This is an attempt to get things in focus for myself at least.

For the sake of precise concepts, gliceryn is NOT an emulsifier.
Emulsifiers contains a clear lipofilic and hidrofilic zones in the
molecule. Which is an emulsifier is the partially reacted mono or
di-glicerides, but in a crystal clear liquid
the glycerin settle before draining it and embarking on the second
stage/polishing step or whatever?

Acid-base aside, there's the two-stage base-base process, which quite

I took a sample from my latest batch of BD destined for my boiler (failed
QT; but very little residue dropped out). It had settled for almost 10 hrs.
That was yesterday morning. Today there is a small, but noticable, bit of
glycerine on the bottom. More settled out after the
