Goryo, I went searching through my notes and wandered around the Internet for the greater part of the past couple hours and this old conversation from bluelight.org captured what I believe is the best recipe I've seen for making oil from hash. I left more of the conversation intact because pasha makes some good points.

"I want to carry out an extraction on some mid grade un-adulterated hash from Morocco. I say mid grade because its not bubble hash or isolator or anything, just nice quality solid. Anyway my point is that I want to know what would be better to do, Butane extraction or isopropyl extraction. and what sort of yield would i be looking at from doing that, considering the starting products and appropriate extraction method.
Any wisdom?
Thanks"

"I just turn my hash into oil in a few easy steps. I don't bother freezing it or putting it in the oven or whatever else I see on recipes.
1 - crumble the hash into a jar
2 - add iso until the hash is covered
3 - shake for 30-60 seconds
4 - run it through a coffee filter
5 - let the iso dry out
For me, the yield usually varies depending on the amount of time I've let the hash sit in the solvent and the quality of the hash."

"what sorta yield would i expect from let say 100 grams, on a good day?"

"It's really difficult to predict. The oil is basically what holds the plant matter together. The higher the quality, the more oil you get.
If I have good hash I usually get a 15x15 cm square about 1/4 of an inch thick of oil. That's from a 200 milligram slab of hash. If you do the process right, which isn't really difficult at all, you should get pretty much everything. So by weight I'd guess it'd be about 120 milligrams.
If you wanna be absolutely certain you get everything shake the hash for the full 60 seconds. You'll get a little bit of plant matter as well but you'll guarantee that you have all the oil.
I suggest you try doing a small piece first. Or several small pieces and experiment until you find the right method. That's what I did until I found the perfect way to do it with the hash I have."

You want a solvent that's 190 proof or better. You're in Germany, which I believe means you can get ISO that's 99% and is much purer than we get in the states. If you're using ISO, I came across an interesting technique where the hash was placed in a coffee filter and then submerged in enough ISO to just cover it.
From THC Farmer:
pugliese63"I've done something very similar with both dry sift and bubble. I used 99% iso alcohol which you can usually find at nail supply stores. I took the hash, placed in a coffee filter and submersed it into the iso. I gave it a minute or two just to make sure it was dissolved and pulled filter out. What was left was a minimum amount of what would be described as a cork like material. I purged/evaporated it on a heating pad and then let it finish on its on for about a week. I'll agree 100% with SCFSYNDICATE760, it produced some of the smoothest and strongest concentrates that I've been able to make yet. No residue at all. Has a beautiful caramel like consistency and look."

Evaporating out the solvent can be done as easily as using a double boiler, the same way we do with our bud washes. This way you can watch the solvent evaporate off. The bubbles from the alcohol are larger and more sporadic in size. The bubbles from decarbing are small and uniform. If you're shooting for the highest level of THC you want to stop just as the solvent has been purged and the bubbles are all small and uniform in size. This is impossible to miss. Don't stress about absolute times here, just keep an eye and pull it after the bubbles have all obviously changed in size. The oil's a bit runnier at this stage than if you let it go through the entire decarb, until there are no bubbles at all.
This will give you basic oil. If you choose to use some of that to create capsules we have a recipe for making them much more bioavailable so you don't lose 80% of the cannabinoids through elimination and metabolization. Using suppositories you're already more bioavailable, because they're made with coco butter.
Badkittysmiles has a recipe for making oil with hash and filling capsules that uses a carrier oil and lecithin to speed absorbtion and increase bioavailability. Reading over that for the hundredth time I can't help thinking there has to be a way to make suppositories that actually hold together using this addition. Chewey tried and couldn't get it to work and then his friend passed away and we stopped trying. I think I'm going to have to make more oil myself and play with this process until I can get it to work. The lecithin is too valuable a component in this process and I agree with BadKitty, it should be included on some level with all cannabis recipes and concoctions.
With Chewey we settled on as little as 5 grams of lecithin for every gram of CCO, and that may work well with suppositories. If you want to experiment with this get liquid sunflower lecithin. I don't have enough oil at the moment to experiment myself, or I would. As soon as I can, I'll get on this project.
I have a gram of oil in storage. Maybe I'll pick up some coco butter and make a partial batch. I have no need for suppositories myself, but I haven't tried one yet and that's kind of what the study hall is about. Then I can put this confusion to bed once and for all. Alright, I convinced myself. You make oil and I'll play with the suppositories and lecithin to see if I can stabilize the mix. Then I can share the results with you. Deal? I won't waste anything because what I can't use for suppositories I can put in capsules or turn into smoothies.
I hope this is useful for you. Please don't hesitate to ask any questions. In this room more so than others we encourage questions and revel in seeking out the answers. Well, I relish that.
I don't know if I can speak for the rest of the crew, but tracking down and making all of this information available and easy to understand makes me a bit giddy. Lol!
Ok, I'm dead tired now and it's time to climb into bed. Thank you Goryo, I learned quite a bit digging this out for you and I'll finally have some workable answers to the process of incorporating the bio bomb to suppositories.
We wouldn't want them to have to widen the doorways so your big head could get through. Humility is a good thing.
