qwiso problem

[bilbobonger]

Gray Wolf has a nice thread on a fairly cheap recovery still. Again, it's not perfect but it will save you substantial amounts of solvent.... probably be about as cheap as iso at that point.

Iso is going to cause you health issues in the long run. No getting around it. So sad that it's been so widely pimped as "THE" way to make hash oil and such. *sigh*

Stay Safe!

Thanks Hydro-Soil. I'll check out that thread. Definitely don't wanna be breathing toxins. So is BHO cleaner somehow? Been hearing a lot of negs about that as well.

 

[DiscoBiscuit]

Lol. People use iso to help evap off bho.

 

[bilbobonger]

Neither had i. Didnt even know it existed. Until i went to safeway.

And how does the amount of trays affect the 20 hours winterization? Granted, you probably dont need the full 20 hours, i just said that to be safe. You want to make sure the solution reaches proper temp, maybe GW or Jump could chime in on what exact temp that is.

Can only fit a few trays in the freezer at one time. Could see doing all this if I only had a few trays or so, but I don't have the time for that right now.

On previous runs I've kept things super simple, and have always ended up with great amber shatter. No white streaks or anything, but this is beyond white streaks. Looks like I've got a tray filled with watered down milk. For now I just wanna figure out what I'm doing differently and then stop doing it.

 

[StinkyGreen]

a couple of my trays are turning a milky white color. Anyone experienced this before?

I've seen this before. The white color went away after decarboxylating. The finished product was fine.

Thanks StinkyGreen. I'll give it a try. So for decarboxylation I just put the trays in the oven for 15 minutes or so at about 180F?

Didn't bother the last couple times. Never really made much sense to me if it's going to be smoked. Doesn't everything become active as soon as it hits the flame? Did it once when I was making tincture though.

Also, Waterbelly- thanks for the tip on the 99% iso at SafeWay. Will give em a ring tomorrow and see what I can find.

As mentioned, BHO boils off at a lower temp.
Essentially, heating it to vape it boils the rest off. Next to iso... I'd say BHO was pretty clean.... depending on the butane you use... lotta bad stuff out there.

It's also missing 'something' that I need for my head, when compared to the bud it came from.

Stay Safe!

Check the attached graph, compliments of Jump, for decarb curves,

 

[bilbobonger]

Thanks for the graph GrayWolf. I always thought going over 200F was a no no.

I know this is probably a stupid question, but just to clarify, this takes place after all the liquid has evaporated correct (can't see putting alc fumes in an oven as being a very good idea)? I'm only asking cause I saw a vid on here where dude was using a pancake broiler or something similar outdoors to help evaporate the iso. Putting it on ice, then in warm water, and putting it through multiple filters. Looked like a huge pain in the ass, just thought maybe this was what people were talking about with the heating and so forth. I'm really in no rush to get everything to evaporate. I'm just concerned with the end result.

Really appreciate all the info everyone. Thanks for the posts.

I follow the chart Grey Wolf attached above, doing ~27min at 250F/120C. I prefer the longer time in the oven as the curve is less sensitive to errors in timing/temperature.

You are correct that decarb'ing is not necessary if you are planning on smoking it though.

 

[Gray Wolf]

I set the container of oil in a 250F oil bath, and watch the bubbling activity. When the large irregualr bubbles are gone, the solvent is gone, and when the small equally sized bubbles suddenly drop off sharply, you are at about 70% decarboxylation on the graph. Bubble free is 100% decarboxylation.

Correct. I decarb after all the liquid has evaporated and the oil is just a thin residue on the pan.

If you bought your isopropyl alcohol as Rubbing Alcohol, know that the feds regulate its manufacture. Rubbing Alcohol contains ingredients to make it unpalatable, so hardcore alcoholics don't use it for a cheap drunk.

From Wikipedia:

"Legislation

In the United States, rubbing alcohol, USP and all preparations coming under the classification of Rubbing Alcohols must be manufactured in accordance with the requirements of the US Treasury Department, Bureau of Alcohol, Tobacco, and Firearms, using Formula 23-H (8 parts by volume of acetone, 1.5 parts by volume of methyl isobutyl ketone, and 100 parts by volume of ethyl alcohol). It contains 97.5-100% by volume of absolute ethyl alcohol. The rest consists of water and the denaturants, with or without color additives, and perfume oils. Rubbing Alcohol contains in each 100 mL not less than 355 mg of sucrose octaacetate or not less than 1.40 mg of denatonium benzoate. The preparation may be colored with one or more color additives. A suitable stabilizer may also be added.[6] "

Cool thanks SG- I'll give this a try.

Bubble free is 100% decarboxylation.

So you do this on somekind of broiler I'm assuming? Is there any advantage to doing it this way over putting the trays in the oven, other than being able to watch the bubbles that is?

Thanks for the info.

Correct. I decarb after all the liquid has evaporated and the oil is just a thin residue on the pan.

Cool, yeah, this is what I did before. Just wanted to make sure.

Thanks for the post CR-

Yeah, I'm with ya, I know the stuff's not suitable for consumption, but I've been under the impression that if allowed to fully evaporate there isn't a problem. Perhaps I've been misinformed though DK. Seems to be a lot of back and forth between the iso and BHO people. I went with the iso because I heard the yield was better, and I keep hearing more and more stories about people getting lit up with the butane. Smoked some though recently for the first time, and it did seem to have a better flavor in comparison to iso. Leads me to believe there probably are some impurities left over.

 

[bilbobonger]

I'll-be-damn, SafeWay does carry 99% iso. You-da-man Waterbelly.

Dip a clean spoon in iso. Let it evaporate. Taste the spoon.

Yes, you've been misinformed... as have millions of people getting their info off the net.

Now that you know, please take steps to switch to a food-grade version... yeah, you're going to have to change your methods too. Sorry.

Stay Safe!

I use a fondue pot full of 250F Canola oil. It works better for what we do, which is mostly oral or topical meds.

 

[bilbobonger]

Thanks again for all the info everyone. Will switch things up next time around. This run is what it is though. BTW, the white build up at the bottom of my trays did completely go away after putting them in the oven for a few minutes or so.

Actually BHO also has toxins in it depending on where the Butane comes from. Most folks use the canisters of Butane and while the butane itself is fairly safe the things mixed in with it as propellents to get it to come out of the canister, will turn to neurotoxins when they're heated to the same temps or higher as needed to vaporize cannabis resin.

Interesting, do these propellants evaporate out with the butane while purging?
