Hello Shawn. You were looking at all methanol soluble components including
the glycerine which is rather soluble in methanol. Separate the glycerine
next time.
Best regards

Shawn,
I suspect that the dense substance at the bottom of the flask was
unreacted glycerides, indicating an incomplete reaction.
I now drain a sample of the mix towards the end of processing.
- Shut off the pump
- Drain a sample and turn the pump back on
-
FWIW - I let the batch settle for a week or so (the lazy man's way) and
that also seems to help w/ this.

Shawn,
I see that Jan W replied to your post.
I hope I didn't confuse things with my earlier post
Do as he advises.

Well, I'm not really a greybeard, but since I've been settling both the
crack and the wash

Hey Tom;
Take a sample from your fuel after settling 6-8 hrs and set it asside in a
mason jar for the longer period and see what settles out. Rod believes that
glycerin settles slower in a poorly completed reaction

I wonder why
Well I'm no chemist but my guess would be that the large Mono and Di and
triglyceride molecules that are left are jammed in between the ester
molecules and the glycerine has to jostle
it a try.
