Prep ahead: Weigh the essential oils into a glass container; blend together.
Step 1: Weigh the distilled water into your lye solution container.
Step 2: Weigh the sodium hydroxide into your dry lye container.
Step 3: Following safety precautions, pour the sodium hydroxide into the water while stirring. Turn your head and lean away from the lye solution. Stir until all the granules have dissolved. Set aside to cool.
Step 5: Weigh and melt the solid oils and butters.
Step 6: Weigh the liquid oils into the melted oils and butters.
Step 7: Add your essential oils to the prepared base oils and blend.
Step 8: Check the temperature of your base oil mixture and lye solution. For a layered soap, a good range for both mixtures is between 80°F and 90°F.
Step 9: Pour the lye solution into your melted oils and mix to light trace.
Step 10: Divide your soap into 3 equal parts to color.
Step 11: Add one of the three natural colorants to each container and blend well.
Step 12: Thicken up one of the colors and spoon half of it into your mold. Add a charcoal line by sprinkling a bit of charcoal over this poured layer.
Step 13: Thicken up the next color, and spoon half of it over your first layer.
Step 14: Thicken up the last color, and spoon half of it over your second layer.
Step 15: Repeat steps 12 to 14 a second time for a total of 6 layers in this soap.
Step 16: Allow the soap to saponify for 24 to 48 hours.
Step 17: Unmold your soap, cut into bars, and allow to cure in a cool, dry space for at least four weeks. Tip: If 6 layers is intimidating, feel free to only do 3 layers, using all of each color each time you pour.
