I have made lye soap before. Last year was when I made my last batch. I also made some with olive oil, coconut oil, lard or canola oil, lye and water. I like the kind with the olive oil, coconut oil, and canola oil best. It is very soft tho, so you have to be sure it is really dry, before putting it away, it will turn rancid and it just plain smells then. It lathers best too. The lard, lye and water is what I make my laundry soap out of.
I found the lye at our neighborhood Ace Hardware store for the price of $3.29 for 1#.
It is very hard to find now adays, since druggies learn to use it for making some kind of drugs. I don't know why they would use lye, but then again, I don't do drugs. LOL
I did find lye in my latest catalog from www.betterbee.com and they had the best price too, at 4# for $9.50, they sell beekeeping equipement, but also a lot of soap making stuff too.
...and may the Lord bless us, with all we need. AMEN
