Absolute separated from Concrete?

Thanks for the correction with regards to the terminology. I too read the material that came with the unit before doing anything, but that was a while back. I have used a carrier solvent run with the primary solvent (Everclear and Butane together), the result was very dark because the alcohol stripped more chlorophyl.

I usually use Everclear as the transport solvent, if I use a transport at all.

If you filtered the Transport solvent somehow to remove the waxes, you would be left with the absolute (as I understand things). The transport will also make recovery of the butane easier.

I did a soak for five minutes on that run because I was experimenting. I have done long inversions and short ones. I have also done the short burst method, I've done it under pressure (350PSI).

The short burst gave an initial product with less waxes. It looked like cleaned Concrete actually. This is because of the short time of exposure limiting the amount of wax in the end product.

A long soak will give you a dark product, and one that may taste very bad, but it may also be the most potent extract you've made.

The longer the solvent is in contact, the more stuff gets extracted... good stuff and unwanted stuff. You can then clean up the dark, high quality concrete and end up with golden shatter of the highest grade.

That is what I meant earlier when I said dealing with the gas companies can be a pain in the ass... I just gave up and first experimented with Vector and King brands that I first cleaned by doing a dry run.

I have not been getting back all my butane every run. I am anxiously awaiting the release of the Rotary Evaporators and Chilled Vacuum chambers designed for 100% recovery. I just wonder what that will cost. Anyhow, I would be cautious about using your expensive, pure gas from AirGas for your initial experimentation.

This thing is really all about experimentation. They list the variables, you choose how to manipulate them.

I took my blob of black concrete, dissolved it in Everclear, added Active Carbon, and allowed it to settle at room temperature. In the photo below, you can see the Carbon on the bottom of the glass. In and on the carbon layer is a layer of waxes and other shit (still learning what that shit is). Above the wax layer is a clear golden liquid. If this liquid is removed, leaving behind the waxes and resins, and the alcohol is evaporated off, the result would be the Absolute. That is my understanding so far.

Here are some Photos.

Butane extracted Concrete (usually ranges in color from blond to black):

Jar with a bottom layer of active carbon, the grey/white layer is the waxes that have precipitated out of solution. In the past, I have seen the waxes separate out, but they remain suspended in the solution. I'm guessing any condensation nuclei would work (sand probably does the same thing) if you don't have your hands on carbon.

Above the grey band is the Absolute prior to evaporation of the alcohol.

This is the finished product after evaporation of the alcohol, the Absolute:

It is less fragrant than the concrete, but it gets you wrecked and it is smooth as hell to hit. The texture is like sticky silly putty. Pull quick and she snaps. Non-Newtonian awesomeness.

jw do you mean concrete? or concentrate? Wtf is concrete in relation to cannabis

I would try it, but I'm in California, so they only have 75.5%.

Is 350PSI safe with the Tamisium? Sounds dangerous.

I got shafted by Airgas again yesterday, but was assured (and woken up) at 7am that it would be here soon. Last night we did use the King butane and cleaned it. Why do you advise against using the N-Butane first?

I warn against using the pure N-butane first because it is so expensive, and you are likely to loose some. I was just trying to save you some money while you work through the initial experimentation.

Plus, I would wait for the device they are going to release that will recover %100 of the gas %100 of the time.

There is no reason other than that.

The rubbing alcohol is fine too. I didn't know Everclear was not legal everywhere. I'm not a drinker though.

I don't know if the 350 PSI was safe. Probably not. I didn't intentionally go that high, but it did. It may have been higher. It wasn't caused by adding air pressure, which I have done, but by overheating a charged butane tank in a hot water bath. I wanted to get it to around 200, but once the tank heated up, the pressure shot up faster than I anticipated. It buried the needle on the pressure gauge that comes with the unit, so I only know that it was higher than 300PSI.

Lower pressures and lower temps throughout the process has generally given me my best products. But, I'm new to this aspect of the game and I have a ton of learning to do.

You guys are making excellent posts. And I see yall got jump in here too. Respects Jump. If I had more time I would try and help but right now that's the one thing im lacking as of lately. MT u got good questions and I love that u know the right way to ask them.

Good luck to all of you.

Oh and just to let yall know, 99% isopropyl alcohol always leaves a nasty taste behind in my humble opinion. Grain alcohol does not. I dont know why, it just is. Acetone has been one of my favorite concrete makers. Good taste little to no residue. Has to be pure acetone tho. There is a thread on the farm if yall are interested. But of course not many are because hardly anyone thinks acetone is safe for making extracts.

I think that's if you use it as a co-solvent during primary extraction, not if you only use it as a transport solvent in the Tamisium. I may be wrong though.

Interesting. Im going to sit back and learn. Go back and read the thread one more time. Thank you for the quick reply.

Respects dextr0.
Concrete is a hydrophobic component, extracted with an organic non-polar solvent.
The extract was extracted by a hydrophilic polar acetone can not be called concrete.

I always suspected that the high selectivity of butane is due to its low temperature during extraction.
So, extraction with butane at room temperature is behaving the same way as polar ISO and EtOH,
and drives to Quick Wash in Butane like QWISO and QWEtOH.
Amazingly a lot of wax fell in your experience. You're freezing solution?

No, I did not place the solution in the freezer at any time. Everything was done at room temperature.

I'm confused by what you are saying about butane behaving like a polar solvent. Could you explain a little more. I have a good basic understanding of chemistry, but it has been almost a decade since I've spent time working in a lab, or taking chemistry classes.

I'm thinking about going back to campus to audit those courses I took years ago. If I don't regularly use something, I tend to forget a great deal about it.

With regards to the use of a polar solvent.... What is the proper term for the raw product. If I ran ISO or ETOH, through a packed chamber, and then evaporated off the alcohol, what it left if it isn't a Concrete?

Thank you all for the input.

Definitely it is not a Concrete. According to definition concrete is getting from extraction with non-polar organic solvent.
All evaporated extracts can be called Oleoresin, and to extracts of ethanol use the term Tincture.
Please read the dicussion about the terminology http://www.uk420.com/boards/index.php?showtopic=218091&st=15

Talking about the similarities of butane with polar solvents, I was referring to the duration of pure-phase extraction prior to the lipophilic contamination.
In my experiments with butane at atmospheric pressure when its temperature below the boiling point -0,5 ° C (32 ° F), pollution is not started within two hours.

Thank you for the link and the input. I have much to learn, but I am getting very happy with some of the final products.

Ok so last night and tonight l decided to turn my concrete into an absolute, if l can call it concrete, it's in shatter form at room temp, but l ran it from dry trim instead of fresh, so is it an oleresin or however its said?? Anyways!! Back to the BHO BHC chunk that im dissolving into this beautiful everclear

The everclear BHO mixture became very cloudy with white, waxy particles just liked you guys showed said. Then l froze it for 24 hours just for a lil extra. Well it started to suspend like a cloud and some sank a little, note this was very good, clean tasting BHO in shatter form at room temp. So l guess there are some waxes or something else left in there...

So l take the glass out tonight, 24 hours later and filter it through a brown coffe filter l had at the house. Unbelievable the wax or whatever it ended up filtering out.

So l just warm water bathed it really low and slow like l do my oil without the flame purge of course haha and scraped it up

lt is still shatter, maybe a LITTLE harder not much at all. But it is a little darker in color, still golden still beautiful. lt hits smoother like this in the absolute form or whatever, but it does take away that lemon zest it had before and l really do enjoy that taste and flavor. l guess that is what the waxy shit is l don't know, have no idea. Still debating if it's worth the extra work...

Heres some pics of the concrete and absolute side by side and some solo. Note the absolute is free from all the bubbles and looks like glass

Cool

That shit looks tasty, either way

Congratulations on your first Absolute Amber!

Hi ya'll!

Redisolving oleoresins and concretes into ethanol and freezing to ~about 0F, causes the waxes to coagulate, so that they can be simply filtered off.

There are ways to clean it up further, and I will post a thread on after the fact cleaning of extractions that outline the above procedure and one more.

Is there a method like this for cleaning the waxes out of high grade water hash from bubble bags?

The only technique that I am aware of, is Full Melt Clear Dome bubble hash, made by carefull processing and pulls from the 90/73 micron bag.

I have extracted the oil from bubble using alcohol and then clarified that.

If anyone is aware of any others, I'm all ears too!
