Im having the same thing as Brian...I did the washing in a jar and i got the same. The 5 gal. bucket that i was processing it turned with a gummy stuff on top and underneath that layer is something like used motor oil. I did everything like the instructions,but something went wrong.It seems like the glycerin went to the top and nothing to the botton of the bucket. somebody tell me what i did wrong?

Brian, Any other thoughts? Other than going back and adhering to the instructions more precisely? Nope. Not a one. What you apparently have is an incomplete reaction on the base side, leaving you with a compliment of esters and emulsifiers, the latter being unreacted mono- and di-glycerides.
