Slowly and carefully add the lye to the water and gently stir until the lye has fully dissolved and the liquid is clear. Set aside to cool.
Melt and combine the coconut oil, olive oil, castor, sweet almond and palm oils (remember to fully melt 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 water to the oils and stick blend until 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 1 teaspoon sodium lactate.
Once the batter has reached a thin trace, split off about 200 mL of the soap into a separate container. To this container, add 1 Tablespoon of the dispersed titanium dioxide and mix together with a whisk or spoon.
To the other larger container of soap, add all the dispersed rose clay and mix together thoroughly with a spoon or whisk.
Add the Hungarian Lavender Essential Oil to both containers proportionately; it’s okay to eyeball it! Use a whisk to thoroughly mix in the essential oil.
Add 2 cups of the pink sea salt to the rose clay soap, and mix in with a whisk or spatula.
Holding the white soap about six inches above the pot of rose clay soap, pour the white soap into various areas of bowl. Pouring from high above the bowl allows the white soap to break through to the bottom of the rose clay soap.
Using a spoon, chopstick or dowel, give the soap one stir to help swirl the colors slightly. Don’t stir too much, you don’t wan to completely mix them!
Pour the soap into each heart cavity in all three molds until completely full. You’ll have nine bars total. Tap the mold on the counter to release bubbles and settle soap evenly in the mold.
Spritz the top with 99% isopropyl alcohol to help avoid soda ash. Allow the soap to harden in the mold for 2-3 days. Allow to cure for 4-6 weeks and enjoy!
