Who do you use now? Solvent direct?
Absolutely not. they are double the price of most suppliers i have talked to and charge a fat premium for delivery.

If anyone is interested in trying out the gas we carry at Xtractor Depot, we will provide a money back guarantee for any new customers if you have any issues. We changed our source for gas and haven’t had the issue come up for our customers. We also provide a 3rd party coa on every lot and clean the tanks like SD. Shoot me a DM if you’re interested!

Interesting, could you elaborate on changing your source? If anyone fully cracks what’s going on they get my business that’s for sure.

So you are not gonna say who you supply though?

Shipping is always the issue. I buy 1 to 2 tanks at a time right now and dont like paying for pallets on fright trucks.
Do you have distribution in Seattle?

We used to work with HPG but with our purchase volume, we found a new distributor for Diversified to work with. I think we tried to get you some gas down in San Diego right? The offer is still available if you’re interested.
What’s your shipping zip code? Let me see what it would cost to get it out there to you. Since we’re both on the west coast, it might be reasonable.
Have you guys heard the myth of the origin of crystalline glycerin?
https://pubs.acs.org/doi/pdf/10.1021/ja01654a014#
"…Glycerin is an important compound used as lubricant, food additive, and various industrial ingredients. However, no one has ever been able to crystallize it, leading to the belief that the solid state of glycerin does not exist.” (Figure 2.15)
But one day, a barrel-full of glycerin on a British cargo ship was found completely crystallized. When the news spread and the laboratories everywhere rushed to ask for a sample as seed crystal, something strange happened. Shortly after the discovery, the glycerins in factories and laboratories around the world began to crystallize all together even without seed crystals. That puzzled the chemists in all fields, because nothing had been changed in both production and storage conditions. A speculation that a seed crystal might have gotten in from someone’s clothing or skin was unlikely because carefully controlled experiments showed the same result. Today, glycerin can be crystallized easily by anyone by simply cooling it to seventeen degrees Celsius…… "
Well, this is the legend which has become famous recently and has even been on a cartoon. Professor Makoto Kikuchi of Osaka University in Japan has done an investigation on this case, and he arrived at an article published on the Journal of American Chemical Society in 1923. The article said:
“After the seed crystals had arrived it was found that crystallization practically always occurred when amounts of 100 g. of any laboratory sample were slowly warmed over a period of a day, after cooling to liquid-air temperatures. This occurred even when great precautions were taken to exclude the presence of seeds. However, it was found readily possible, by temperature manipulation alone, to produce crystalline or supercooled glycerol at will.” J. Am. Chem. Soc. 1923, 45, 93.

Does he have Medusa free gas?
Nobody has a consistent supply of clean gas.

I just read that cannabis can produce trace amounts of hydrogen peroxide.
So, if it was the hydrogen peroxide … wouldn’t this have happened before with the people who semi-mill/partially grind their material before they made diamonds in the past?
Especially live resin runs if the whole plant is un-cured and fresh frozen with the off chances of the cannabis still being in “defensive mode” with the resin glands going full force “defense mode” they’d be producing peak amounts of hydrogen peroxide in the glands would they not?

Then again if the gas is contaminated with H202 then I wonder if there’s a reaction/interaction between the plants H202 and the H202 in the gas…

Did you ran derivatized samples in the GC ? 
The way this product crashed looks like it forms a very nice “gel” in ethanol.
All these observations actually reminds me of some weird CBD isolate I received for analysis some years ago, in early Swiss CBD times. It would dissolve only in warm solvent (EtOH, MeOH, or Ac), but mostly recrash in weird flocs as solvent cooled down to room temp. Analysis suggestedd it was mostly made of CBD. I never saw such product again since then. I believe I still have this stuff…
@MagisterChemist Suggested “co-crystals”, which makes sense here. This looks like a sol-gel process, where THCa would polymerize with something else. This polymerizing agent would come either from the extract, or from the solvent, and become active once a sufficient degree of purity (regarding others waxes, pigments, oils…) as been reached in the solvent.
If this were the case the Medusa stones would have been an issue from the beginning

Listened to @murphymurri on her ig and she said she doesn’t have Medusa issues because she knows her solvent ratios and she cleans her collection pot with soap and water and water again after every run.
She says people are having Medusa issues because they aren’t consistent and don’t actually know their solvent ratios and don’t soap and water their collection pots. She does not believe it is an impurity.
This is my understanding of what she said. Maybe she can clarify some points if I’m wrong.
Opinions on this perspective?
Mine is that people did the same thing forever and that includes probably not using temp and pressure to guesstimate solvent ratio on each run and not washing with soap and water and their stuff was not having chalking issues forever and then issues started happening with the only different variable being a new tank of solvent.
@Dukejohnson says he runs at 2 different places and one has an older tank of solvent and he doesn’t have the issue. Not exactly 100% scientific but it says Alain especially when it’s coming form a knowledgeable and talented person like him.

I know exactly how many liters of solvent I sent per run. On the same exact machine. I operated it exactly the same and didn’t have the issue before all of this showed up. I even got butane to nucleate exactly the way I wanted, at colder temperatures than I do now.
This is in a 55°~ room.
This was done in a 79° oven under almost the same parameters.
Now, is this person able to get reputable sized facets in butane? I mean, something to brag about. Not micro grains. Like, diamonds that would actually impress a “person” who is being proposed to. Or, do you have to run a particular process. Gather all the thca and plop it in pentane, cause that’s the easiest way to make diamonds. Takes nearly zero actual talent.
Butane facets of reputable size. Growing sugar is easy.
Pentane. With perfect ratios.

I was reading this material last night before bed, and it kinda sparked thoughts about fast crashing and chalking.
Has anyone tried to disolve isolated thc-a into ethanol or iso, recover solvent, and send the recovered thc-a through an offending closed loop with exactly the same gas? Are we sure that’s the reaction is targeting thc-a?

EDIT: Replied to wrong person
She says a lot of foolish shit sometimes. No offense, but she’s always struck me rather poorly, with a huge ego, and an utter inability to take the smallest of critique. She also blames any critique she ever receives on sexism, which is a pretty weak copout.
It’s either one or the other. She’s saying two things that conflict with each other there.
Is it solvent ratios, or something that needs to be cleaned out of the collection vessel? (asking her, not you)
