Step 4: Step Four: Your Lye is Done

 That's it!  Once the water drains through the ashes filling the bottom bucket with LYE water, To increase the acidity of the lye, take the water and pour it through the bucket again and again.
   You can test the acidity with a PH meter make sure it goes from 1.0 - 14.0  14 is the PH level for making soap.
   Old ways of telling if you lye was ready for soap making was it could dissolve a chicken feather, or if a egg is placed in water it would float above the water like a bobber.
    Or you could boil it, DO THIS OUT DOORS!

<p>This method makes a great solution that will get up to around 11-11.5ph. Great for soap however it is at the end of this inscrutable it is technically potassium carbonate (potash but called lye as well). Adding quicklime turns this into a KOH and chalk mix (caustic potash but also called lye :-/). For soap potassium carbonate is awesome but for biodiesel folks it needs some extra steps.</p>
This is my lye making setup. <br>
hi! lately i'm interested in soapmaking, made my first batch few days ago. i looked for some info about homemade lye and apparently nobody could tell a scientific method to decide when the lye is ready. can you confirm the ph must be 14?&nbsp;how did you get that info?<br /> thanks<br />
<p>get one of those ph testers for a fish tank. its all the same thing.</p>
I got a small battery operated ph meter there cheap and accurate <br>sorry it took so long to reply
David you made Lye? As far as everything I've read there isnt a lot of scientific on this because it was done many years ago when they didnt have access to Red Devil Lye lol. They say that if you float an egg in your lye it slould be level not too high or too low, but floating with about 25% of the egg above water/lye/ Hope it helps why you&nbsp; using homemade lye you can buy it for 6.00? I have a great melt and poor on Etsy karonv<br /> hope this helps
well 12-14 14 recommended, &nbsp;If you need to increase the PH reduce the lye water.&nbsp;
thanks for the answer. another thing: there is plenty of NaOH tables for soapmaking, what about KOH? anybody knows in which percentage i'm gonna use homemade lye? i'm afraid it's trial and error.<br />
This is what i am doing making soap using LYE water, almost all the recipes i have seen have lye and water so i just combine those 2 numbers and use the straight lye water, Also pouring lye water through a coffee filter wil remove teh brow color, use 3 layers of them. <br />
When using. What is weight of liquid used for sol forsoap
<p>Lye is not an acid it's a base. With a ph of 14 it's far from being an acid.</p>
What do you do with the lye water then though. How do you turn it into soap or washing soap. Ta.
i thought lye was a powder
there are 2 kinds of lye, your talking about store bought Red Devil lye. <br>this is how they used to make lye this is also called potash. <br>
Making Lye with Wood Ash is fun to do, but if your ever in a hurry or just dont feel like making it yourself visit www.essentialdepot.com their lye is pure food grade caustic soda (another name for lye)!\
Thank you for your instructables. Helps me a lot since I can't easily find lye in my country here. Thanks again.
lye is alkaline; you can't increase its acidity by making it stronger. as it is an alkali, pouring the water through the bucket will increase its alkalinity (or its strength if you'd prefer to think of it that way) not its acidity (acidity actually decreases as you make it stronger). other than this, great work!
http://www.millersoap.com/phtome.html<br /> A web site with a lot of info about PH testing soap<br />
This isn't sodium hydroxide though, it'll be mostly potassium hydroxide.<br /> <br /> L<br />
Hey I came here to say that!<br /> <br /> Also you're increasing the alkalinity.......<br />
your right i fix ed it<br />
