Letting Biodiesel Settle

"CRAYDON BLAIR: My name is Craydon Blair from Utah Biodiesel Supply, and on behalf of Expert Village, it's now time to talk about letting the oil settle. We have now mixed in our methanol, our lye, our oil on a heated surface. We've got our heat off, and the oil is beginning to settle. It's going to take about10 to 20 minutes for it to settle, and so, we want to show you what it looks like once it's done. This is biodiesel that we just finished. This is biodiesel that's been allowed to settle for a while. I don't know if you can see the difference but I've got a definite settling in here. The top layer is my biodiesel. If you look at the chemistry that we've talked about, we have now biodiesel on the top, and on the bottom, we have glycerin. Glycerin is the stuff that separates out and it's what we want to get rid off so that we can use biodiesel in the car. I'm going to shake this a little bit and you'll notice the fluid up top moves really, really easily but the fluid down on the bottom doesn't move much. Well, that's why we made biodiesel was to get rid of that. And that's how we let it settle."
