I'm trying to find a Pyrex/borosilicate that would be of good size for this and would hold up to the heat of my hot plate. Do you have the size of the one you're using when doing a batch around the size you posted in your tutorial? Wondering if you could share a link to one, seems that some are now built with Lime stone or some other material and they shatter so was wanting to find one that would not shatter and would be safer to use with my hot plate.

Oakley, I like how you are running this post. Good job.

I am interested in making topical for pain relief. I am going to use fan leaf and stalks to start. Also going to look into trying the roots. I may later run low grade buds.
I have soaked fresh leaf for days, yes very green!
I used stalks and did the quick wash. Very nice amber color.
I do get nice pain relief from doing this, something along the line of ibuprofen or aspirin. Didn't notice alot of difference between the two.

I would like to try your method and when it is reduced as far as possible, work some coconut oil into it, and bees wax.

I am hoping that concentrating it will increase its potency.

Anyone, any thoughts. Thanks

Oakley,
Excellent post. Your knowledge of the fundamental principles behind your work show through loud and clear. I have a couple of questions for you.

1. While you do heat the solvent in the final steps, I wonder if you are making a point to reach the temperature where decarboxylation of THCA occurs (50°C ) without boiling the ISO (82°C) which would also boil off some of the more volatile cannabinoids (CBD in particular). If you don't get it this hot, do you a recommend decarboxylating step prior to freezing the plant material in preparation for extraction?

2. Do you see any advantage to "super chilling" the plant material and ISO to -80°C using dry ice? I know you talked about it before but i wasn't clear on your final verdict on whether this would be beneficial. Further, if it was "super chilled" would that alter the solubility of the cannibinoids in ethanol significantly? I imagine this would alter the exposure time needed for the highest Cannabinoid/Chlorophyll ratio. Would this prolong the exposure time? Would it allow for some mild agitation to increase the number of trichromes that make it past the filter into the next step? I know you are anti-shaking but what if super cooling could allow for that without picking up more chlorophyll? Would the color of the filtrate be a good indicator of when to stop contact between the plant material and the ISO? For example, i would continue to pour some "super chilled" ISO through until it reached the very slightly green color in your original post.

Any thoughts are most appreciated.
Thanks,
TK429

Hey Oakley, great job on the tutorial man.....I have a few questions for you.I have never made iso before but have made BHO and Bubble.
So this would be my first time making ISO.
#1> using the ratio of 1OZ of trim to 1 litre of 99% iso, how long should this cook for?
#2> How do you know when the ISO is finished cooking off and ready?

Thanks bud.

I have not finished reading the whole thread yet - but Oakley I have a question - would using ice wax(bubble hash or whatever you wanna call it) in place of bud result in a much higher yield? also - if using 91% and using bubble hash wouldnt you have to wait for the extra water from the bubble hash to evap off so using a 91% alcohol the 9% water will go with the water from the bubble rightl?

So say you are getting around a 20% yield and you use 28 grams(1 oz) you would end up with 5.6 grams of oil right? so say you have about 28 grams of ice wax, would that result in a closer to 40/50% yield?
Thank you for your time

your theorys are correct for the most part... keep in mind when you use bubble/crystal to make oil with you will end up with a MUCH darker product!
and i wouldnt use bubble that hasnt been quite literally overdried, try dry ice hash, should work much better !

cooks for as long as it takes
and, it will thicken down at the end... use your nose! the smell of iso is pretty noticeable.
soon ill be putting up a full vacuum purging demo of iso products as well to yet again increase quality.

decarbing is more of a step for cooking than concentrates from my knowledge... i have never deemed this as a necessary step for extractions.

dry ice isnt readily available to me so i have yet to play with this side of things... my personal believe if i was going to use dry ice and iso for an extraction, i would try a stainless steel pressure cooker, put dry ice and iso into it, seal up lid and either wait for the co2 release of the dry ice to reach pressure. or manually pressurize it. still limited contact time tho, 60 seconds or so.

the agitation isnt going to help extract what you are really looking for... pressure however will help penetrate into trichomes of all kinds, bulbous, non bulbous, stalked etc... and allow for a more complete extraction.

how did it come out? Im using 91% iso and its on the hot plate now. Seems to be taking forever to evap and its still really clear looking. Hope there is something in the alcohol...
