Dear Paul, My third wash left almost crystal clear water, and after settling for 2 daysd, the BD is definitely transparent and non-cloudy.
Today I continued with 4 litres of BD (four 1 liter batches). I´m still in the glys-BD settling stage, and the BD looks much more brownish than my first batch, and still cloudy. I´ll give it a day or so settling to see what happens. Anyway, if too much lye forms that sticky gel and too little forms a third layer of unreacted WVO, then if I only get a layer of glycerine and a layer of WVO, my proportions should be right, right?. And very little whit residue (soap?) is left on top of the glycerine layer. However, the first wash is very dirty (white, milky cloudy almos foamy). So what should I change to get less soap formation?. Supposedly less water? Can I wash indefinitely (say, three or four times) to remove all soap? Best wishes (+ thanks in advance), Christian ----- Original Message ----- From: "Paul Gobert" <[EMAIL PROTECTED]> To: <biofuel@yahoogroups.com> Sent: Sunday, April 14, 2002 5:18 PM Subject: Re: [biofuel] Fw: cloudiness > > ----- Original Message ----- > From: "Christian" <[EMAIL PROTECTED]> > To: <biofuel@yahoogroups.com> > Sent: Monday, April 15, 2002 2:27 AM > > My batch of BD settled the glycerine out nicely, though the BD still > seemed a bit cloudy.
