I suspect this is on your website somewhere, but I can’t seem to find it. Do you use sodium hydroxide? If so, do you make your own from ash, or do you purchase it made by the electricity in water method?
When we make bar soaps we use sodium hydroxide. When we make liquid and gel soaps we use potassium hydroxide. Paste soaps (special order) are a mixture of both types of alkali.
I have made potassium carbonate from wood ashes and water and then refined that into potassium hydroxide when I was in Liberia teaching a couple of years ago. Here in the US we buy it fresh and US made – not from ashes.
All the Best,
