Start by pouring the Epsom Salts into a mixing bowl.
Add the water, essential oil and food coloring, and stir. See this beautiful blue we're creating? I'm in love!
Grab your bath bomb mold and pack each of the sides with the salts. Make sure you pack it in firmly, putting in more salts than necessary.
Put the two mold halves together and press them together firmly over your mixing bowl (so you don't make a mess) for about 30 seconds or so. Brush away any salt granules that are around the outside of the mold.
Notes
Consistency Matters: Achieving the right consistency is crucial for bath bombs. Ensure the mixture holds together well when pressed into the molds. If it crumbles or falls apart easily, add a little more water, a few drops at a time, until you reach a texture that sticks together without being too wet.
Even Packing: When filling the bath bomb molds with the mixture, pack the salts evenly and firmly into each side of the mold. Overfilling slightly ensures a compact bath bomb that holds its shape well after it's removed from the mold. Press the two halves together firmly to create a seamless bath bomb.
Precision with Fragrance: Essential oils provide the scent for bath bombs. While peppermint is a popular choice, feel free to experiment with other fragrances to suit your preferences. Add the essential oil drop by drop, mixing thoroughly after each addition, until you achieve the desired strength of scent. Be cautious not to add too much, as it can overpower the bath bomb's fragrance and may irritate sensitive skin.
