You could do mini batches of one liter, done in a 2 liter pop bottle. On the best biodiesel discussion board in the world (not that I'm biased...http://biodiesel.infopop.cc/eve/ubb.x/a/cfrm/f/498605551)this is known as the World Famous Dr. Pepper technique, as popularized by a biodiesel wizz who goes by Tilly.
Anyway, the idea is, you put a liter of oil (or glop) in a 2 liter pop bottle, and then add a bit more methoxide (methanol + lye (sodium hydroxide, you knew that...)). And see if it helps.
You're pretty much screwed as far as determining if you have water in the batch, because if you boil it to check for lower weight, you'll boil the methanol off too. So you won't know if the change in weight is due to the water or due to the meth.
You can burn the glop, but it's got to be done in a nice hot fire, where the glop is NOT the primary fuel source. Think nice hot wood or coal fire, outside, built around a can, to which you add a quart at a time or something. Or you can build a "Turk" burner, which is a forced draft thing, then feed it 50/50 diesel and glop just to get rid of it cleanly.
I have read several sources that say glop makes really good herbicide. And the meth just evaporates with lots of fresh air dilution, so that shouldn't be a big deal. I have no first hand knowledge of disposing of glop however...
Good luck and have fun!
