Thanks for your help guys.

downwardsfromzero: I did mean sodium carbonate, you're right. Good correction. I want to give your method a shot. Talking about chem, the thing I lack logic in is ratio's. May be simple, but I want to get it right as to not waste unnecessary yield. So I'll redissolve 1g of contaminated dmt in naptha first. Will 50ml naptha do? Room temp? How much ml acidified water for 1g dmt? pH 3? Room temp? Is one shake and 10 min settle to separate enough? Then discard naptha and evap acid solution. To basify, 1:1 Ha2CO3 : DMT? I have gain alcohol (food grade), which is 96% proof. Will that do or is the 4% water a problem? Ones again, how much ml ethanol should I use? When pulling with ethanol, will there be a residue to be seperated at the bottom? Or is everything left at this point dmt only?

BlazingSatva: Yes I meant bark solution (didn't heat up naptha) I reckon when acidifying and basing prior to pulling, it's good to have higher temp, so the dmt dissolves in the solution better. Then cool down to room temp when adding naptha to pull, correct? Cyb's tek is appreciated for its high yield. But like you say, could this be due to high temp pulls, pulling more than dmt alone. Then again, I heated constantly, instead of momentarily like the tek said. My temp was 65 deg C, if you heat to 30-40 only, might be no problem. Thoughts?

By Earthwalker`s salt tek modification, you mean: ACRB TEK 100g "PICS" (Newbie Friendly)?
