I am trying another test batch this weekend (was unable to put the time in last weekend) with different NaOH. A second test batch following instructions to the T gave the same results. I see the results as an incomplete reaction, with the gummy stuff being an emulsion. I suspect my NaOH supply as the culprit. I'll let folks know if this turns out to actually be the case.

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? > Jorge Escobar > ----- Original Message ----- > From: [EMAIL PROTECTED] > To: biofuel@yahoogroups.com > Sent: Friday, June 18, 2004 8:57 AM > Subject: Re: [biofuel] What went wrong? > > > Brian, > > Any other thoughts?
