You are not going to be able to find the answers laid out to you anywhere here. But if you know enough about crystallization and the different ways to alter your results you may start seeing other hints laid out that you would have otherwise overlooked.
There have been spoons shared a plenty but the trial and error and experimentation will still be required. But that’s the part that will help you understand it even more.
Are you aware of the demon core? It’s worth the wikipedia binge and YouTube dramatization
Pretty much what I was thinking!
It’s a pretty standard method for crystallization but the trick is the solvent
I thought @Dukejohnson said he was doing it with just butane?
Perhaps I’m remembering wrong.

You can absolutely pull off Ostwald ripening with a single solvent, multiple people are using only butane and some using pentane.
adding an additional solvent can speed the process up but it’s not required.
There’s a lot of different ways to crystallize and you can combine multiple techniques.
I want to try extracting in menthol and then use warm water as an antisolvent. Reasonable? What about menthol/limonene with ethanol or isopropanol as a cosolvent and then evaporate off the isopropanol?
I think i could come up with a lot of bad ideas 
Yea, but how many qualify for the official Bad IdeaTM appellation?
I hear CO2 evaporates well…@tweedledew
I was using another solvent in my fast crash experiments (but don’t recommend) and yes there are more parameters than just that, but it does really change things when you find the ideal solvent (or combo/blend)
Try acetone that’s been dried with molsieves
I love how this thread has turned the word solvent into a mystery
I’ve seen instant crashes by opening up the collection while wet with residual butane, and adding a splash of pentane. Basically add enough pentane so that way when all the butane has evaporated, the solution is super saturated.
Another variable is the temperature. In this example my solution was at the temperature of the evaporation of the isobutane. Evaporation will cool your solution. A hot oven dissolved my instant crash so I need to go a bit slower heating it up next time.
Turpentine and vacuum/heat cycle for sure smell like christmas the lab
Seems reasonable.
I dont think acetic acid and methanol will create a delicious dab.
Maybe for reX or making edibles/capsules/etc but vinegar terps don’t sound deliciius
I agree. But I also think if people are going to use menthol as the solvent most of the cannabis terps would be overwhelmed also.
I found this article a while back and thought I’d share since someone wanted to attempt to use menthol.
I like some regular bho stones or dry sift personally.
Yeah, any alcohol extracts I’ve tried have been devoid of tasty terps
You can still distill a cryoethanol extract and fractionate out the good terpenes and mix back into the cannabinoid fraction for a good vape cartridge recipe.
Distillation of these terp fractions MUST be done at 1x -8 Mmbar and the bf placed in a icewater bath at least lower than 23 C
