ONE: Combine the 16 oz of citric acid and 32 oz baking soda in a large bowl and mix well. Use your fingers to break up any clumps.
TWO: Once the mixture is smooth, add a heaping scoop of the red mica and mix well until you have a soft pink color. Again, you can use your hands if you prefer.
THREE: Once the color is mixed in, add your fragrance oil.
Tip: Make sure there are no clumps in your mixture. Clumps can result in wart like protrusions on your bath fizzy. Not attractive.
FOUR: Spritz with witch hazel until the mixture seems like it is staying together when you squeeze a handful in the palm of your hands (about 5 or 6 spritzes). Is it saying together? Then you’re ready for the mold.
FIVE: Fill each half of the mondo mold and pack the mixture as tight as you can. Then sprinkle on a little extra and place the second half of the mold on top. Squeeze the two halves together as hard as you can. If they are not packed hard enough, they could crack when drying. Trust me, it’s very disappointing.
SIX: Let the mixture rest in the mold for about 30 seconds then carefully slide it out of the mold onto a flat surface. Let it dry, undisturbed. You’ll be tempted to poke it, hold it or move it. Please don’t mess with it until it’s fully hardened, you’ll thank me later. This recipe yields 5 bath bombs.
