I heard a report on the BBC World service about water cremation which uses KOH. I will start a new thread in the general area to not hijack this... but it is fascinating.

Yikes! I don't even want to think about that! Totally freaks me out .....

I have another question.
I purchase my lye fro one specific vendor, but have a bottle from another vendor that has a little bit left, maybe an ounce. The one I use now is more like pellets, the other one looks more like dust-ish.

Can I use them together on my next batch? Or not?

I don't see why not. I would have no qualms doing it.

Yesterday I went to the mall and into the book store to look at books while waiting for my son. Of course I went to the soap section, and I was reading about lye.

I wish I would remember the book I had or taken a picture, but I didn't.

It was talking about injuries, and how getting burned with lye is an instant process? Is that a fact? I thought a person could get splatter, and not see the injury for several hours. But I am probably wrong.

A chemical burn from NaOH or KOH happens pretty fast, yes. But whether you feel it or not depends on the circumstances, the toughness and thickness of the skin involved, how much NaOH (or KOH) got on the skin, and on your tolerance for pain/discomfort. Like most things, context is important.

If I get a tiny droplet of NaOH on my forearm, it can take a few minutes for the NaOH to work through the surface layer of non-living skin and reach the living tissues. At that time I might feel an itch or a sting of pain, but it's possible the NaOH might be mostly gone due to reacting with the non-living skin. I might or might not end up with a small chemical burn to the living tissues.

If the same tiny droplet ends up on my face, throat, under the fingernail, or other area of delicate skin or mucous membranes, the pain and injury will be really fast and nearly impossible to ignore.

Have you ever handled zappy (lye heavy) soap, washed your hands, and noticed your fingertips felt super slick when you wash them? And after drying them off, your fingertips feel really dried out and later on they're really rough? That's from the NaOH dissolving the proteins in the non-living layer of your fingertips and essentially damaging that protective layer. Will that cause a chemical burn to your living skin? Maybe ... but maybe not if you wash quickly and thoroughly enough.

And larger splashes ... yeah, that's going to hurt and cause damage pretty fast, no matter where it lands.

The heat burn is instantaneous. 250 degrees is a pretty stinking bad burn.

The chemical burn... in my experience, not so fast, but Deanna's already got that answered.
