Does anyone know what causes suspened glycerin in your homemade bio? I have been happily making for two years now, but seem to have a bad reaction. It seperated into three layers instead of two, one dark, one a little lighter, then normal looking bio on top. When I drained off these two layers, the bio won't filter, the filters keep plugging up, just instantly, without even a gallon going through. What causes this.
Whats FFA, I don't use any animal fats, only completely liquid oils. What do you mean, like reacting the same stuff again? I don't have a pH tester or anything like that, I just do trial and error test batches.
Sounds like a soap layer, a good indicator of to much water present.
Soaps form when there are a lot of FFAs present which indicates an incomplete reaction.
Sometimes you can break the emulsion (soap) layer by heating.
