How To Fix Cracking Bath Bombs
Adjust Moisture Content
If the bath bomb cracked simply to a moisture issue you can let them completely dry, break them apart, adjust the moisture content in the recipe and try to re-mold the bath bombs.
If you were using hard plastic or metal mold then try using a silicon mold next time. They have a little more give and can be more forgiving when it comes to bath bomb expansion and causing cracks.
Adjust Your Recipe
If bath bombs keep cracking it might be necessary to adjust your recipe. There are a few things you can try such as adding more baking soda or citric acid. You can also try using witch hazel, a different oil or butter in the recipe.
If your bath bombs crack because they are getting too dry then a little bit of extra oil content will help keep the mixture a bit more stable while it hardens in to the mold.
Preventing Bath Bombs From Cracking
Now that we know how to fix bath bombs if they crack, let’s take a look at how to prevent bath bombs from cracking in the first place.
Use The Right Mold
As we mentioned above, bath bombs can crack if they are made in the wrong mold. It is best to use a silicon mold as they are more forgiving. Hard plastic and metal molds can cause bath bombs to crack.
Adjust Moisture Content
Another thing you can do to prevent bath bombs from cracking is to make sure the moisture content in your recipe is correct. If bath bombs are too dry they will crack, if bath bombs are too wet they will also crack.
Getting the moisture content just right can be a bit of trial and error but once you find the perfect mixture, bath bombs should not crack.
Pack The Mixture Tight
When packing bath bomb mixture in to the mold it is important to pack it tight. This will help prevent air pockets from forming which can cause bath bombs to crack.
Pack the bath bomb mixture in to the mold and then use your fingers or a spoon to press it down tight. Make sure the bath bomb mixture is evenly distributed in the mold so it hardens evenly.
Let Them Dry Completely
Once bath bombs are in the mold it is important to let them dry completely before removing them. If bath bombs are removed from the mold too soon they can crack.
Bath bombs need to harden completely before they are removed from the mold. The bath bomb will feel firm to the touch and will not leave an imprint if you press on it gently.
Bath Bomb Troubleshooting Tips

Make sure you are using fresh, quality ingredients. Baking soda and citric acid can lose their potency over time.
Check that you are measuring the ingredients correctly. Too much or too little of an ingredient can affect the fizzing reaction.
Try changing the ratio of baking soda to citric acid. A 1:1 ratio is typically used but a 2:1 ratio of baking soda to citric acid can also be used.
Add a little bit of extra oil to the recipe. This will help bath bombs hold together better and prevent them from cracking.
Add a small amount of witch hazel to the recipe. This can help bath bombs hold together better and prevent them from cracking.
