I’d expect if you see zero crystals forming after letting it sit for a few days on its own, there is probably no THCa left in your oil as it sits.
Older flower is usually partially decarboxylated, and looking at the pictures of the oil it appears this might have been the case.
If your oil is over 60% THCa it will precipitate THCa on its own after sitting, even with residual butane or pentane present.
I’d suggest starting again with some more fresh material if possible, keep temps low during extraction and purge. Just let the dish sit and evaporate the butane naturally for a couple days if you have no vacuum oven. If sitting outside or somewhere exposed to dust, place a T shirt or other cotton fabric over the vessel with elastics to avoid dust and bugs.
Ok…non polar butane cold, pour-off , T shirt and boom THCA self purifies… it is no wonder there is no theory! One bucket , a T shirt and a Pyrex dish its a wonder. @Aurion , can you give me a time course for extraction process? Can it be done with 30 seconds of biomass exposure, 3 minutes or 30 minutes…what can you say about the time course?
bro he’s clearly working with a few grams, not a few kilos, why would you suggest mass production tek for him?
OP, just stick your stuff in a warm oven at like 80-115f, it should crash out everything pretty quickly, if it just stays a sticky sap then you dont have enough thca left in the material.
Ur way works for large jars also if extracted sub zero -35f to -70f so its more clean and pure .all u need is heat or time room temp and high enough thca vs terpenese and itll crash everytime
And if its crcED. Aka CRaCked lol it’ll do it without even trying. But ur thca % must be high enough
Also if u grab to many fats wax and lipids that some stains have even extracted cold it will hender crystallization
