I was wondering if the Sodium Carbonate is still good and reusable as a base, after pulling from it? What i do when i extract, is simply do a water extraction on either some Mimosa or Acacia, filter out the bark and evaporate the liquid down till there's just a small amount left, and then toss in pure Sodium Carbonate and allow it to dry. I then pull from the Sodium Carbonate with Acetone getting all the goods and afterwards the Sodium Carbonate dries out and becomes powdery again.
I realize there is probably dried plant gunk with the Sodium Carbonate, but Acetone seems to leave all the gunk behind so i thought instead of having to keep buying baking soda to turn into Sodium Carbonate, i could just simply reuse what i got, atleast for a few more times.
I'm also going to try evaporating the water extractions down to a residue, and make a super saturated Sodium Carbonate water solution which i will then pour onto the residue which should work, hopefully. But for right now i just dump the Sodium Carbonate into the concentrated and mainly evaporated brew, and pull with the solvent to evaporate the freebase goo onto leaves for Changa, and it's the way to go, for me.
Thanks
