QWEVER?

Ive only made oil a few times using ISO but recently caught hell from a friend for using it so thought I'd try everclear. Used an ounce of Alien OG bud in one and CBD OG trim in the other. Both trays were crystal clear (trim has green tint) but after a while the one on the hot plate (very low heat) turned milky white and the oil separated. I'm guessing the white is water it's picking up as it evaporates? I'm no chemist. IMG_2012.JPGIMG_2013.JPG

I did a relatively quick wash. Maybe 5 minutes. Solvent was in the freezer for a few days. Ive read that with ethanol to soak it 24 hours. Is that necessary? Seems like overkill. Just judging by whats in the tray is roughly the same amount ive netted with ISO.

If you were to pour the water off you'd get rid of the water solubles, none of which are good for you or get you high. I would cool it off first though if you do it, to make the resins less soluble. By drying the water off you're actually locking that stuff in there when you had a perfect opportunity to chuck it.

Uhhh no

Haven't you been told to stop giving advice especially in things youve never actually done..

Lol

Yup, the white is water and will go away with the water. Some from the atmosphere, some from the plant matter, and almost 5% in the azeotropic Everclear. Blowing a fan across a tray of ethanol on a humid day dramatically increases it, because EtOH is hygroscopic and hydrophylic.

We've found vacuum distillation at low temperatures to be the best solution, but adds equipment.

Here is the QWET process we use:https://skunkpharmresearch.com/qwet-extraction/

Your green is from too long a soak at too high a temperature, but isn't dark enough that it couldn't be bleached out in sunlight or strong UV. That will cost some potency, but not an excessive amount.

I vacuum purge at around 125F after the visible alcohol is gone. EtOh and cannabis essential oils blow incredibly large bubbles and takes forever to purge at lower temperatures.

After I scraped my pans i vacuum purged for several hours. The product from the bud ended up like a stiff sap and sugar leaf stuff got a little brittle like shatter. I noticed a much better flavor than ISO, even the green batch tasted good. ISO always had a chemical taste imo.

If it were a frozen extraction, which I believe it was, pouring off the water is a problem. All of the floating terpenes will be poured off with the water. If it was a warm extraction, it may be worth the sacrifice for taste reasons if you plan to just smoke it.

When it comes to QWET I do not like to use 190 everclear. I have done it plenty of times and have done plenty of side-by-side comparisons. No, 99% iso does not cause the same type of water problem, and yes, it is a problem. 1% compared to what you show in your picture, no big deal. 200 proof ethyl does not cause the water problem either.

In the event the buds were not thoroughly dried, there could still be a water problem with a frozen or room temp extraction.

The only use I have now for 190 or 192 proof grain alcohol is cleaning, winterizing, tinctures, and possibly making RSO since it goes into the rice cooker and will help evaporate the water. I won't use anything lower than 99% alcohol.

I've never seen any floating terpenes, and neither have you. The explanation is obvious, they are mixed with the rest of the resin. Please explain how the terps would separate from the resin and float to the surface. All you're doing by keeping the water layer in there is keeping all the sugar in there. How is that a good thing?

That's not how it works lol

There is no water layer floating above the alcohol


As the fluid dries/concentration rises....resin drops out

That is because I am familiar with essential oils and the methods of extracting those essential oils. I have done plenty of research on this. There are terpenes that are lighter than water and will float on the water. These terpenes cannot be seen by the naked eye. Sometimes, when the extraction is extremely clean, grouped terpenes can be seen, but they will not be visible in the milky water when doing an extraction with less than 99% alcohol.

As far as the science, that is irrelevant. I am speaking from experience. I have made the same mistakes in the past and learned the hard way. Now I know better and am simply sharing my knowledge. In the past I have done the same and simply removed the water, but, again, now I know better.

Yeah I know terps float on water. I also know that they don't spontaneously separate from the other organics which they are solvents for. If that actually happened there would be no need for steam distillation, now would there? You could just skim them off. You're just wrong dude, sorry.

True, but also not true.

When you get down to where it is just water on top of the oil, the alcohol has evaporated and what remains is the water from the alcohol. This is when doing a QWET extraction or any alcohol below 99%. I have done a QWET extraction many times, have you?

Your mind bogglingly dumb..
