My two cents (or two dollars… I”m never brief enough for cents): I think that we are generally too quick to rebatch. There are a number of reasons but the main one is that you can learn a lot more about soap by waiting than rebatching.
You need to know what is wrong with soap before rebatching it. You can’t fix a problem you don’t understand. For right now I’m addressing rebatching lye heavy soap.
First, everybody should know for sure what a zap feels like. I hear “you’ll know” too often. I’m not certain you will know. To find out, purposely zap yourself on thick trace soap batter that you are all ready to pour from a CP batch. It’s going to zap so be ready to BARELY touch your tongue to it. Now you know what it feels like.
Lye heavy soap will lose its extra lye. All it takes is time and air. I would have added loads of knowledge to my soap “base” if I had just waited to see what happened. (I’m talking pre-Internet, and pre-soaping books) Even if lye is not the problem, waiting to see what a “failed” batch will do over time will give you a lot of insight into how soap works. Leave the batch alone. Get it out of the mold if it will come out – so you have your mold to use and forget about that soap in some well ventilated place.
In the mean time, go over your recipe and your memory of what you did. Check the recipe in soap calc and with your “soap advisers” and if it looks good, make that same soap again. Yes. Now. Exactly the same recipe, same coloring and same scent. Do a small batch but never leave a failed soap, failed. You’ll be amazed at how much you learn this way.
