This beautiful soap is super simple to make and uses an easy layering technique.

This recipe fits in a 10″ Silicone Loaf Mold from Nurture! (I made a half batch for this tutorial.)

SAFETY WARNING! Let’s make soap! If you are new to soapmaking, be sure to download our free guide, How to Make Cold Process Soap! Gear up in your gloves and your safety glasses.

Step 1: Make your lye solution. Weigh the water and lye into separate containers. Pour the lye into the water while stirring. Be sure to mix your lye solution in a well-ventilated area.

Step 2: Weigh out your solid/hard oils and melt.

Step 3: Weigh out your liquid oils and add to your melted oils. Add the essential oil blend to the base oils.

Blend to light trace.

Step 4: Divide your batter out. I used about 2/3 for the base and 1/3 for the top.

Step 5: Color your base using Caribbean blue mica. I used about 1/4 teaspoon. Add a little and then add a little more. The blue mica + yellow soap base creates a nice green. If you add too much, you’ll get blue.

Add 1/4 teaspoon ground dried mint leaves to the other portion. (If you want!)

Step 6: Using your stick blender, bring the green base to a thicker trace.

Step 7: Pour this into your mold.

Step 8: Create your charcoal line. I use a small tea strainer to dust the charcoal on. Don’t over do it! Don’t create a solid line or your soap layers will come apart.

Step 9: Pour on your top layer. If you brought the bottom layer to thick trace then it should hold the top layer well.

Pouring over a spatula will help to ensure that the soap doesn’t dive into the bottom layer.

Let your soap sit for 24 hours, unmold and cut your soap!

Cure your soap for 4 weeks!

Happy Soaping!
