I believe that you come up with a different kind of lye from wood ashes. The kind that makes liquid soap or hot process, not cold process. What you want for cold process is Sodium Hydroxide and ashes makes you Potassium something-or-other and is supposed to be very variable. That is why the hot process works, they just boil it until the concentration becomes the correct balance and it reaches trace. But that kind of soap is supposed to be quite harsh.Denim Deb said:Does anyone make their own lye from the ashes in their wood stove/fireplace?
From my understanding, ash lye is actually a mix of potassium and sodium hydroxide. You can use hot process with commercially manufactured sodium hydroxide as well.savingdogs said:I believe that you come up with a different kind of lye from wood ashes.

People who make meth use sodium hydroxide and so in some areas it is harder to obtain now. We did not find it at a hardware store but I've heard it is sold as a drain opener, you just have to make sure it is 100 percent pure.
On some of the soap threads, they were discussing how you could be on an FBI watch list for buying this ingredient! So I felt safer purchasing it from a soap supplies company so it would be understood automatically why I wanted this product and I got some fragrance at the same time for the same shipping. I wanted to make it from ashes, too! If you find out something different, let me know.
