Create Surprise Bath Bombs: Add a small colored natural embed to the center for an exciting reveal—delightful for children and adults, using only ingredients you've chosen yourself. How to Use Your Mold Step-by-Step:
  1. Prepare Your Natural Mixture
  • Mix dry ingredients thoroughly
  • Add oils, natural colors, and essential oils
  • Mix until texture resembles damp sand
  • Should hold together when squeezed
  1. Fill Both Halves
  • Overfill each half of the mold generously
  • Pack mixture firmly into each side
  • Add natural embed to center if desired
  • Mound mixture slightly above the rim
  1. Press Together
  • Align both halves carefully
  • Press firmly together with even pressure
  • Hold for 10-15 seconds
  • You should feel the mixture compress
  1. Release Your Bath Bomb
  • Gently tap the mold on counter
  • Carefully remove one half
  • Tap lightly to release bath bomb
  • Allow to dry naturally for 24-48 hours before use
Natural Approach: The key to successful bath bombs is moisture content. Too dry and they won't bind; too wet and they'll fizz prematurely. Aim for "damp sand" texture that holds its shape when squeezed—no chemical binders needed. Easy Care & Maintenance Sustainable Cleaning After Each Use:
  • Rinse with warm water immediately
  • Wash with natural soap and hot water
  • Dry thoroughly with clean towel
  • Ensure completely dry before storing
Deep Cleaning:
  • Use Isopropyl alcohol for thorough sanitization

  • Great for removing oil residue
  • Keeps mold fresh and ready for next use
Storage:
  • Store in cool, dry place
  • Keep away from moisture
  • Ensure completely dry before storing
  • Stack carefully if storing multiple molds
