Hi guys, unless i'm misunderstanding, it sounds like you're talking about cleaning up finished bho using etho and winterization?

I extract with butane, add everclear (a ratio of 2:1 butane:everclear) - and i've been doing this method forever, and im thinking perhaps im wasting a lot of everclear. Because i don't necessarily know what the final oil yield will be, it's hard to guage using the ratios listed above in this thread. Anyways after the reaction is finished, i put it in the freezer overnight, strain it, evap on ptfe, vac it, and have slabs of lovely winterized shatter.

Im always looking to improve my technique starting with getting ready to pull the trigger on an mk III very soon, but i'd love any insight on the amount of everclear.

The amount of everclear depends on what is present in the raw oleoresin. You must have enough that it still flows like alcohol at 0F, rather than like thin oil.

Part of me trying to figure this out, is that when i do have my cls, i want to be able to know how much etho to add to the shatter platter, but maybe it's just an eyeball thing and i'm trying to be too much of a scientist about it?

I'll give you a recent example. I used about 112 grams of dried flowers, and had 1L of liquid butane after blasting. I added 500ML of everclear (as i've always done), and once i did the rest of the process, that ended up being around 24 grams of shatter. Evaping that much etho for only 24 grams - i wonder if i'm using far more everclear than i need to. 500 ML is a LOT of liquid to evap down to a puddle that was 24gs after vac - so i wondered if i could have achieved the same result with 100ml or 200ml - i'm eager to learn.

I'm not sure how the solubility of oleoresin is affected by amount of etho - can too much be bad? Thanks in advance

Is there any way to recover the everclear when winterizing, rather than just evap?
For edibles and such I just use my still to reclaim, but what about keeping it cool and non-decarbed?

Thanks!

I'm sure you could design something to recover it. Similar to a Closed Loop System for Butane recovery. If anybody has any experience with this I'd be curious to learn more.

Dang Piper, I remember doing that not too long ago. Gathering claim is seriously a labor of love.

You can just vacuum distill it. You'll need a magnetic stirrer hot plate. The other way is a rotovap but they are expensive.

If it still flows like alcohol at 0F, then you have enough. If it flows like oil with some alcohol in it, add more.

How much you add doesn't affect the oleoresin, but how you remove it does.

Thanks!

What DM said.

You can boil at lower temperatures under vacuum.

And to recover the alcohol from the vacuum chamber, a cold trap on the out take?

Yup!
