Bring water in the bottom pot of a double boiler to a boil.

While the water is heating prepare the soap base by cutting it into small cubes.

Put the small cubes of soap base into the top pot on the double boiler and allow to melt completely. Stir frequently until all of the soap base is melted.

Once melted add 4 tsp of activated charcoal powder to the soap base.

Whisk charcoal and soap base together until fully combined.

Remove the charcoal and soap base from the double boiler and allow to cool briefly (1-2 minutes). Continue to stir.

Add the tea tree oil to the soap base and charcoal. Whisk to combine.

Pour the finished soap into the silicon molds. Distribute evenly.

Allow the soap molds to sit 3-4 hours untouched in a flat, dry space until fully hardened.
