Okay I'll try this again and hope this damn network doesn't bout me and lose THIS post.
So, to my understanding, and I'm no extract expert, the term reaction in this case refers to the basifying of your aqueous solution. The acid boils render the alks into solution by salting them, then when you add lye, the acetate (or whatever you used as acid) molecules are knocked off and the alks at high ph are now soluble in your nps.
I'm sure you know that. But the terminology can get confused easily.
I have always added straight lye, that's the way I was tought, and what I've always read to do. This does cause a(possibly) violent reaction and you must be careful not to blow up a jar, HDPE2 jugs are far more forgiving here than glass-remember drop acid, not the base!
Anyway, as my sig attests, I operate by feel-basify till black-and acacia alks seem to respond well to heat.
Your solution is gonna get hot, there's no need to cool it first, but be careful man.
Best luck, and let is know how it goes, folks are working hard here to establish quality acacia guidelines.
Personally,i love the full spectrum acacia extracts, they are special, and always seem to reveal surprises.
Happy trails!
