SWIM has performed a couple of A/B's in the past with very healthy results (both in terms of purity and yield), so he's utterly perplexed as to why his current kitchen project isn't behaving as it should. Any advice he can get to help save his troubled extraction will be appreciated.
Anyways...
Started with 1kg Celestial Source pre-ground. It's the brand new stuff (touted to deliver between 1.2 and 1.4%), so he can't imagine his source material being the issue. Performed his normal Marsofold tek with a couple of extra steps. Did 3 separate boils with 3 parts distilled water to 1 part white vinegar (ph between 3.5 and 3.9 throughout), then froze the wrung out powder rock hard over night and did one final boil the next day just for good measure. Decanted and reduced (over a very low flame) down to about 3 litres, then defatted with 3 200ml limonene pulls while still in the acidic phase.
Based up the soup to ph 14, did 10 hot 200ml naptha pulls (but did not heat the jug at any point). Rolled/swirled/turned end over end for maybe 5-10 minutes each time (with a clean break on every one and little to no emulsions) and ended up with a big-assed jar of pale yellow naptha. Did 2 50ml carbon washes with ph 10 sodium carbonate water (drained within probably 30 seconds), one more 50ml distilled water wash (also drained very quickly) then dried with a good sized pinch of microwaved epsom salt (filtered very quickly).
Put the entire 2 litres of now 100% clear naptha in the freezer and got bupkis (or practically bupkis anyway - a very small amount of crystals clinging to the bottom of the bowl), so he evaporated roughly 70% with a fan blowing over the top, expecting to see snowflakes floating throughout, but all this seemed to do was bring the yellow tint back. There are dried crystals encrusted around the bowl where the solvent has evaporated and a very few slightly dirty looking floaters, but this is about it. The remaining 30% is now back in the freezer for about the past 4 hours and there is very little to show for it.
So what gives, extraction professionals? How does my octopus friend salvage his project? Is it possible that carbon washes or a tiny amount of epsom salt could have eaten up his spice? Could the solvent still not be saturated enough? Is the fact that it yellowed up as it evaporated an indication that the goods are actually in there?
