From my experience it's probably caused by a slightly incomplete
reaction or a bad wash.
YMMV

Could it be polymerized fuel? BD, especially that made from soy oil
doesn't store well (4 - 6 months?). I've read/heard that polymerized fuel
can clog filters. This may be a problem for commercial producers in the US.
Homebrewers shouldn't have much trouble using their BD within a few
Good Day All,
My question is in regards to the Quality test develop by Jan Warnqvist. Is
this test to be performed on the product before or after the glycerin has
been removed, or does it matter. I performed the test with out removing
glycerin and found that I got a clear bright phase except you
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.

LOL LOL but the best one is Evian water. Evian is NAIVE spelled
backwards!! Perfect. (said it here b4)
BTW here are some locals who are not just emailing web forums on this
issue. Take action. It is amazing how fast theis group mobilized and
how much effect they are having.
The little island in Maine my family hails from did that as a joke -
they have a large fresh water pond and bottled and sold the water in the
one store.
Made a pretty penny. Of course, the water does taste good, but it's the
same stuff that comes out of the tap in the houses.

Mike,
I let mine settle for a week when I can. It washes much easier. I doubt
that it does anything for an incomplete reaction though. That is to say, I
don't think the unreacted oil will settle out.
But:
I have been wondering about something.
When I started making BD it would
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
believe he is right. And yes it only takes a little glycerin to
Well, I'm not really a greybeard, but since I've been settling both the
crack and the wash I haven't seen any white gunk in the clear filter.

Do you let the wash settle longer too?
When I'm not in a rush I let it settle for 12 - 24 hrs between washings.
After the last wash letting it settle for a couple of days makes drying a
snap cubies in the sun.
I'm not sure what you mean by white gunk in the clear filter, but maybe
you're
Hi Joe,
glycerin settles slower in a poorly completed reaction.
I wonder why
Interesting experiment.
I make two grades of BD
Good: passes quality test; used for car
Not so good: fails QT used for boiler (heat)
I could take a separate sample from each

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
