Basic Bath Bomb Recipe
Standard 6cm Bath Bomb
- 200g bicarbonate of soda
- 100g citric acid
- 100g cornstarch
- 2-3 tablespoons witch hazel
- 10-15 drops essential oil
- Food coloring (optional)
Makes 8-10 bath bombs.
Step-by-Step Process
#### Step 1: Mix Dry Ingredients
Combine baking soda, citric acid, and cornstarch in large bowl.
Whisk thoroughly. No lumps allowed.
#### Step 2: Add Colors and Oils
Add essential oil drops. Mix well.
Add food coloring if using. Mix until color spreads evenly.
#### Step 3: Add Liquid Slowly
Spray witch hazel while mixing constantly.
Add tiny amounts. Too much liquid causes early fizzing.
Mixture should hold together when squeezed but not be wet.
#### Step 4: Mold the Bombs
Pack mixture firmly into molds.
Press both halves together hard. Twist to ensure good seal.
#### Step 5: Dry and Unmold
Leave in molds for 2-3 hours.
Carefully remove. Let air dry for 24 hours.
Store in airtight containers to prevent moisture.
