yes and no, you want to stay in the metastable saturation zone.
This chart shows the general idea, although its not specific to cannabinoids.

Which Alkane is best for this? Wouldnāt propane or butane dissolve crystals? I couldnāt find anything marketed just as āAlkane.ā can you direct me to it if that is a thing?
Also, to purge off the āAlkane,ā does the temperature used to boil it off depends on the type of Alkane used? Or what temp am I shooting for with whatever solvent your using? Donāt want to lose any of those residual terps.
Gracias Amigo
Sounds like most people are just washing with pentane through a vac and funnel

Yes itās going to dissolve the crystals micro bitsā¦ The idea is to do it super super cold, like dry ice coldā¦u minimize the amount crystal loss and the fast filter paper minimizes solvent time
If you do it ever a fast filter viper youāll get most the terps off within the first wash, I like I use ETOHā¦ Much easier and cheaper for meā¦ And yes if warm your dissolve them

So let me make sure Iām following here. Apologies for any redundancyā¦I want to wash with a pentane; or ethanol? And either solvent I choose I want to make sure it is at ultra-low temps. And once dissolved Iām pouring the cold solution rocks and all over a fast flow filter paper and pulling it through. Iām guessing around 25 microns is good for this. Should I go smaller/larger? And finally whatās the best purge method for this? Pretty low temp in a vac oven Iām assuming to preserve terps. Any vac necessary? Or is the roto really a better way to purge off the solvent? I feel like I wouldnāt have enough terp sauce to justify that method but Iām all ears. Thanks again gang for the quick responses.
I think pentane is your best bet and yeah probably cold as ypu can get it using a bucnher funnel should get the funnel cold too i imagine i think i may have seen something about letting them sit in pool for quick second in funnel right before you vac to get a good clean but try hitting the search engine i know theres more better thorough sop here

Are you going for a full thca isolate?

My fresh frozen run had not started forming diamonds after almost 2 weeks so I seeded it with 2x .5ct diamond chunks and within an hour diamonds started forming

Iāve only crashed diamonds once without a seeder. And that was actually my most recent run into the miner

Good question. Lol I thought thatās what I was trying to do but Iām not positive I know what you mean exactly Is that just the difference between separating terp/cannabinoid sauce completely from the crystals or leaving them partially mixed? Iām going for those nice crystal clear faceted shards. I have big lunkers in my jars but when I pour off the juice they still have a slight tint. Thanks for chiming In as well. Super Grateful for all the insight offered here.

Iām glad this was brought up. Iāve never had a problem with crashing until recently. Itās been a couple weeks and thereās just a couple dab size crystals in each of the three jars of afgoo Iāve got cooking and The Constantine I ran the same day is almost done. The afgoo was def thinner with more solvent left in it. If I drop a seed crystal in and it dissolves could that mean there is too much solvent. Donāt think temps are too high at around 85, which would be my other guess. Iām gonna plant a seed and see if that helps but since you purposed it, rhetorically or not, what else could it potentially mean if the seed does disappear?
I can think of only two possibilities, ātoo much solventā, and ānot saturated yetā.
Those are only subtly different, if they are different at all.
Which shows what I know, because one could also answer ātoo hotā and be correct as well.

Iām going to guess that you might not be dewaxing well enough for you to not be able to get clear facets.
And definitely. If you are going to drop in a seed, you donāt need much solvent remaining.

To clarify, the crystals look like they would be clear if they werenāt covered in terps. I just want to clean em up so they are completely separated from each other.I can take pics tomorrow if that helps.
And thank you for clarifying the solvent/seed thing for me as well. Iām gonna purge off those jars a bit more tomorrow before seeding them.
Oh ok. Dirty diamonds not dewaxed well enough will look all thick and not clear like that. I wasnāt sure what you meant. I like a little terps on there. But finding that happy medium is a personal thing, I suppose.
And youāre going to be looking for almost a NyQuil kinda consistency and you can drop in a seed. Not to worry about the one that dissolved. You just made your yield a weeeensy bit more. Haha.

This is back before I was using heatā¦they where never clear then but are now Everytimeā¦I havenāt washed in while thoughā¦
Scroll up few messages for instructions to wash stones via @Soxhlet instructionsā¦
As u can see worked like charm and was my first time ,I made several mistakes!
Now that I know how to use the buchner funnel better I was never getting sealed seated before which was probably only reason I lost so muchā¦the vacuum wasnāt really helping like I eventually got it doing , bc the paper not being sealed , which was when I was winterizing with same system later in the year

How does -80 etho work for washing em. I havenāt tried it yet. Pentane, ya and itās easier to precipitate in. Buuuut, if I just wash em quick with etho and re-dissolve (yes evap etho) in butaneā¦ I can do that tomorrowā¦ 
get it colder if you can, more loss than pentane but not as gross to smoke the residuals. have you played with wiping the crystals off with a lint free paper towel? Thats how I clean some of the āsharkteethā.
