yes, thats correct. i freeze all material before hand... making sure the iso is as cold as the freezer will go
and the material, i freeze for 2wks or more before hand... i have found some supporting evidence and can link if absolutely necessary that cold temperatures in itself, Breaks down chlorophyll. This is why the extended duration for the material in the freezer... what people consider a "quick wash" by pouring into a jar and shaking for 10-30seconds... is insane. By the time they pour their iso into their jar, Im already done.


i really do invite people to take this challenge, see the results for yourself.
im laughing at the people sitting there saying how can you claim one is more potent than the other. well quite simple, have you tried it?(and no i dont mean this batch, a head to head comparison of iso vs butane) because I have.


i will make a video if needed to outline my method.

Again tops for home extractions are iso with dry ice, dripped thru a carbon filter. Ive never seen anything that quality from a home extract

Solvent properties are temperature-dependent, yes ... but not polarity - it's a basic feature of the solvent, like molecular weight.

I have not yet tried butane at room temp ... but I will one day. My best analogous extractions have been with pentane and hexanes ... very close to butane in re polarity and solvency.
The greenest oils I have seen use aggressive solvents like acetone, dichloromethane and the alcohols. My hextracts are gold-yellow in dilution and brown when freed of solvent ... and they are tasty imho. I've never done a quick-wash myself, except as a "control" next to an exhaustive hextraction to determine efficiency.
Mind you; I am not seeking to argue. e.g. I would never argue with Oakley's results. But I do have experience with a wide array of solvents ... even some semi-exotic cannabis extraction experience. cn

I love the golden flakey dust i get to scrape off my okief after sitting for a few days after doing a couple runs. shit is so tasty!IMG_0211.jpg

"It is not commonly appreciated that retention indices are temperature dependent. It is even less common to express this fact in more practical terms by saying that polarity is temperature dependent. Although the meaning of both statements is identical, we believe the second to be particularly relevant, since the majority of practical gas chromatographers tends to handle polarity as an invariable characteristic of a stationary phase."

i think both the solute and solvent in the case of cannaextracts are temp dependent.

i most definitely agree they are temperature dependent.

If a solvent will change phase from temperature changes, is it not possible to say temperature can drastically affect solvent properties ie liquid tane vs gas tane.

Oho ... but gas chromatography is a different animal entirely. It does not really treat of the liquid phase of solvents. Also, since the temperature of the retained/fractionated vapor entity and the stationary phase's liquid component (typically a PEG wax) are both being changed, there is no real way to assign how much of what is a polarity effect. it's an equation in at least two variables.
Of course this is all tangential. I could be off in my count of angels on the pinhead. Solvent properties taken as a collective are definitely temperature-dependent ... hotter solvents are invariably "hotter" in their behavior. cn

Of course. But I am abiding by a convention that only calls liquids "solvents". Supercritical extraction is a special case ... supercrit practitioners refer to the extractant phase as a "fluid" since it is neither liquid nor gas, but mixes properties of both. cn
