  • 6 Bar Oval Silicone Mold
  • 29 oz. Clear Melt & Pour Soap Base
  • 2 Wool Sea Sponges
  • Jagua Blue Extract
  • 0.6 oz. Midnight Waters Fragrance Oil
  • 0.6 oz. Vanilla Color Stabilizer
  • 99% Isopropyl Alcohol in a Spray Bottle
SEA SPONGE PREP: Cut the wool sea sponges into about 3-4 pieces. We cut them into 3 pieces, but you can make them smaller or larger if you want.
  1. Chop 29 ounces of Clear Melt and Pour Soap Base into small, uniform cubes. Place them into a heat-safe container and melt in the microwave using 30-60 second bursts. Stir between each burst.
  2. While the soap is melting, mix together 1/16th teaspoon of jagua blue extract and 2 teaspoons of 99% isopropyl alcohol. Mixing the jagua blue extract with alcohol helps prevent clumps.
  3. Once the soap is melted, pour all of the dispersed jagua blue extract into the soap and stir until completely incorporated.
  4. Add 0.6 ounces of Midnight Waters Fragrance Oil and 0.6 ounces of Vanilla Color Stabilizer. Mix together.
  5. Fill each cavity of the mold about 80% full. Spritz the top with alcohol to help get rid of bubbles. Allow this layer of soap to harden and cool for about 15-20 minutes. The soap needs to build a strong enough skin to support the sea sponge.
  6. Once the soap has slightly hardened and formed a strong skin on top, reheat the remaining soap using 15 second bursts. Spritz all the cavities with 99% isopropyl alcohol to help the layers stick together.
  7. Fill the cavity with melted soap. Once full, place the sea sponges into the soap. Spritz the soap with 99% isopropyl alcohol to get rid of any bubbles. Continue for each cavity.
  8. Allow the soap to fully cool and harden for several hours or up to overnight. Once fully cool, remove the soap from the mold and enjoy. To prevent glycerin dew, wrap the soaps in plastic wrap and store in a cool, dry place.
