Bath Bomb Recipe
1 cup baking soda
1/2 cup citric acid
1/2 cup epson salts (adds to the fizzing action)
1 to 2 teaspoons Fragrance Oil (optional)
2 1/2 Tbsp sunflower oil or Almond oil
Mix equal parts of water and glycerine. You will need approximately 3/4 teaspoons of this mixture.
1/4 teaspoon borax (an emulsifier) add Colorant (optional)
Step One Put all dry ingredients in a large mixing bowl. Mix together making sure the citric acid is thoroughly dispersed throughout. You'll want the citric acid and epsom salts to be in a granulated form. If you find they are too chunky, place them in a small coffee grinder to get a finer grade.
Step Two Combine oil, water/glycerin, fragrance, borax, and colorant in a separate bowl and mix well..
Step Three Slowly drizzle the oil/water/glycerin mixture into the dry ingredients. You DON'T want the mixture to fizz as you drizzle, so take your time. Don't drizzle the wet ingredients too fast, but be sure to miix the dry and wet ingredients thoroughly..
Step Four Once mixed, pack the mixture into each 3-D mold half. It's OK to overfill each half. You want the mixture to have the texture of slightly moist wet sand. The mixture should hold together when squeezed in the palm of your hand..
Step Five Refrain from twisting the two filled halves. Instead, firmly push the two halves together. Remove any excess mixture from outside of mold with your fingers or by wiping the perimeter with a paper towel..
Step Six You will want to unmold 1/2 at a time by gently tapping the first half of the mold a few time with your fingers. Let the bath bomb fall out of the mold one half at a time. Do not use forced or twist. Should the bath bomb crumble upon removal, do NOT discard. Instead, add a small amount of oil (1/8 to 1/4 teaspoon) and reshape the mixture into the mold..
Step Seven Once removing from molds, allow bath bombs to air dry undisturbed for 3 days on a clean kitchen dish towel or on waxed paper.
