🔬 Instructions:

1. Create the mixture

In a mixing bowl, combine:

• ½ cup baking soda

• ¼ cup cornstarch

Mix the dry ingredients well to ensure even distribution.

2. Add water and heat

• Add ¼ cup of water to the dry mix and stir until smooth.

• Heat the mixture gently:

  • Stovetop: Pour into a non-stick saucepan and stir continuously over low heat.

  • Microwave: Heat in 15–30 second intervals, stirring between.

You’re aiming for a thick dough consistency — like playdough. It should pull away from the sides of the bowl or pan.

⚠️ Do not overcook, or the dough may dry out and become crumbly.

3. Cool the dough

• Let the dough cool slightly so it’s safe to handle.

• Once cool, knead briefly for a smooth texture.

4. Add essential oils and optional ingredients

• Add 10–20 drops of essential oil(s) and knead into the dough.

• Add colorants or dried botanicals if using.

📝 Tip: If you want to use multiple scents, divide the dough and add different oils to each portion.

5. Shape the stones

• Press the dough into silicone molds or shape small balls/discs by hand.

• You can also roll and cut out shapes using cookie cutters.

6. Dry completely

Let the stones dry:

• Air dry for 24–48 hours (preferred for even drying).

• Optional oven method: Bake at 150°F (65°C) for 1–2 hours, flipping halfway.

Fully dry stones will feel hard and chalky.

🧴 To Use:
