If my old IG account hadn’t been deleted, I could’ve shown you a post about 3-4 years ago B.C. (before crc 
) where I was doing this while trying to learn Pyrex tek. I used to play with butane and Büchner funnels a lot so I know I was seeing it back then just didn’t understand it at the time

Cmon your not hoping on the Murphy bandwagon saying all of us that are having this problem are just incompetent and cant run a cls properly? All I know is our sop was the same for years before this problem came up. Now we have to do everything possible to prevent thca from crashing out. Before it was difficult to make crash out which is why most people had sugar for years and there were only a few of us making nice diamonds.

Never said you or anyone was incompetent. I’m just saying if you off gas, it’s gonna cool things down and reduce solubility causing the thca to crash out. Just speaking from my experience that’s all

You are missing the issue pretty badly, I’ve got to say. Buchner funneling butane is not something I’d hold up as proof. More something I’d bring up in group therapy.
While one sounds like the the other, I’m telling you, as loudly as I can, that I couldn’t leave a jar of 300 ml of butane for 20 minutes and have it crash to finished, even 1 year ago. I really truly doubt you could either. I also use to open blast, and I never saw anything resembling this. Lot of cold reduction of solvent in those days as well.
I appreciate that you haven’t dealt with this issue, but there’s a lot of big names here, some of whoms coattails I still ride in my own work, and they’re all loudly saying they haven’t changed SOP, biomass, or how they leave butane to offgas. I’m here to add my voice to that pile. We ain’t changed shit.
I don’t deny butane doesn’t like to stay capped in a mason jar, but I know the difference between a jar that leaked and went to straight sugar, and a jar I capped and watched sugar out despite not leaking in the slightest.

Wholeheartedly agree with this sentiment.
Well I shared what I know and what I’ve seen. Sorry it’s happening to others hopefully the points I discussed will help in figuring it out

I will have a 5000 gram pour completely crash out in 30 minutes in a massive sealed miner. I think I’m dealing with the quick crash so bad when others are not because I’m using Cortland gas. Going to try some diversified stuff to see if I can stop it as it’s annoying af. Down to do the test though. I’ll give you a Cortland tank if you want to try it yourself and see if you see it.

I’ve been using gas from @GasLogix-Adam for the last 6 months and have had zero issues. Pretty sure gas logix distributes for cortland

@Waxplug1 , I have performed numerous extraction and purification processes with BHO systems in the past, although that was apparently before these issues began cropping up… first on the West coast, and spreading over the following year across to the East coast of the US. I am not a manufacturer of cannabinoid products, but I have witnessed these phenomena with clients and in facilities with whom I am affiliated and working… some first-hand; others remotely. Does that answer your question? I am curious, why do you ask?

I wanted to know if you’ve witnessed these yourself. I’ve only seen Medusa before but not the fast crash. I’m curious as to what the alumina is fixing in regards to fast crash. Cold crashing thca is something we do to produce thca isolate so I find it hard to believe the alumina will prevent this from happening

I’m down to come check this out for myself if it’s still happening

Ah, well then the answer is YES, for sure!
I have based my working theory on all of the evidence I have seen presented by others and first-hand. I mentally analyzed all the data to come up with a list of properties and behaviors, then imagined a hypothetical process by which every anecdote could occur, and under which none were being violated or ignored.
The concept of the specific type of impurity that could accomplish all this came to me as folks like @Dred_pirate, @johnbigoilco and @Dukejohnson were describing the properties of their “petrified” THCa stones… like the specific ways in which they melt & decarboxylate differently from normal THCa crystals. These properties made me think of an old experimental procedure I did with Winterized & unwinterized crude resins in hexane and aqueous 29+% ammonium hydroxide. The ammonium*THCa product that formed (see my profile avatar photo) had VERY similar properties to those these oddly perfect, yet differently shaped, eventually medusa-petrified ‘polymorphs’ of THCa crystals were demonstrating. Soon, it came to light that small organic amines have historically been used in the petroleum industry to “sweeten” or de-acidify the LPG and other petroleum distillates. Knowing the potential of the various secondary & tertiary amines to form and precipitate Lewis acid conjugate “salts” with THCa in/from solutions, all the data finally clicked together in my head…
So I wrote it all out in Post # 337 (and reworded in # 420) of the “It’s not iSoBuTaNe” thread… along with some remediation tips in Post# 424.

I wish I could fast crash like you guys honestly. I have to centrifuge to produce my thca isolate

You CAN fast crash like they do, but we are all certain you DON’T actually WANT to crash in the uncontrolled and deleterious manner they do. We promise! That said, it IS also possible to fast-crash by means OTHER than this bastardly impurity, and with much more control over the results!

I still don’t believe it’s an impurity causing the fast crash. Now if it crashes while the solution is hot in the pot or in the surge tank like @Dred_pirate said then I would believe it but I just don’t see it nor have I seen it with other labs I’ve been to. Now if it crashes because it’s off gassing that’s just the way things work, it cold crashes. 10-20min of off gassing like the fast crash is reported is definitely enough cold to cause it to crash out
I have a couple jars of the precipitate that I’ve saved, too

I used to leave pyrexes open to atmosphere for weeks with no crystallization. Now it happens instantly.

6 minutes out of the extractor in a 65F room. No acidic clay.
Pyrex very cold to touch, something (an amine?) causing very rapid evaporation.
Pyrex diamonds the week before. Same SOP, different gas.
New tank of gas distilled, but not 13x molsieve filtered prior to distillation.

Leaving it open like that with so much surface area can cause moisture to build up and the moisture will cause the thca to drop out faster. That’s why too much moisture in the crc causes clogs. It forces some thca to crash out and blind the crc
