Hey dope_roor! Thanks for sharing and Sorry that you remove pictures, where can I see that porous sample again?

re-edited the photos back in!

quite a strange phenomenon, when the oil becomes "swiss cheese"

I have always freeze loaded extractor and the butane can before extraction
In order to minimize the rapid evaporation of butane at the beginning of the process
And avoid accidental ejection of the staff and evaporation losses.

In the process of evaporation, collection and give amber a convenient form
It is melted several times at about 70°C (158°F) and returns to brittle at room temp.
imo its hard brittle texture indicates a high content of THСA, which may crystallize.
That means decarboxylation didn’t happened.

I regularly observe the change in consistency after decarboxylation.
When smoking at home, I use digital soldering iron with an open ceramic heater.
Sometimes happens that a shard of brittle amber does not have time to evaporate,
It melts, wraps around the heater and drips on the bottom glass plate.
Fragility never returns to this drop,
It is sticky forever because of the decrease in the THСA/THC ratio
after decarboxylation from THCA to THC, which may not crystallize.

I do not know whether decarboxylation is reversible or not
and whether this process occurs during crystallization, which you describe.
Many times I read the description of crystallization by the type of honey sugaring,
waxing, formation of spongy porous surface, I never saw such changes, is it autobuddering?
Is it what you asked?
Crystallization or offgasing of residual butane and/or/? terpens, sorry I don't know.

My own experience parallels Jumps and I don't know for sure what is going on either.

As he notes, THCA is much stiffer than THC decarboxylized and it is a much lighter color.

I have never experienced the Swiss cheeze phenomenom, so I will play around and see what happens. The auto buddering that I have observed, has looked different, but was not left undisturbed to form Swiss cheese.

My tongue in cheek thoughts regarding the phenomenom, is that decarboxylation involves giving up C02, which is most likely what makes the bubbles.

My reading research describes such a autobuddering phenomenom, if the oil is placed in a food dessicator. I will start expermenting there.

I cannot remember if this has been discussed, but it has been on my mind as of late.

Do the absolutes that you produce possess as pungent of a flavor profile as the concrete oleoresin (BHO)?

I am curious if any volatile terpenes are lost at all in the process. I am not theorizing towards one way or the other, but am quite curious to know the subjective opinions of those that have performed this process.

All of the alcohol washes I have performed have not been nearly as flavorful as butane extractions. The flavors are often described as hashy or some other generic descriptor, whereas butane extracts always taste more or less exactly as the flowers smelled.

If only photos could convey aroma/fragrance...this one looks delicious.

Hey Trichgnomes,

The strongest smell exudes fresh butane extract,
even without any additional impact the intensity of the smell quickly weakened,
or the sense of smell quickly adapts to it, not sure.

Dissolution of the primary extract in ethanol does not alter the picture of smells.
But the evaporation of ethanol on a steam bath is clearly weakens the richness of the bouquet.
When evaporation occurs without heating, the extract is a more flavorful, but with hints of the smell of ethanol.
Note that ethanol does not smell as disgusting as isopropyl.

I'm talking about the loss of a very volatile and delicate flavor component, akin to those that ooze fresh flowers.
Resinous aroma of hashish is preserved and smoking can not be called tasteless or flat.

I can not boast of a remarkable sense of smell and in my opinion, the aromas of smoke ambers of different species differ little,
some of the varietal nuances, such as Hazes, easily distinguished after the evaporation of heated.

They say vacuum evaporation will provide complete smell preservation,
although for the purging of solid shatter amber still have to melt to ensure the mobility of bubbles in its thickness.

Amber in the solid state does not smell.

The last time I tried making AA, I tried soaking the herb in butane instead of running butane through the herb.. I wound up losing pretty much all the butane b/c it evaporated by the time I tried pouring it out.. Any recommendations for this? I see you spray the butane into a small hole into the thermos. Doesnt pressure build up like crazy? Then how do you keep the pressure in, which might keep the butane from evaping so quickly?
-Since that time that the butane evaped before I could pour it out (and I did put the bowl that the weed and butane in the freezer while it was soaking, and had pre cooled the butane, not the bowl..) but any ways, since then, I have resorted to the whipping method for budder and earwax. Have that down to perfection, but still just a tiny bit less potent and clean than the amber..

-The chip is a beautiful thing, along w/ all your other amber.
I hope I wind up getting it!

It may seem that pressure is high, but in fact, it's not that powerful, overall. I would put 3 1/2 cans into a 2 liter coke bottle and had no problems for years. Same thing as the thermos, practically.

Butane boils at ~30F. If you keep the material and equipment below that temperature, the butane stays liquid.........

thanks guys between the 2 of you I got both my questions answered.. Ill have to do it next time its snowing or something and see what happens.. I was going to go and buy a thermos but I might have to try the 2 liter bottle thing that sounds pretty easy..
