My son in law made biodiesel by mixing lye with fat. It produced both
the biodiesel as well as glycerin. Now it is my understanding that soap
is made the same way. Does anyone know why some people end up with
biodiesel and others soap when those two are mixed?

So if you buy a soap without glycerin in the list of ingredients, it
can still have it. Comments please.
