This is incredible and invaluable information. My understanding of crystallization was decent but this really thoroughly solidified a lot of the science behind it to a whole new understanding.
I started seeing the smaller crystals form at the bottom of the jar, so I heated it to evaporate solvent and lower the ratio. They disappeared. Left it overnight and the smaller crystals are back. And this must be because I just had re-homogenized the solution, and they were bound to crash back to the bottom anyway? Thatās where this gets a little confusing to me. The other variable was I kept looking at the jar yesterday which moved the stones at the bottom around (agitation) so I am guessing this had an effect. Is it possible, the small crystals I am seeing form will actually grow to larger facets, or is it destined to be sugar?
Obviously the goal was for the larger facets already there to create more sites for the THCA to grow on, now Iām wondering, should I evaporate pentane further, or this will only re-homogenize the solution without creating the high concentrated zone
How did you rehomogenize the solution? Did you stir it up or something?
Can you show a new picture of it?
Also, the diamonds that have already formed at the bottom are the high concentration zone. But when you fish out one of the stones, youāre potentially breaking off and suspending little shards of it in solution. You donāt want any suspended particles if you can help it.
So I didnāt stir it but I feel like the heat caused what I was seeing to dissolve. Here is the best pic I can get of all the tiny crystals that started forming
So all these little specs at the bottom seemed to be there before I evaporated 10% of the pentane. Then it dissolved or so it seemed when I heated and evaporated. Now it seems to be back.
Oswalt ripening is a cycle of forming those tiny crystals, then heating to dissolve them. When next phase crystalization happens you will get more tiny crystals, but also grow your larger stones. Heating will dissolve the tiny ones but not your boulders, so overall they will grow. Wash, rinse, repeat.
Thank you! Like @thesk8nmidget said, I should have looked up Ostwald ripening. Just busy with work while trying to do this and keep up with the thread. Appreciate it man
Ostwald ripening is the phenomena in which smaller particles in solution dissolve and deposit on larger particles in order to reach a more thermodynamically stable state wherein the surface to area ratio is minimized.
Yeah and since I heated and dissolved those, even though smaller crystals are back and have formed at the bottom again, ive since seen the large stones get larger. Itās working!
Iād sell that 22gram Boulder as one and just charge double lmao
I believe what theyāre saying is if u can get all the Lil shit dissolved then toss ur seeds back in itāll continue growing the larger ones ā¦might have to add 10% pentane back to keep larger structures growing and not smaller ones
He said he evaporated 10%. I figured thatās probably one the main reason itās started depositing new small stones?
I know nothing though Iām no body for real
I can grow stones but do I understand everything about it no
But couldnāt he raise it back up a Lil dissolve the small shit and seed the jar w his large stoneā¦otherwise itāll keep making new smaller stones
Basically Iām getting his solution back to where he started at but w everything thatās small dissolved and dropping the big stones as seeding a jar
Iām basically trying to treat the jar as new jar w seeds dropped in
Just after we evaporated 10% the pentane he said then the small shit started formingā¦can we keep this from happening and have all the thca go to the seeds mainly?
Iām kinda thinking adding a slight bit of pentane perhaps like 3% at a time back and then seeing at what point the tiny crystals stop forming? Thatās IF I decide to add it. However with the larger ones getting larger it seems theyāre still getting a lot of the suspended crystals to stick to them? But who knows. And is it certain the small specs (that i posted in the recent picture) wonāt grow into somewhat decent size stones as well? I write everything down so Iāll just keep updating this thread as I go
I was under the impression your jar was actually starting to sugar up. Those little crystals are staying put near the bottom and theyāre growing, just leave it now its doing what you want it to.
So can I askā¦ this is what I should have seen relatively quickly when I first started the ReXing? And thatās how I would know the concentration zone is working? Which means I believe I have found some great data through this project in terms of ratios for growth size and speed!
