You see, lye (sodium hydroxide) is formed when wood ash (which is mostly potassium carbonate) is mixed with water. The mixed solution is extremely alkaline and if it comes in contact with your skin, it begins to absorb the oils and turns your skin into soap.
How do you make lye from wood ash?
To make lye in the kitchen, boil the ashes from a hardwood fire (soft woods are too resinous to mix with fat) in a little soft water, rain water is best, for about half an hour. Allow the ashes to settle to the bottom of the pan and then skim the liquid lye off the top.
What happens when you mix ash and water?
When you mix wood ash with water, you get lye, which is a common ingredient in traditional soap-making. Throw in a form of fat and add a lot of boiling and stirring, and you’ve got homemade soap.
How do you make potash soap?

- Separate the soap from the lye the next day.
- Heat the soap again.
Where does lye come from naturally?
A lye is a metal hydroxide traditionally obtained by leaching wood ashes, or a strong alkali which is highly soluble in water producing caustic basic solutions. “Lye” most commonly refers to sodium hydroxide (NaOH), but historically has been used for potassium hydroxide (KOH).
What does lye do to dead bodies?
A body is submerged in a solution of heated water and lye. After a matter of hours, everything but the bones dissolve into a liquid made up of water, salt and other components safe enough to go down the drain. The remaining bone fragments can be crushed into ash for scattering, burial or memorialization.
What is the substitute for lye water?
If you’re baking and need lye water but are unable to find it or don’t have the time to go out and get it the first and most appropriate substitute is a baking soda solution. The humble baking soda can be used in place of lye to create a solution that will substitute your lye in many baked recipes.
Is ash good for skin?
Wood ashes alone are said to be nontoxic. A poultice application of wood ash and water is touted as a folklore-remedy for pain relief. Wood ash plus water create a strong alkali that is capable of burning human skin. Wet wood ash can cause full thickness burns and necrosis given sufficient skin contact time.
Is ash mixed with water toxic?
After a fire, windborne material such as ash and soil from paddocks with inadequate ground cover may be blown into streams. Once in the water, organic materials provide ideal food for bacteria and algae. It is believed the water is not poisonous to livestock, but it may be harmful to young or weak stock.
Can I add potash to my black soap?
Potash is ash that comes from different sources, such as cocoa, plantain, and clay. Any of these will work for black soap, but they may affect the final color and texture.
What can be used in place of lye?
The main way that you can make soap without handling lye is by using melt-and-pour soap. It’s already been through saponification (oils reacting with lye) and is safe to use and handle straight out of the package.
Can lye really dissolve a human body?
Heated to 300 degrees, a lye solution can turn a body into tan liquid with the consistency of mineral oil in just three hours. When the five- to eight-hour cycle is complete—that’s three hours to destroy the body, plus a few more to heat and cool the solution—the liquefied remains are safe to pour down the drain.
How is wood ashes used to make potash?
The wood ashes were collected into a pot with water, and then leached to produce lye. At this point, the lye solution was a basic phase of potash and could be used to manufacture products such as soap.
How is lye solution used to make potash?
The lye solution could also be processed further using heat (either boiling or baking) to evaporate the remaining water; this evaporation process produced potash. Early potash was used to make products such as soaps, dyes, glass, baked goods, and gunpowder. With so many uses, the demand for potash constantly grew.
What can you use wood ash for lye?
For my purposes, lye refers to any compound of high pH (alkaline aka basic) that are required for soap making or bucking animal hides. With winter approaching, I explored ways to use the wood ash produced from my catalytic wood stove.
What can I use to make lye out of?
Here we will make Lye Water out of certain wood ashes and “soft water”. 1) White Ashes Dried palm branches, dried out banana peels, cocoa pods, kapok tree wood, oak wood, (or for really white soap, apple tree wood) make the best lye ashes. Ordinary wood used in cooking fires will do.
