In a small bowl, combine the almond oil and essential oils.
In a large bowl, mix the baking soda, citric acid, Epsom salt, and corn starch.
Slowly pour in the almond oil mixture, stirring as you go.
Spray with water gradually, just enough to make the mixture clump together like damp sand (I used around 6 sprays).
Separate into 2 bowls.
Add red mica powder and stir until you reach your desired shade.
Layer the white and red mixture one by one until it is full. Firmly press down.
Let sit for 24 hours, or until fully hardened. Then gently unmold.
To Use: Drop one into a warm bath and enjoy
