Not very much.
But my question is from what I remember (and I could be remembering it wrong im not sure what tek I used but Cyb's Hybrid ATB 'Salt' Tek. But I remember things a bit differently.
Like the steps I remember, x amount of water for it was i want to say 100g of root bark so i doubled all other ingredients. Warmed up distilled water by double boiling (not boiling the root water of course) and stir it up till its all mixed.
I dont recall using white vinegar either but I could have.
Mix in the lye not even sure if i measured it or just put in like a table spoon.. turns dark black/purple..
Now here is another part I could be wrong but I swear I thought I used acetone instead of naptha.. now I could be wrong since at the time I used acetone for other stuff but I could of used naptha I just swear I thought it was acetone.
After that I cover it and shook it around to mix the acetone/bark mix for awhile. Let it rest, then shook it again. Did this a couple more times, then let it all seperate and would extract like normal into a pyrex tray, cover with saran wrap, and put into the freezer.
I cant remember correctly but I know I got a good amount like I got anywhere from 2-3g which i think was a really good amount. And this was my second time making it.. I knoe the first time I did a little over a gram but I also could of extracted more but didnt...
That's all I can remember, not sure if any new an easier teks been found out since. I have some root on the way and want to prepare for it.
