  1. Add Epsom salt to a small bowl and add 1/2 teaspoon of mica powder and stir until mixed well. Set aside 1 teaspoon of the colored Epsom salt.

  2. Combine baking soda, remaining Epsom salt, citric acid, and cornstarch in a medium bowl. Add in essential oils and coconut oil. Slowly add in water and mix until consistency is similar to wet sand and the mixture starts to stick together.

  3. Add a small amount of the reserved colored Epsom salt to the bottom of a bath bomb.

  4. Pack each half of the bath bombs with mixture, slightly over-filling. Firmly press halves together. Set mold aside for at least 15 minutes, and up to 2 hours.

  5. When ready to remove the bath bombs, gently tap the sides of the mold with a spoon, then remove mold.

  6. Allow bath bombs to set for 24 hours before using. Bath bombs can be stored in a container, away from water, for up to 6 months.
