Noman's tek with Vovin's wash followed by a rextaleyesation with bestine in a two container environment containing zinc?

Does this seem like a good plan or should I tweak it some more?

Making purity + crystals.

Nomans tek is old. I'd reccomend cybs hybrid atb tek, wash with sodium carbonate, then recrystal 3x in bestine.

Crystals are not particularly important, just for looks, but the process is very rewarding.
I've not been able to get the yellow out, but the crystals are still transparent. After 3 re-x's & a wash the color may remain, but the purity is still high.

There is a thread around here that shows analysis of different types & colors of spice & they were all in 95-98% pure range regardless of color, even jungle spice.
