I took 50 g MHRB and acidified with 4 mL 30% HCl in H2O and 500 mL dH2O. The pH read around 2. This was heated for a little bit but I realized my heating pad was too variable so I just let it soak for a week. After the week it was twice filtered and basified with a solution 3 g NaOH in 7 mL water which caused the color to change from Reddish/Brown->Grey->Oily/Inky Black. The pH read around 13. 50 mL of Naptha was added and the solution was shaken. The emulsion settled within 6 hours and after 24 hours the Naptha was pipetted into a pan which was stuck in the freezer for 12 hours. After those 12 hours, nadda, nothing, zip.

What went wrong?
What can I do to fix it?

My thoughts would be to much acid, or too little base.

Could be that you used way to much naptha and too few pulls?

I use say about .5ml naptha/ gram bark, and I do say 4 pulls, il also evap the naptha down till it gets cloudy when blown on. It makes it easier for the DMT to crash out when the naptha is saturated.

I was going to do more pulls, but just wanted to see how the amount of DMT per pull changed.

It sounds like your naptha wasn't saturated enough to precip.
One should do multiple agitations with thier NP.
Could be the lack of heat in the acid soak too - I've never tried a CWE with HCl, but phosphoric CWE's yield significantly lower than when the solution is cooked.
