Sometimes my quality test results in cloudy biodiesel on top. Usually,
though, this is no problem if you have some way to 'dry' it. I simply put
my bubble stone in the biodiesel and bubble away for around an hour. This
will clear cloudy biodiesel that doesn't contain alot of soaps and ffa's.

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
in, maybe not. I thought I'd give it a try.

The suggestion is that you understand precisely what it is that you're

Hi Todd;
When you talk about thickness of layers, is this with the Dr. Pepper

Your comments reiterate what was said, save for one area.

Yes. You are right that we should strive for a complete reaction.

With all due respect, I think you missed my point. I agree that we
should strive for a paper thin interface, ( and I find it is easily
achievable with experience) but when you put information out there like
