For a 500g soap bar mold:

• 290g clear melt & pour soap base
• 280g white melt & pour soap base
• Aqua mica powder
• Black mica or charcoal powder
• Gold mica powder (optional)

Step‑by‑Step Guide

1. Make the aqua base
   • Melt 240g clear and 30g white soap bases together.
   • Dissolve 2 tiny spoons of aqua mica in rubbing alcohol and stir it in.
   • Add 7 drops lemongrass essential oil.
2. Create the first embeds
   • Pour the aqua soap into the mold and let it set.
   • Remove it and cut it into angled pieces.
   • Dust the pieces with gold mica powder (optional — it can look nicer without).
3. Build the aqua layer
   • Place the chopped aqua pieces back into the mold along with a few thin white strips.
   • Melt and pour the remaining aqua soap over them.
   • If you don’t have enough, mix 1 part white : 2 parts clear soap base with 1 tiny spoon aqua mica to make more.
   • Set the mold on an angle and let it begin to firm up.
   • As it sets, use a spoon to create a bumpy surface.
4. Add the black layer
   • Melt 50g clear soap base and mix in black mica or charcoal dissolved in rubbing alcohol.
   • Pour this black soap over the aqua layer, letting it cover unevenly.
   • Create bumps again as it cools.
5. Prepare the white embeds
   • Chop 250g white soap base into angled pieces.
   • Dust some of them with black mica or charcoal powder.
6. Finish the white layer
   • Add the black-coated white pieces into the mold on top of the black layer.
   • Melt and pour the remaining white soap base over everything.
7. Set and slice
   • Let the entire block set completely.
   • Remove from the mold and slice into bars.
