@drake If you always want your BHO to sugar up, use straight iso-butane instead of n-butane. Extract your biomass with iso-butane at temperatures above -60°C (and preferably above -40°C/F)… you can still do CRC to lighten it up. When you pour, it helps to stir some air bubbles into the honey phase of the purging resin. This combination of treatments will make almost every batch sugary.

@Dr_Jebril The opaline silica actually functions the way it does by having an oxygen lattice “doped” with aluminum atoms.

Would you say that a dry ice/iso cooled system be in the range needed to use isobutane?
I don’t crc currently , dewax only , using n-butane. Am I using the wrong solvent to achieve sugar?

No i can sugar with any solvent. Its all in the purge

You can sugar from any solvent. Senpai @Photon_noir is just giving his Tek for nearly invariably sugar!

What @Slabby and @Krative said are both accurate! Any pure isobutane extractions done above about -40°C/F will usually sugar up, and those done above 0°C dang near invariably sugar up! The best combination for lighter color (assuming mostly clear to milky trichome heads) and occurence of sugar sap is extracting with isobutane around -20 to -10°C.
However, if you pour into a clean, deep glass pan that is scratched up, and then wait for the liquid to reach the consistency of honey (vacuum purge an hour or two), then vent the vacuum (it should have few to no alkane bubbles forming at atmospheric pressure) and stir some air bubbles into the sauce (using a glass rod to micro-scratch the bottom of the pan while you do this will help)… then let it nucleate overnight, at least… you can then start vacuum purging again and turn it all into sugar sap (aka: caviar)!
Otherwise, alternative to scratching/stirring, you can sprinkle some seed crystals into it to nucleate overnight, @Unicorn_Theory1!

It hurts my soul to run so warm. 2 50’ injection coils in a dry ice slurry and low contact times and I’m feeling good about the quality

When you say prime with solvent do you mean running additional solvent through the media after initially “wash”ing it but before you run your actual run through it? Also wondering how much fuel do you want to pass through your crc before using it?
I mean washing as in after you load the crc washing helps compact the cakes and ensure any fine particles make it to collection to be wiped out. If you’re filters are done right you can likely bypass that step. for b80 run 1mic PTFE sheet on top of the sinterd disk. You should also use the depth filter tek ( a rolled sheet of ptfe felt sometimes referred to as the “tampon”)
Priming the cake isn’t to wash it, only to wet it so that when the hydrocarbon solution hits the cakes it does more remediating and less robbing of the desired compounds.
If you’re using the cake just the one time I would also run some solvent afterwards as well just to be sure you didn’t leave any good stuff in the powders.
Thanks for the clarification bud!
Are you in Cali? Is the product state legal? Can I purchase it? How much per gram?
