Lye Calculators

Thank goodness for lye calculators!!

Don't get me wrong...I love a challenge just as much as the next person but picking up a pencil and paper to figure out how much lye is needed for a new recipe I want to try isn't my idea of time well spent. Not with the vast array of free calculators on the web begging me to use them. 

Some not only tell me how much lye I need, but also help me to answer questions like 'Will these oils produce a good lather?' or 'Will this recipe make a conditioning or cleansing bar of soap?'.

This information is valuable to a soap maker....it takes some of the trial and error element out of soap making. We have enough of that already!

Lye calculators have become a necessary tool for soap makers. They provide us with the ability to quickly and easily recalculate old recipes or create new ones...all at the click of a button.

Below you will find links to a good selection of these wonderful tools and a few details about each one.
