I wonder what is the problem if soap cracks on the edges, some of our batches have some cracks and chips on the edges!

Thanks

That would be my guess to. It is sometimes called "volcanoing." If you used milks, honey, sugar, or just insulated it too long....volcano = cracking.

Getting to hot?
In the Mold or in the Pot?
We think the soap in the mold was about 110f when we poured it in.

Thanks

It can be a combination of too much heat in the mold & your recipe. I have a recipe that cracks no matter what. However, now I elevate my mold on a wire rack so air can circulate all around it. I also don't cover my mold at all.

That recipe now only has a fine hairline crack that closes as the soap cools down, but it always cracks, so I think it's the recipe.

The other recipes aren't cracking at all.

If you're using a TOG mold that comes with a liner, you'll find it insulates like crazy!! :lol:
