I'm fairly new at making bath bombs. My first batch turned out great, but since then I've had issues. Now my bombs are hard, but flakey. What is the issue? Do they need more liquid?
Have you been sifting the ingredients? Sometimes clumps cause this. Maybe warmer temperatures in your environment, too.
We have to remember that just a small difference in any of these ingredients can make a difference in the outcome of our bath bombs. I always recommend to try and set up all ingredients before starting the mix/process. Also, try to do this when you are in no hurry and have no distractions (turn your cell phone off?).
I thought they were supposed to be hard and flaky, all the ones I have bought have been.
Do they not dissolve when put into the tub? If they do, I would not worry about it. If they don't dissolve then possibly more moisture.
You probably need more witch hazel or oil.
