Slowly and carefully add the lye to the black tea and gently stir until the lye has fully dissolved. The mixture will be a brown color. Do not panic. That’s what the titanium dioxide is for. Set aside to cool.
Fully melt the coconut oil, olive oil, cocoa butter, matcha green tea butter, sweet almond oil, and palm oil. Remember to fully melt and then mix your entire container of palm oil before portioning. Once the lye water and the oils have cooled to 130 degrees or below (and are ideally within 10 degrees of each other), add the lye to the oils and stick blend until you have a thin trace. If you’d like a harder bar of soap that releases faster from the mold, you can add sodium lactate to the cooled lye water. Use 1 teaspoon of sodium lactate per pound of oils in the recipe. For this recipe, you’d add about 3.5 tsp. of sodium lactate.
Once you reach a very thin trace, add all the Bergamot Black Tea Fragrance Oil. It’s okay to add the fragrance at the beginning because it behaves very well in soap.
Split off about 26 ounces of soap into a separate container. Add 2 teaspoons of dispersed activated charcoal, and use a whisk to fully mix in. Set aside.
Add all the dispersed titanium dioxide into the large amount of remaining soap. Use the stick blender to fully incorporate the titanium dioxide. Then split the batch in half. Each should weigh about 26 ounces. Add all the dispersed purple Brazilian clay to one container. Use the stick blender to incorporate the clay. Leave the other container of soap uncolored.
Now it’s time to start layering! First, make sure all the colors of soap are a medium to thick trace. Stick blend each from lightest to darkest until a medium to thick texture is achieved. Because they all have different amounts of various colorants, they may thicken at different rates.
Once you’re happy with the texture of each color, pour half of the uncolored soap into the mold and use a spoon to even it throughout the mold. Use the spoon to give the layer texture, because this design does not need exact straight layers.
Pour half of the black soap onto the white. Be careful not to let the black soap fall through the first layer of white. Use a spoon to gently cover the white soap. Use the spoon to spread it evenly, and to give it texture.
Cover the black soap with half of the purple soap. Again, use a spoon to spread it evenly and create texture. Tap the mold firmly on the counter to help evenly disperse the soap and get rid of bubbles.
Continue to layer the soap into the mold with the same color sequence: white soap, black soap, purple soap. Use up all of the remaining soap for the second layer.
Once the last of the purple soap is poured into the soap, use a spoon to mound the soap in the center and create peaks. There is no right or wrong way to do this, so just have fun with it!
Once you’re happy with the top, sprinkle the used black tea leaves down the center of the soap. Lightly press them (with gloves on) into the soap to help them stick once cut. Spritz the top with 99% isopropyl alcohol to prevent soda ash. Because this soap has a tendency to form glycerin rivers, keep it cool. Do not cover or insulate. If you live in a hot climate, consider placing the soap in the fridge or freezer for several hours to keep it cool. After about 2-3 days, unmold the soap and cut into bars. Allow to cure for 4-6 weeks. Because it does have a heavy water discount, 4 weeks should do the trick. Enjoy!
