Thanks for the replies.

I am just trying to get the product clean as possible of anything that will not nicely dissolve into my glycerin/propylene glycol mixture.

Yes, there may be some truth to that. However, butane extracts the cannabinoids effectively, which are terpenoids, so it should be able to extract terpenes effectively also. The typical materials used in making butaflors are fairly low in terpenes compared to cannabis. There aren't many plants that produce as much aroma as cannabis. Butane may extract less of the terpenes than ambient temperature non polar solvents but when the terpene content of the plant material is so high, a large amount will make it's way into the extract. You also have to take into account the fact that butane can be purged off at low temps and quickly, which allows the BHO to hold on to more of it's terpene content than oleoresin made with other solvents.

Terpenes may modulate the experience of the high to some degree but that doesn't necessarily mean that more of them will increase the effect. However, if you want to extract the maximum amount of terpenes then you could do a second extraction with an ambient temperature solvent. You'd also want to use fresh plant material, as many of the more volatile terpenes evaporate during drying. The first extraction on fresh plant material would need to be with butane because an ambient temperature solvent would need heat or a lengthy purge time, which would drive off the most volatile terpenes.

Ok, gave this a try last night, my tech varied in a couple of places, but the outcome I give 2 thumbs up Here is the rundown, I might break the camera out, if not for sure next time.

Took approx 2 gms of 2nd run BHO of which both were fairly dark and more opaque than 1st runs, and dissolved them in an amount on ISO that covered them by about double.

Took a glass poker and agitated them until they dissolved in solution which is clear at this point but has the tint of the starting product.

Took this and put it in the freezer for approx 3 hours. When I took it out, there was a white cloudy substance floating just below the surface (I took this to be separated waxes)

I then poured this through a coffee filer onto a pyrex plate and let evap at room temp (78 degrees) overnight.

Product I scraped was lighter than starting material and very clear. Very clean taste considering starting product and nice "up" non couchlock effect.

Looking forward to trying this with 1st run A+ material

This Maple_Leaf was not reversed in a whole. It had both active sexes and was yielded with both pollen and seeds.
34 fem seeds ML x SK, a little ML fem pollen and a piece of absolute amber extracted from separated ML flowers matter.

I had a couple of ambers like twins. I put one of them in flat-bottomed conical lab glass and placed in the oven for 20 minutes at 122C.
First amber melted into a puddle, five minutes later the whole puddle was covered with tiny bubbles, which in ten minutes gone.
I think that is carbon dioxide released during decarboxylation. I didn't pictured this now but before in "home-made charas".
Within the next 10 minutes to appear only rare microscopic bubbles.
I think extra time after bubbles gone was useless and harmful.
No bubbles, no decarboxylation, only oxydation.
Ex-twins to compare. The colour turns darker. Consistency changed from brittle amber for a thick sticky resin.

Absolute Decarboxylated is absolutely odorless.

Yeah I made some and it smoked with almost no flavor.

[jump117]

I use a flame of a lighter to soften and melt amber to operate with. As:
-to melt shards of amber together in one monolyth piece,
-to remaster shapes of a samples,
-to smooth sharp edges,
-to fix a sample in the position for taking the picture, side melt and stick like the thermo-fusible glue,
-to separate a part of an amber.

Amber can soften and melt without affecting its texture, after cooling it remains fragile.
Doing this I avoid the boiling that appears in a surface layer when overheated.
Sometimes it had happened as an accident.

Never before I correlated this to decarboxylation, neither analyzed consistency of accidentally overheated bubbled parts.
Now I observed the changes of the color and density of the amber after decarboxylation.
To check this observation a piece of amber was overheated from one end to the allocation of bubbles in the surface layer.
After the sample cooled to room temperature, I examined it with a microscope by manipulating the two needles.
Fragility was not restored to the overheated region after cooling.
This area turns to sticky thick resin with visible border between two phases (see macro).
It sticks to everything. Gossamer from the resin is living together with the movement of air,
while the spider from molten amber turns into a glass thread and breaks into pieces.

Newborn THC is watching you with its eyes of carbon dioxyde bubbles.





My assumption based on observation is that

-THCA may crystalize while THC may not.
-Presence of THC softens the stoned THCA resin.
-Extracts made from cured floral material with a high content of viscous THC are runny and can not be glassy.
-The glass amber can be extracted only from flowers with a high content of THCA and low or none THC.

Welcome to criticize or to confirm.

If this was a BHO thread everyone would say it's the terpene bubbles, and there's no telling them otherwise.
Cannabinoid acid extract made starting with the least polar solvent possible, then freed of most everything else by extracting into NaOH and so on, is a perfectly non-sticky dry powder. (Edit: GW Pharma says their 98% THCA melts at 70°C)
Keep up the good work!

it may not be terpene bubbles, but they sure aint butane bubbles, thats what people really go on about often and are full of shit about.i dont know for sure they are terpene bubbles, but i DO KNOW that if you evaporate most of the bubbles out of a plate of butane extract, you lose a lot of the flavor component. so either some or all the bubbles are terpenes offgassing, or they offgass as a vapor with no bubble formation. that seems unlikely.

I've gotten solid shatter off buds that were cured for 12+ months many times.
