So I will go into the full process if necessary but in short, I pulled much less than I expected from the first attempt so I did further pulls and received a more expected amount of extract. Basically these are the results of 1 soup and 2 precipitations.
However they are all different as you can see in the attached images.
1. First precipitation, scraped with a spatula direct onto filter paper to dry fast, very happy with this fluffy white beauty
2. First precipitation, left on glass dish to dry then scraped with razor, was still wet and too kages to dry, looks dirty greyish yellow :S
3. Second precipitation, scraped with spatula as before, naptha was yellowish before precip
4. Second precipitation, with razor as before, hello earwax!
So, wat is going on? Is this oxidisation or plant oils entering the naptha?
Some points:
-I am very careful not to introduce any of the lye solution into the naptha
-I try to dry asap but with NO airflow
After spending about 3 hours reading stickies, I hear that this waxxy stuff in p4 is not necessarily bad apparently to the contrary so I will save some to see firsthand.
However, I am looking to purify.
I have done a re-X with hot Heptane once before but resulted into yellow crystal again, not sure if I dried it fast enough.
Is it necessary to do a Zinc wash at this point to achieve the white crystal purity?
