I thought I would share my rebatch attempt. I considered this to be an attempt of salvaging soap and to learn from it.
Aw, that is a beautiful swirl! I'm so sorry you had to rebatch it. But I luv, luv, luv the "wet concrete" soap too! Well done!
As for lessons learned...
The purple made gray, tried adding some more purple but stopped because I didn't want to waste that much mica to get a real purple.
That is SO typical of purple colorant. All my efforts to make a pretty lavender liquid soap result in a pitiful gray shade after it's been standing for a period of time.
You were smart to hold off on adding more.
TIP: Develop a habit of lining up all your ingredients in the order in which they will be used. As you add each item, move it from right to left, or, do as I do, I move them from the soaping counter next to the sink to the other side of the sink. One more thing. Before combining the lye solution with the fats, I double-check the recipe to be sure I've weighed everything correctly.
Just so you know, when I was at your stage of learning to soap, I rebatched so often that I became known as the "Rebatch Queen!" For me, rebatching wasn't so much "an art" as it was a necessity.
Thanks for sharing your experience! I'm sure it will benefit others as well.
