Ingredients
  

DIY Aroma Stones
  • 1/2 cup baking soda our base, making the stones firm
  • 1/2 cup cornstarch helps create that smooth, moldable texture
  • 1/4 cup warm water just enough to bring everything together
  • 15–30 drops essential oil Choose your favorite scents like calming lavender, uplifting lemon, refreshing peppermint, or invigorating eucalyptus.
  • Optional Natural colouring (mica powder or food colouring) For a pretty pop of color to match your decor or mood.

Equipment

  • Mixing bowl
  • Spoon
  • Silicone moulds, cookie cutters, or ice cube trays
  • Parchment paper or drying tray

Method
 

  1. In your mixing bowl, combine the baking soda and cornstarch. Give them a good whisk or stir to make sure they're well mixed.
  2. Now, slowly start stirring in the warm water, a little bit at a time. Keep mixing until you have a nice, thick, clay-like dough. You want it to hold its shape.
  3. If your mixture feels a bit too sticky (it happens!), just add a tiny bit more cornstarch, a teaspoon at a time, until it's just right – not too wet, not too dry.
  4. If you're adding color, this is the time! Mix in your natural coloring until the dough is evenly tinted. I love using mica powders for a subtle shimmer, but food coloring works great too for bolder hues.
  5. Now for the fun part: pressing! Gently press the dough into your silicone moulds. If you're using cookie cutters, roll out the dough on a clean surface to about 1/4 inch thick and press your shapes out.
  6. Smooth any rough edges with your fingers. This makes them look extra polished, almost like little pieces of art.
  7. Carefully pop the shaped stones out of their moulds (or lift them off your rolling surface) and place them onto parchment paper on a tray to dry.
  8. Now, patience is key! Let the stones air-dry completely. This usually takes about 24–48 hours. They should feel totally hard to the touch.
  9. To ensure they dry evenly on all sides, go ahead and flip them over halfway through the drying process.
  10. Once your aroma stones are bone dry and hard, it's time to add the scent! Drizzle about 3–5 drops of your chosen essential oil onto each stone.
  11. Give them a little time to soak up all that lovely fragrance – about 1–2 hours is perfect. Then, you can display them in your favorite spots!

Notes

Keep them in a cool, dry place away from direct sunlight. They'll retain their scent for quite a while, and when the scent starts to fade, you can simply add a few more drops of essential oil to refresh them. They can last for several months, sometimes even longer!
