Interested in finding out the correct process needed/used to create the kind of golden-colored, honey like oil used in medical mariguana vape pens.

These are special pens that accept this very thick, slow moving oil. They are not the pens sold in vape stores.

Can this oil be derived using the so-called RSO technique?

I start with organic, pesticide free (tested w/COA) raw material, homogenize and dry, then rough extract a concrete oleoresin via supercritical carbon dioxide extraction. I then employ a variety of methods commonly employed in legacy edible oils industries to improve color, remove odor, remove solids and remove oxidizing compounds. The end result of this is the honey colored liquid you're referring to, it's fairly high cannabinoid by volume, my most recent batch having come back from the Wiped Film at 989mg/g cannabinoid total.

I then take purified terpenes and blend them back in at a specific volume dilution, leaving you with only terpenes and cannabis oil, housed in a stainless steel and borosilicate glass housing. I am moving to ceramic cell cartridges as they handle the solid load better and reflect taste better, but high quality cotton wick carts can still be had via Itsuwa.

Just curious if you are using cannabis derived terpenes?

Well, you are probably doing it using similar advanced techniques as the big boys. Not something I can do at home.

Can the more simplified extraction methods of using cold grain alcohol and a rice cooker or (water) distiller produce an oil that can be vaped is what I'm trying to find out.

Or is there a modification to this process that will get me there?

No. It's a controversial subject, but I don't.

Any properly winterized oil that has been decarbed can be effective, that's still more than most of the "big boys" do. Finding a cost effective atomizer will be difficult for small volume though. I use a Saionara from Humboldt Vape Tech that has been fitted with a ceramic "donut" for consuming my own product personally, paired with a Smok Alien battery mod. The reason you want to clean it up as much as possible is largely related to how much residue it leaves behind, and I'm sure how you can see in a 0.5gr or 1gr cartridge that can be problematic, but a larger unit like the one I use suffers less impact from the solid load.

Ok, so please excuse my lack of knowledge on this subject but I have some basic questions.

The product to be processed... Are you using fresh material just cut down or are you drying and curing as if you were going to smoke with a pipe? In other words, how to you prep the material... in simplest terms?

What parts of the plant gets used?

When you say "winterization" are you referring to the cold extraction process using, for instance, dry ice and one of those shaker siev bags?

Can it also be done using dry ice, to chill the material and grain alcohol, then strain and filter, then use a distiller to remove the alcohol?

I dry to reduce the water content of the raw material prior to extraction in the same way you would for smoking out of a pipe, being mindful of temperature and humidity that will reduce water content but not strip it of the aromatic compounds I'm looking to preserve, if I am looking to preserve them through that process.

The reason for this is that though people don't think about it, the water present during extraction will act as a co-solvent, pulling undesirable material along for the ride (water solubles and chlorophyll which is miscible in water). Those compounds are comparatively more difficult to remove later and lend to the degradation and negative reception of the product.

In my professional process I utilize any of the plant that has cannabinoid material on it. We also prepare the raw material after grinding by sifting and removing inactive material such as stems. I have a limited vessel volume so I need to pack as much of the target analyte into it as I can. Stems are wasted space and add more inactive content I'll have to remove later.

When I refer to winterization I'm referring to the same thing you do for other oil types to reduce solid content, sometimes in the presence of a solvent, sometimes not. Winterizing diesel fuel allows you to operate a diesel engine without a warming pan in colder climates by reducing the compounds that solidify at cold temperatures. Our industry has bastardized it and uses it to refer to dewaxing, degumming etc, but typically you dissolve in Ethanol, filter out solids by reducing temperature (which can be achieved via dry ice).

You only "winterize" if you process with butune or another solvent first. If you just use alcohol, then it is called QWET - Quick Wash Ethanol. Start here:

You would be quite surprised by what still comes out after QWET. Maybe. I don't know what your experience level is. Most people are surprised though, which is why cold is the name of the game with EToH extraction these days.
