Hi there fellow nexians

I'm about to prepare for my second extraction and have been reading a lot of wisdom since my first extraction, which was a big mess

I did an A/B extraction from the DMT Handbook tek, using MHRB instead of Acacia Obtusifolia which they use in the DMT Handbook. My end result was a big pile of black brown gunk with yellow gunk underneath! I cleaned it up with some hot water with NaOH and Naptha and siphoned the layers much more carefully, and got this yellowish flake-like spice, which was absolutely awesome!

Then I bought some separatory funnels, purified my spice, till it was as white as the purest snow and as dull as it was white
Lately I have read Entropymancer's posts about extractions and Jungle Spice which I am pretty confident was what I got from my first extraction. So my questions are:
- If I want to be sure of getting jungle spice should I skip the defatting step in extractions. And maybe even go and make an STB extraction instead of an A/B extraction?
- I did get this beautiful result the first time with an A/B extraction, but was this a lucky consequence from my first-time-sloppiness? Is it always a good idea to acidcook - does it ensures me a bigger yield? Or should I avoid it if I want to get this other alkoloids?
- Also, are there other impurities that I should be aware of that can cause same colorization? And maybe some tips to how I can tell them apart? (if such a thing is possible without professional equipment)
- And at last I'd like to know if NaOH and lye are the same thing? If not: Are Sodium Carbonate washes always important or only when using lye?
