Slowly and carefully add the 3.2 ounces of lye to the 7.3 ounces of distilled water and gently stir until the lye has fully dissolved and the liquid is clear. Set aside to cool. Once cooled to about 130° F , add 0.7 ounces of sodium lactate to the lye water. Sodium lactate is used in hot process at 3% of the oil weight to help produce a smoother bar.
Fully melt the entire bag of Lots of Lather Quick Mix until it’s completely clear and there’s no cloudiness. Shake the bag to mix up all the oils. Measure 22 ounces into your Crock-Pot and turn it on. NOTE: The heat setting you use may vary depending on your cooking vessel. We’ve cooked hot process soap on low and high heat with equally good results. For this recipe, we used the high heat setting for a faster cook time. If you’re making hot process soap in your cooking vessel for the first time, start with the low setting. Next time try the high setting and see which you prefer.
Slowly add the lye water to the oils. Make sure the mixture does not fill up more than half of the pot or cooking vessel. Tap the stick blender on the bottom of the pot to release air bubbles and begin to blend.
Mix with the stick blender until a thick trace is achieved.
Put the lid on the Crock-Pot and allow the soap to start cooking. After about 10 minutes, check the soap. Starting from the outside, the texture and color of the soap will start to change into a glossy, slightly Vaseline-like texture. Stir the soap to ensure even cooking. Place the lid back on and allow it to cook for another 5-7 minutes. NOTE: Don’t be surprised if the soap starts to grow in volume. Don’t leave your soap unattended in the first 10 minutes of cook time for this reason. If the soap gets too high in the pot, wearing gloves, take the pot off heat and stir like crazy.
The batch is ready when it’s the texture of glossy mashed potatoes. This may take up to three more 5-10 minute sessions, depending on how hot your Crock-Pot is. When you think it’s ready, use a pH strip to test the levels. Place a small amount of the soap into a cup of distilled water and stir. Dip the pH strip into the water – it should be below 10. Be sure not to overcook the soap, you don’t want it too dry for the next steps.
Add 1/2 teaspoon of dispersed Ultramarine Blue Pigment directly to the soap and stir until it’s fully combined.
Add all of the 1.3 ounces of Blueberry Thyme Fragrance Oil and stir to fully combine.
Working quickly, spoon the soap into the mold. Tap the mold on the counter firmly to help it settle. Once all the soap is in the mold, use a spoon or gloved hands to smooth the top.
Insert the blueberry embeds into the soap. We used 6 embeds, which created nice thick bars. Depending on how many embeds you make, you can place them closer together to create smaller bars.
Working very quickly, sprinkle poppy seeds on top and use your hands to press them into the soap. Sprinkle on more than you want, because some will fall off when the bars are cut.
Allow the soap to stay in the mold for at least 24 hours. Unmold and cut into bars. This soap is ready to use right away, but will last longer in the shower after at least a 2 week cure time.
