This Mason Jar Bath Bomb tutorial is so easy to make and perfect for gift-giving. Whether you are making this bath bomb for yourself or someone else on Mother’s Day, you will love the pleasant aromas and colors these homemade bath bombs have to offer. If you like Lush bath bombs, then you’re going to love making this bath bomb at home.
If you happen to be like me and have a plethora of mason jars, then you probably are in need of some extra crafts. Be sure to check out my Fairy House Mason Jar to create your own mystical world!
I am dividing this tutorial up into two parts. First, we will make the mold.

For the Mold
- ComposiMold (I will walk a bit more about this product below)
- 4 oz mini Ball jar
- Vaseline or other mold release material
For the Bath Bomb
- Epsom salt
- Corn starch
- Baking soda
- Citric acid (I bought mine from Amazon here)
- Lavender essential oil (or another scent) (see this post on how to buy these oils)
- Blue food coloring
ComposiMold is new to me but it is absolutely perfect for this project. You melt it in the microwave, insert the item to be molded, then allow it to cool. Composimold takes the shape of whatever you have added and it can be used just like a mold. The best part about this product is it is re-usable! Just melt it back down and create another mold. This product is perfect for someone like me who only wants to use a mold once or twice and then move onto another project.
First, I started by melting the product in the microwave. Then, I applied Vaseline to my jar as a mold release agent then added the jar to the product. If you happen to have some popsicle sticks and hot glue, then you can make a rig to hold the jar into place while the product cooled. The most difficult part about this mason jar mold was unmolding the jar from the product as shown below. Please remember to follow all instructions on the packaging of the ComposiMold for the best results.
You can watch me make these bath bombs in the video below. The 1/2 cup of each of the ingredients was just about perfect for three bath bombs.
How to Make Your Mason Jar Bath Bomb
MIX DRY INGREDIENTS: First, mix the Epsom salt, citric acid, corn starch, and baking soda together.
ADD ESSENTIAL OIL: Next, add the essential oil to the Epsom salt mix.
ADD WATER: Place a little bit of water into the salt mix.
ADD FOOD COLORING: Add food coloring into the mixture until you reach the desired shade of color.
PACK THE MIXTURE: After that, pack the bath bomb mixture into the mold you created. Press very well.
CHILL: Finally, refrigerate for one hour.
REMOVE & DRY: Remove the solidified bath bomb from the mold. Allow it to air dry for a day or two before packaging.
Bath Bomb in a Bag
First, cut the tags out with scissors and add a hole with a hole punch.
Next, add the bath bomb to a plain plastic bag. I used treat bags from the party section. Tie on the tag with a ribbon.
You can now give a mason jar bath bomb to anyone on your gift-giving list. Gift this mason jar bath bomb to all your loved ones!
How to Use This Mason Jar Bath Bomb
In warm water in the bathtub, unpackaged the bath bomb and place it in the water. The bath bomb will slowly dissolve and release the aromas you added. You will witness a science experiment right before your eyes!
