Can I get some feedback on this idea?

So I want to make qwet but instead of jars and swirling I want to just pour over.
I am freezing 80g flowers, 1.75l of ethanol, and the metal strainer.
I figured if I put the frozen flowers in a frozen metal strainer, and pour frozen ethanol over it that will be super cold to lock up chlorophyll. Ill have a strainer underneath with an un bleached coffee filter as you can see to trap any particulate that flows through the holes.

Any thoughts? Any tips? How much ethanol would you use for 80 grams of flowers? I figure the more the better to make sure I get everything.

my thoughts:

we use columns when blasting bho to get good surface area coverage..

people do the soak method in containers with butane, ethanol, sometimes multiple times, to get best yields..

i feel just simply pouring your ethanol over will produce low yields, but probably a good end product after fully purged.. . just a very inefficient system..

Could I re-pour the filtered liquid over the material a second time or would I lose out? I've been getting around 10-12% yield on my material with butane. If I can get similar yields and a good end product I would like to stay away from the tane.
I have a high power microscope, so I plan on making sure everything is extracted.

I would like to move away from butane. Every time I blast I keep asking myself if this is the one that ends me

i guess you could.. just keep everything very very cold, like freezer cold. and ya, cold...

spraying butane requires the right prep work, and a good head on the shoulders.. if you aren't doing it int the right place, then ya, stop..

i feel more scared pumping my gas at the gas station..

you will definitely get something. Me personally id do two batches one in which you had said and another with light.."light" agitation. LIke you said swirling method. In my opinion anything after that is deemed nastyy. Im a big fan of iso.. if you check out my thread you will see.

Full on Joey Lawrence "Whoa!" LoL

Ive got a very good head on my shoulder, blast outside, prep and plan like crazy. I'm a professional fine dining chef by trade so mis en place is everything. I heard someone in the town right next to me burned their place down. That tells me two things. One, they're a dumb ass, and two, they blasted inside. I do it the most careful way without having a Tunisian extractor.

Im mostly worried about static electricity. Has anyone ever used one of those grounded bracelets that computer techs use? It grounds any static shock so they don't short any sensitive electrical parts.

Why do you like ISO better than Ethanol? What's the advantage? Ethanol seems like the best most obvious choice IMO.

I wouldn't worry about blowing yourself up. Not if you follow proper protocol. Speaking of which I ended up freezer burning my hand on the butane last time I blasted AND I was wearing an oven mitt. If you're trying a new method that's one thing, but if your scared of butane that shouldn't be the reason to stop blasting.

I dont prefer either or like ISO better. Just very comfortable with ISO and therefore am a fan as i said before. But I have not looked much into ethanol. All ears are open. I will say I like the yields and the results I get from ISO, as well as the easy access to it.

Pour through works and can produce a pristine extract, usually at a lower yield than a soaking procedure. Soaking wets all surfaces and pour through can find the easiest way through. Pouring even more through, just follows the same path.

Stop pouring through when the exiting alcohol clears and isn't sticky to the touch after evaporation.

After reading Oakley's ISO tutorial I am going to make some adjustments. For one, I feel the coffee filter underneath at this stage would be a disaster. The amount of alcohol I am pouring through will be way faster than the filter can keep up with and I will have overflow. Two, he said a liter per ounce. With 80g, 1 liter isn't going to cut it.

I am going to instead pour through 1 liter into a frozen large Pyrex measuring cup. Then place a second one underneath and pour the same liquid through again. Then I am going to finish by pouring a new frozen second liter through to wash anything left or trapped through. From there I will filter it through a coffee filter with activated charcoal.

After looking at it through a microscope if its not fully extracted I can always make RSO or tincture with whats left.

Should I pop it in the freezer for 48 hours and strain again?

evapping ISO fumes indoors, or outdoors for that matter can be just as dangerous, as well as get you drunk and fucked up if you happen to inhale some.. butane doesnt do that.

and when spraying butane outdoors, if you use cold butane, it will stay liquid longer.

if you use warm butane, theres butane gas everywhere WHILE youre spraying. it usually dissipates and thins out so quickly, that it wouldnt light even if you tried (as long as youre outdoors with a tiny breeze)

I spray with cold butane, then set the dish into a larger dish and go inside as it cooks off... if something were to blow, THIS is when it happens, not while spraying. and thats why I go inside, just in case. everything has to line up just right for there to be an explosion outside. butane sinks to the ground, and dissipates in even the tiniest of breeze. its really not that scary if youre doing it alone, and outside.

I know guys who worked on the road... would make BHO in their hotel bathroom and evap it off in the bathtub with door closed... walk in bathroom with a hoody on backwards with hood over his face just in case it did ignite... stupid, but did it for years.. if he doesnt blow up in a bathroom, youll be safe doing it outside for the most part.

ps: I know another guy who blew up BHO in a bathroom... blew the hinges for the door right off the wall, melted his pants to his legs, and lifted the ceiling off the walls... top of the wall was all cracked and busted.

Oh Vac you make me feel so much better with your stories of melting pants, exploding doors, and cracked walls!
i freeze everything including the container I blast into with BHO. I let it evaporate outside until thick then add ethanol and cap it for the freezer. I'm def being as safe as I can be.

Ill never use ISO as long as I can get good quality ethanol. I'm so new to all of this I'm still finding my way. I appreciate everyone's time to comment and help me out. Big ups for the RIU community!!!

lol I know I know!!! im not gonna sugar coat everything and make it sound like its guaranteed safe. it def has its bad point and I def know of some horror stories. but like I said, he was doing it in the bathroom, and I believe he flipped the fan on half ways through... if it had been on from the start, it might not have done that.

we know better... cold butane, middle of the yard. no one around just in case.. while its evapping, stay away. dont need to be sitting there watching it and possibly breathing in the butane fumes. plus, if it ever did explode in the middle of the yard, depending on the yard, no one will get hurt and no damage done... just a 8 foot flame coming from your dish until the butane is gone, and yes the oil is smokeable after something like that... dont ask how I know

just be smart is all. most people that explode are doing something very stupid. sounds like you know what youre doing, and with that you described, could blast weekly for 50 years and not have any problems.

its these guys that think they can sneak a quick smoke while its evapping, or doing it near the house with the door open a crack so they can watch. not good.

Sounds like decarbing the hard way!!! Lol

So I went for it with my minor adjustments. I have to say, it worked out beautifully with one exception which was getting max trichomes removed. I still got a 10% yield, which was what I was getting with butane before. So I didn't take a step back in yield but I know I could of done better. Plus side is I still have the material frozen, which I can make tincture out of later. I also reduced the liquid in a non stick electric pan instead of a hot plate and pyrex, then transferred it to a non stick silicone baking pad where I vacuumed it while still in liquid form under low heat about 90-100 degree F. Not sure if I'm a fan of the silicon molds or not yet. The more vacuum time the better. If I went for full 100% wax and dried it out completely, I'm sure it would be excellent but I like my stuff a bit sticky so it dabs easier.

Method: froze material, ethanol, and equipment for 1 week. Added material to strainer and poured one liter over recapturing underneath with a frozen large Pyrex. I then re- poured the liquid over 5 times repeating and finished by pouring a new bottle of frozen ethanol to wash everything through. I then strained it through a coffee filter and then added it to my electric pan. Reduced, then added to a silicone mold, under vacuum and low heat until thick, then vacuumed for 24 hours. Pics are as follows. Material pic after first run to see its not completely stripped. Ethanol in pan reducing. Silicon vacuum. Sap after reduced fully. Finished product after 24 hours vac.
