The ombré trend is popular for good reason. It’s timeless, a show stopper and looks so effortless, especially as a soap design. It is also a good way to see your colorant in action. I know I am not the only one that wonders how my new mica will look in cold process soap. Sometimes it’s a mystery that just needs to be solved. This technique allows to you see how subtle your mica mixture can be, to full on intense.

Additional Ingredients Used
PREP WORK: Slowly and carefully add the lye to the water and gently stir until the lye has completely dissolved and your solution is clear. Weigh out your soaping oils and set aside. I like to do these steps first to allow time for my lye solution and oils to cool down. (I recommend soaping around room temperature – 100° F).
Once your lye solution has cooled, add 2 teaspoons of Sodium Lactate and stir to dissolve. Sodium Lactate is a liquid solution that helps produce a harder bar of cold process soap and aids in the unmolding process. It should be used at a usage rate of 1 teaspoon per pound of oils.
To premix your colorants, use 1 tablespoon of a light liquid oil like sweet almond oil or apricot oil per 1 teaspoon of mica. You can also used 1 tablespoon of your batch oils, if you prefer. For this recipe, mix the activated charcoal and Black Knight Mica with 2 tablespoons of oil, 1⁄2 teaspoon of Titanium Dioxide with 1 tablespoon Distilled Water.
Measure out your fragrance. I like to incorporate the kaolin clay with my fragrance oil to help anchor the scent and to add slip to my soaps.
GET STARTED: To make even layers for the ombré design, you will need a measuring cup or beaker so you can pour the same amount of batter for each layer. Set this aside and place your stick blender into the cooled oils and burp it to release any air bubbles. Slowly add your lye solution to your oils and stick blend until emulsified.
Once emulsified, add the coconut milk into the batter and pulse to just combined. Then hand stir in the fragrance oil. You will want to work with a thin batter and let it naturally reach a thicker trace as you work. Do not use a stick blender to incorporate your fragrance oil, you may run the risk of thickening your batter too much where it will be difficult to work with near the end of the ombré .
POUR IT / SWIRL IT: Add the water dispersed titanium dioxide mixture to the entire batter to brighten it up a bit, you can skip this step if you would like to work your natural batter color.
After this step, pour a small portion of your batter into your measuring cup (remember this amount because you will use this same amount for each layer).
To begin pouring your batter, you will be using the wall pour technique. Place your spatula against one side of the mold and slowly pour the batter on top of it as you move your spatula against the side of the mold. Do this until your measuring cup is empty of raw soap.
Next, add 1⁄2 tsp of your mica at a time into the batter for each layer and mix until combined.
Repeat the coloring and pouring process against the side of the mold until all your raw soap has been used. By doing this, you will be building up the intensity of the ombré soap colors from lightest to darkest.
FINISHING UP: After tapping down your mold to release any trapped air bubbles, finish off the top any way you please. I like to keep it simple to really let your ombre design be the show stopper!
Spritz the top with isopropyl alcohol to help avoid soda ash and insulate for 24 hours. Carefully remove from the mold and cut into bars allowing the soap to cure for 4-6 weeks.
