I.e. ” Sir-dabs.. I'm making oil and I want shatter... like, hard shatter, I can't seem to get a rock hard finish”
^ That is a paraphrased version of various pm's I receive, at least once, twice a month.
My” answer” only applies to the non-polar properties of a butane extraction.
Polar Solvents are a different ball-park
Is this what you are referring to?..when I say/repeat...
” With material being fresh and not cured, THCa is still in it's carboxyl group, producing a resin referred to as a Concrete
Again referring to the properties of butane extractions...
Older material, Particularly the Top buds of main colas that have been cured and aged perfectly for smoking.
In my experience..extracting oil from these buds always produces a more sappy, softer supple resin that is more susceptible to nucleation.
Commonly referred to as an
Oleoresin
In relation to polar solvents that same principle does not apply
With chilled Iso extractions, it produces hard brittle resin regardless of the carboxyl group and it's current state or age.
I've performed way over 200 or so butane extractions, and the theory of the carboxyl group seems to apply consistently.
Fresh material, always produces rock hard shatter.
Young material, can vary, from rock hard to a supple sap to auto-nucleation.
Old cured top buds that are in my Smoke Jars...
Always produces sap or nucleates rapidly.
I'm not a scientist nor a chemist, but I do take what others have taught me (including QK) very seriously and simply apply these teachings to my extractions.
Qk.
I don't remember brotha..
You've done a handful of butane extractions right?
In closing..
Polar solvents; that carboxyl group does not seem to matter.
Non polars, the carboxyl group plays a big role in the finally consistency.
