breaking emulsion

Yesterday I washed my biodiesel a bit too long on the first wash and it emulsified. I had heard you could break an emulsion by adding glycerin. I tried it on a small batch and it worked! You could see the white emulsion curdle up, and what was left was glycerin on the bottom and what I assume is biodiesel on top- emulsion gone. So I added the glycerin to the large batch, and it also worked. I'm glad to know of this method.
