Question about solvents for spice extraction

I scraped the pan. It was just plant oils and actually brownish/reddish in colour once concentrated. There were a few crystals in there but I couldn't isolate them.
I put this goop in the other jar, poured in the Naptha, and put it back in the freezer. Most of the gunk didn't dissolve. There were no crystals visible in my coffee filter or on bottom of the jar immediately. After a bit more evaporation there are a few tiny bumps on the bottom of the jar.
I have a jar of emulsion, 250 grams of fresh plant material, and only 300ml of solvent. A lot of people seem to think that Ronsonol is fine, so I guess that I should try an evaporation test with this and another with a small amount of the mail order solvent.
You must be right about the defat. I'll have to look into this.
My TEK says that you get much better yields with your second pull. I am skeptical of this and wonder if I should save my good solvent for the fresh material. Would I get just as many plant oils in my second pull or have most of the Naptha soluble ones already been pulled out? My soup has been sitting for days now and still has some of the original Naptha which I couldn't recover.
I did not have a PH meter or anything like that. Can I add too much lye or is it good to err on the side of caution? When I added my measured water some didn't make it into the jar so I added a bit more (too much?). Some lye stuck to the sides of the container that I weighed it in, so maybe my solution is not basic enough.
