Is my extraction over simplified?

[Spacewalker]

So iv read through alot of extraction processes but iv gotten great results with mine. My only concern is that it seems to simple. If i am doing something ridiculously stupid please let me know.

1. Mix 4oz of 100% lye in 2 liters of distilled water and shake in glass jug.
2. Move to two liter bottle and add 4oz of bark. Shake well for 5-10min.
3. Add 1/2 inch layer of namphtha and shake gently for 5min
4. Remove namphtha layer and let evaporate in glass dish.
5. Scrape crystals and talk with the gods.

I can get a little less than 10 grams out of a kilo of MHRB. My crystals are pure white and send me on a wild ride. I just want to know if I'm missing some step that is crucial to my health.

1- Dont shake in a glass jug, thats recipe for disaster because as lye dissolves in water it generates heat, which generates pressure, which can make glass break and leak or explode. Maybe it didnt happen yet but one day it could. Just add the lye slowly while stirring with a wooden or stainless steel spoon). Also be sure to wear goggles and gloves.

2-Plastic bottle? Dont, if you care for your health: FAQ - DMT Frequently Asked Questions and Troubleshooting Guide - DMT-Nexus Wiki

3 and 4- spelling correction: Naphtha, not NaMphtha

Also I suggest just for the sake of trying sometime, next time divide one of the pulls in half, and half of it freeze, half of it evap, see what you like more. Also, get part of your evapped crystals, and redissolve in non-denatured ethanol or acetone if you can get some, and evap again, to help getting rid of solvent traces inside the crystals. Maybe you decide its not worth it, but do it at least once with part of the crystals and smoke both crystals to see if you notice some significant difference.
