A calming craft project that combines shells, a crystal-forming solution, and time to create beautiful crystal shells.

Ingredients

  • Clean seashells (small to medium size)
  • Borax powder or alternative crystal-forming mineral
  • Warm water (nearly hot but safe to touch)
  • Glass jars or heatproof bowls for soaking
  • Measuring spoon and small measuring cup
  • Wooden or metal stirring spoon
  • Tweezers or small tongs (optional)
  • Paper towels and a tray to catch drips
  • Food coloring or a few drops of dye (optional)
  • A small funnel or dropper (optional)
  • A decorative display tray or shallow dish (optional)

Instructions

  1. Warm the water until it feels hot but safe for a finger test.
  2. Measure roughly three parts water to one part borax and stir until most dissolves.
  3. Pour the warm solution into a clear jar or bowl.
  4. If using food coloring, add one or two tiny drops and stir lightly.
  5. Nestle a shell into the solution with the opening facing up.
  6. Rest the jar on a flat surface and cover loosely with a breathable cloth.
  7. Check after one hour, and then every few hours for crystal growth.
  8. When crystals reach desired size, lift the shell and let excess solution drip back.
  9. Place the shell on a paper towel to dry slowly.
  10. If needed, rinse gently with cool water and pat dry.

Notes

Adjust soak time and concentration for different results. Each shell grows crystals uniquely, so invite curiosity in the process.
