THC degredation

This image is of highly refined D9 THC which was out of vacuum long enough to photograph and harvest into this dish. I placed it in my small vac chamber to store it and the trapped air bubbles emerged as usual but it was cold enough not to pop several. One large one had emerged when I took it out of vacuum to dab the first time and I placed it back into the chamber and got stoned a bit and went for a walk. I just now grabbed another dab and noticed that the large air pocket had burst since before I walked to coffee.

Right where that large bubble was is a ring of red now! Lolz this stuff is sensitive to air. The upper right corner of the green edge of the silicon mat is in the center of where that bubble of air was. The rose color ring is dark enough to cast a shadow although faint.

I have a bell chamber and will purge all bubbles from now on. That chamber will pull down to pump blank off vacuum and stays pretty low after shut down. I do not envy commercial operators who are trying to keep this stuff clear - it is tough.

The correct solution is obviously to convince the public that they look good in pink :stuck_out_tongue:


Convincing the public of a fashion statement can really backfire. My proof is Spandex.

I think a cool trade name for the stuff like “Cherry Oil” for clear that “is allowed to age” into a “relaxing natural cherry :cherries: flavor” would be the marketing way to handle this. Code for pure that oxidized lolz :laughing: but on the other hand I swear that just a hint of red seems a little more fun to me. Not so stoney and just a nudge more chuckles.

I better log now. My oil is turning red and needs vaped and the Spandex is done in the dryer.


Outstanding clarity my friend. Distillation post-processing? I always notice red oxidation when even yellow tinted distillate sits in a jar. However, I ran some distillate through a C18 column once and the clear stuff had a more purple-ish pink oxidation color days later, like you showed in the other thread.

Maybe we should just store it under nitrous oxide? That would probably help, could improve the giggle effect too…

Update to the thread here. At this moment I have zero explanation that does not otherwise qualify as a “hunch”. All I have is the observation atm.

Above in the OP I showed the red “degredation” and concluded it was the exposure to atmosphere that had done this. I have in fact seen uncountable examples here of clear going to red which slows considerably under vacuum but always does seem to emerge because I release vacuum to grab a dab.

My conclusion is now … in doubt… hehe. I have shared that this month I did multiple change ups including a no terp boil of compound, an extended UVB exposure under deep vacuum, and fine ground pure 100% carbon powder (made from only American hardwood trees, over American flames, lit by American matches) during the final boil as well. The number of other details these items then impact generally equate to “lower temps and pressures” because of doing those things.

So those are the differences between my “pure” (ya right) compound above and my pure compound I just snapped a picture of under the exact same light on the bench as the first picture. I needed a white background because the first trace of red now is so faint it could not be seen otherwise. I also had to score the surface to get the camera to focus where it is. Just a trace surface film of pink is near the top of that little cut in compound in the center of the frame and between the petri glass edge. It is VERY faint but looks like a thin line going up from that small cut.

Yet this dab now has been in and out of the chamber now for at least four days and just now is only beginning under high scrutiny to show a trace of pink that only trained eyes can spot??? As I said, hunches are hunches but there is only a single conclusion I can make atm with the observations I have that can explain this. I have been sacrificing my time in research of this medicine :crazy_face: for years and it just seems like some ideas are lining up.

What are your thoughts on why it is now taking days on this batch to show up the red as just a trace at best whereas in the photo above and prior experience this would be detected in hours and from a short distance by me (photo above)? To be fair I have multiple other photos to work with in this including unexplained outgassing at steps where normally there is none but this too lines up with a “hunch” that seems sort of impossible lol.

So I am replying as a way to introduce more data.


Generally, red is a symptomatic indicator of the presence of an acidic compound (pH<7), Purple is same for base compound (pH>7).

Could be a reaction with something in your shop air as well.
