Hmmm. Well I need some advice. I reprocessed and got 3 layers: A dark amber 20% layer on top, a 2% black layer, and a 78% lighter amber layer on bottom. Finally it settled out a thin dark layer on the bottom. I seperated out the lighter amber layer and heated it to remove the methanol. It cleared and seemed to be going well, but when I drained it, it seems to be turning to jelly as it cools.
What have I done? Any input would help. Thanks, David --- In biofuel@yahoogroups.com, "dlgeorgetn" <[EMAIL PROTECTED]> wrote: > Todd, > > Thanks for the advice.
