see my post above. I’ve been making soap for 25 years, so when I saw the lumps come from the bottom of the pot, I suspected I had uncolored batter until I actually cut the loaf. The white spots are so different from the rest of the soap that it was easy to identify them as an issue with lye. Uncolored batter will have the same/identical texture as the rest of the soap.
Hard, shiny, irregular, bright white spots indicate an issue fully incorporating the lye solution. After reading my posts, if it ever happens to you, you will know it when you see it!!! I’m wishing I took more pictures to share.
