I let some of my BD settle for about 2 months (indoors, 22 degrees celcius) and by the time I got to the washing stage I noticed that it was rather clear with some white sediment at the bottom. And when I washed It I did not observe much soap formation. And the separation was almost immediate like I was mixing vegetable oil and water.
Now after two days the water still looks fairly clear. The bd is slightly cloudy. First I worried that I hadnt completed the process and that what I was washing was more vegetable oil rather thatn Bd, but reprocessing it didn't give any glycerine. Is there any error here?

The more glycerol/soap that is extracted by settling the less impediment to the subsequent step, whether it be stage two or washing.

It?s necessary to settle so many time? It?s bad if any glycerine is not decanted and is mixed in the second stage? Is there any "trick" to avoid to wait 12 h between first and second stage? > >Many thx in advance and sorry for my bad english > > > _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.or g Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/ _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
