Ingredients
  • 48 oz. Grated Luxury Rebatch Soap
  • 3-4 oz. Distilled Water
  • 2 Tbsp. Activated Charcoal
  • 1.2 oz. Sandalwood Vanilla Fragrance Oil
  • Snowflake Sparkle Mica
Instructions
  1. Place the Luxury Rebatch Soap into your Crock-Pot, double boiler, or fondue pot. If using a Crock-Pot or fondue pot, turn the temperature on low and add about 1 ounce of water. Allow the soap to “cook” for a few minutes to gauge the temperature. If you see the soap starting to melt slightly, you can increase the temperature to low-medium and stir frequently.
  2. As the soap cooks, add small splashes of water to help it melt down smoothly. Continue stirring frequently so the soap at the bottom of the pot doesn’t burn. After a few minutes, the soap will look like very thick mashed potatoes, as shown below. Continue cooking slightly past this point to melt down any pieces of soap still present. Add a bit more water if necessary.
  3. Once the soap is smooth, add 1.2 oz. Sandalwood Vanilla Fragrance Oil and thoroughly mix in for several minutes.
  4. Add the activated charcoal 1 teaspoon at a time. Stir thoroughly between each addition.
  5. Once all the charcoal is added, the soap will have a gray color. If it’s still very thick, add small amounts of water to achieve a smoother consistency. We don’t recommend adding more than 4 ounces of water. If you still see large chunks of rebatch, let the soap continue to cook for several minutes. Turn up the heat if necessary, just be careful to not let the soap burn!
  6. Lay down several pieces of wax or parchment paper down on your work surface. Then spoon dollops of soap onto the paper. You can make them whatever size you like. Our soaps weighed about 2-3 ounces each.
  7. Sprinkle Snowflake Sparkle Mica and a touch of activated charcoal onto each soap. Use your hands to press the colors into the soap. There is really no right or wrong way to do it, and don’t worry about making them perfect. If the soap is still too warm and not holding its shape, allow it to cool for a few more minutes.
  8. Allow the soap to fully cool and harden on the paper for a few hours. Once they are completely firm, transfer them to an area where they can cure for at least a week. Rebatch soap is ready to use once it’s cool, but we find letting it cure for at least a week allows any excess water to evaporate and creates a longer-lasting bar. Enjoy. NOTE: These bars do lather gray due to the charcoal content.
