Nice job Jump.

Buds matter in butane.


Extraction tea-pot, filter, butane oil-cake, butane evap.


Concrete








Flakes in ethanol, filtration, slime.


After filtration the solution was shared half-and-half. 30/2= 15 ml.
First half goes to final distillation and collecting.







Second half goes to freeze -20°C for four hours before filtration, distillation and collecting.


With or without "winterization" in my opinion they are the same. On the last picture a piece from previous session added (left).



Hey ICMaggers, to me it is amazing, why no one will repeat this? Go ahead, its easy!

Beautiful jump! I will try soon.

What would be the best way to store a bunch of amber long term (many months or even years)? Would you recommend keeping it in ethanol solution or leaving it in the extracted absolute form?

Hey guys,

Some good stuff in this thread. I love the way the absolute product looks.

I have one quick question. Do you think there is any significant difference between using ethanol for the "secondary extraction" and filtering verse using isopropyl alcohol?

I did my BHO tube style extraction directly into a container with a small amount of Iso covering the bottom to help with purging of the butane at ~ 85deg F (29) for about an hour. I then filter the iso through activated charcoal and a coffee filter. This liquid then is evaporated at 85F for 24 hours until all the iso is gone.

Now i am thinking of doing dissolution into ethanol and freezing for 24hrs then doing another filter and evap.

But if we think the iso works just as well then ill stick with that. It is much cheaper then 180 proof ethanol.

Slimm,
ethanol solution stored in the dark place at room temperature had changed its color from light yellow to dark amber in 5 months.
Within 4 months several ethanol solutions in the freezer at -20°C have not changed in appearance.
I have never stored ambers for so long, they always go to heaven young. I believe that in the freezer they can be kept forever.

gunnaknow, I've got it.

organicgreen0,
I have never used ISO and never learned its properties.
Note that the second solvent is required in very small quantities, it can soften the financial shock of the price of ethanol.

ISO should work fine for this. Most waxes are poorly dissolved in alcohols in general. ISO generally has to be heated to high temperatures to dissolve much wax.

Great thread jump. I plan to sit down with a big bag of bud and work until I reproduce your results.

How is Honey oil, which behaves as a thick liquid at room temp, different from the solid-at-room-temp absolutes being pictured in this thread? What gives the oil a malleable consistency? Is this due to water left behind from the alcohol?

If one wanted to create a decarboxilated absolute, at what point in the process would this be done? I assume after the etoh wash and filter? Also how would one heat the solution so a minimum of the terpenes and cannabinoids are lost in the process.

Gunna,

Here's a qoute from your post in the thread referenced above.

Butaflor is a registered name (P Robertet & Cie) given to a series of highly concentrated perfume materials produced by extraction with butane at subnormal temperatures. The solvent is recovered be evaporation at room temperature (boiling point of butane is -0°.50C). The low extraction temperature and the selected solvent result in a pale-coloured, almost wax free and terpenless product. The method is particularily useful and advantageous when applied to very delicate or heat sensitive botanical materials, e.g. lilac flowers. jasmin, rose, lily of the valley (muguet), orange flowers etc. Certain staple materials are also treated in this method, e.g. ginger rhizomes. It should be kept in mind that not all Butaflors are completely alcohol solvent.

My concern is that with low extraction temps less terpenes are extracted - terpenes are essential to the effect of the product. Is another wash of the source material needed, with another solvent, to pick up the terpenes?

Waxes, fats, oils work as a softener. Water evaporates together with ethanol from azeotrope solution.

I suppose this would be done after final evaporating as an additional process.

they say this temperature is not safe to terpens, many of them fly away others oxidize into another forms,
vacuum would help to save virgin terpenes in evaporation under 50C (122F),
on the other hand in terms of THC content its better 20-30 minutes at 122C (252F).

It seems impossible to keep terpenes after decarboxylation, it requires the temperature much higher then many terpenes may withstand.

Great info and presentation.
I might try it in a near future
