just finished a "B" grade batch this morning. Turned out pretty nice. The A grade will be evaping tonight after some company leaves. I've got a nug run to wash later too. Qwiso is great, we took some dabs while tripping a few weeks ago .

nice! now I am jealous lol
I don't even have enough pyrex dishes to fill up them shelves
let alone product
very impressive my friend

Well, I am glad you wrote this up. I've done a couple BHO runs but don't have a vacuum purge or anything so I switched to Ice Water Extracts. Buttttt......

I have a couple oz. of my first run bud that isn't very good. I don't really want to take the time to do a hash run with it so I was thinking the next best options would be qwiso.

Will be doing this tonight.

I have been doing this way wrong. I was told to let it soak in iso for a few weeks then filter it and let it evaporate, then you get a sticky black mess that smells like hash and chlorophyll. It took a few more weeks to evaporate I guess because of all the extra crap it pulled out. So it only takes you 12 hours to evaporate?

Thanks for making this thread. I saw someone on here say it should be a quick wash so i looked for instructions but couldn't find any. Im gonna have to try doing this the right way. powder looks a lot better and more manageable than the resin like stuff i ended usually with.

One 32oz bottle of 91% iso ina 9"x13" Pyrex dish will take 4-5 days at room temp(75degrees,50%rh) to evaporate.....at least it does for me

....and DAMN,farm a few weeks soak!The difference will be night and day!Do a quick wash....45 seconds at the most.Trichomes almost instantly dissolve into the iso.GL

With a single bottle and air blowing over, roughly 2,000 cfm at about 77° .. I'm normally scraping in about 26-28 hrs
