Create Your Perfect Bath Bomb
Basic Bath Bomb Recipe
Fill your mold with our tried-and-true formula:
Essential Ingredients:
-
Sodium Bicarbonate (Baking Soda) - Creates the fizz
-
Citric Acid - Reacts with baking soda for bubbles
-
Corn Starch - Binds ingredients and slows fizzing
Typical Ratio:
- 2 parts Sodium Bicarbonate
- 1 part Citric Acid
- 1 part Corn Starch
This combination creates compact, long-lasting bath bombs that fizz beautifully and hold their shape.
Customize & Enhance
Add Your Signature Touch:
Fragrance:
- Essential oils for aromatherapy benefits
- Try lavender for relaxation, eucalyptus for clarity, citrus for energy
- Add just before molding for even distribution
- Larger size allows for more complex scent blending
Color:
- Mica powder for subtle shimmer
- Liquid or powder colorants for vibrant hues
- Natural colorants like beetroot or turmeric
- Create multi-colored layers or swirls
- More space for dramatic color effects
Special Effects:
-
Colored embeds - Hide small colored bath bombs inside for a surprise reveal
-
Multiple embeds - Larger size allows for several surprises throughout
-
Botanicals - Add dried flowers, lavender buds, or rose petals
-
Moisturizers - Include coconut oil, shea butter, or sweet almond oil
-
Salts - Epsom salt for muscle relief
Create Surprise Bath Bombs: Try adding colored embeds to the center of your bath bomb for an exciting surprise when it dissolves. As the outer layer fizzes away, a different colored core is revealed—delightful for kids and adults alike! The larger 7.8cm size gives you more room for multiple surprises and creative layers.
How to Use Your Mold
Step-by-Step:
- Prepare Your Mixture
- Mix dry ingredients thoroughly
- Add oils, colors, and fragrances
- Mix until texture resembles damp sand
- Should hold together when squeezed
- Fill Both Halves
- Overfill each half of the mold generously
- Pack mixture firmly into each side
- Add embeds to center if desired
- Mound mixture slightly above the rim
- Press Together
- Align both halves carefully
- Press firmly together with even pressure
- Hold for 10-15 seconds
- You should feel the mixture compress
- Release Your Bath Bomb
- Gently tap the mold on counter
- Carefully remove one half
- Tap lightly to release bath bomb
- Allow to dry for 24-48 hours before use
Pro Tip: The key to successful bath bombs is moisture content. Too dry and they won't stick together; too wet and they'll fizz prematurely. Aim for "damp sand" texture that holds its shape when squeezed.
