Lye

biodiesel makers use lye, so you might be able to split costs if you can find someone local.

if you are in MA just get it from Astro Chemical in Springfield. It comes in 50# bags.

what do they get for 50 lbs? That would make an awful lot of soap. With the government the way it is these days it would seem like you'd need some special kind of permit or something to buy that much at once.

"Where do I buy the lye?"

Ebay -- Search for Sodium Hydroxide -- Can't miss it

We make a lot of cold process soaps and get all our lye from AAA Chemicals. I have spent a lot of time searching for the cheapest lye (including shipping) and these guys have it, their lye is top notch stuff, and their containers are great (we buy the 2lb bottles, 6-8 at a time, which last all year).
