Pure sodium hydroxide is also used in soap-making, which is both fun and legal. I really hope it doesn't become any more difficult than it is to get ahold of it.

I don't think people should do meth, but I do wonder if the total social costs of making it illegal (crime, meth labs near and in residences, incarceration &c.) outweigh the costs of allowing it to be legal.

Is the stuff sold as drain cleaner not suitable for making soap?

My local big box hardware store sells 100% lye drain cleaner for $4 a pound (it's 100% sodium hydroxide as crystals or powder). I haven't tried buying any, but I doubt a couple pounds would be an issue.

The 100% lye stuff is, but as the former poster indicated it isn't really the most effective drain cleaner — and there have been moves to make it illegal, because of its use in drug production.

I have to give my phone number whenever I buy it. Galling: I'm a free citizen of a free republic, and should be able to purchase chemicals without being tracked.
