Thanks for the reply. Sorry for the sparse info, this is SWIM's third extraction of this wonderful sacrement and is hoping to learn and perfect a single extraction method that he can do every time to produce some quality spice. Basically the tek SWIM followed went like this:
NB: No litmus papers used
1. Added 1 litre of de-ionised water (battery top up water) to a screw cap bottle, added 25g of NaOH.
2. Once cooled, added 100g MHRB, shaken for a few minutes and left overnight (speeded up process in a warm water bath was an option). Solution went black as in previous extractions (all two of them

)
3. Warmed up Naptha (Ronsol lighter fluid) in a hot water bath and added to the mix (3 x pulls of 40ml naptha). Gently tilting/rolling the naptha in the mix for 10 minutes and letting settle for 15mins each time. Confirmed visualy that the amount of naptha had settled to the top again was equal to what was started with. Pulled this into a jar, then decanted a second time to remove any impurities and put in a pyrex dish.
4. Once all the naptha was now in the pyrex dish, evaporated approx half of this.
5. Just before half of this evaporated, the naptha went very cloudy and large deposits of white were seen to crash out of the solution. The solution then went a little bit clearer.
6. When the naptha was placed in a jar for the freeze precip process the left over "white substance" in the pyrex dish dried almost instantly. It was whiter than SWIM's previous extraction a few weeks ago end product after re-crystalising! And it had sparkly crystals in it.
After 3 days of the spice being in the freezer (SWIM rotated 12hrs in freezer then 4 in the fridge, back in for 12 in the freezer etc..) SWIM produced 1.1g of fairly white crystal structure. Had a lot more structure than previous attempts (looked a lot more like crystal as opposed to powdery spice he pulled before). The powder scraped up from the pyrex dish after evap'ing and before the freeze precip process amounted to approx 200mg. Working it out 1.3g of spice from 200g MHRB gives 0.65% yield? How does this sound to other psychonauts?
SWIM thinks, to be fair to this above tek, it has produced some really nice crystals, better than the STB tek he used before. Just seems a smaller yield. An easier process and much less NaOH compared to spicey cat's tek (125g NaOH-850ml H2O-100g MHRB). The only real difference it seems was using de-onised H20 (battery top up water) as opposed to normal bottled H20.
From this point, SWIM is thinking is it also worth re-x with this pretty good looking already crystal to further purify? SWIM has 300g of root bark left and is deciding which tek to follow for the remainder.
Hope SWIM has covered everything! Thanks again.
