Have you ever made your own soap? A few years ago I tried out soap making for the first time and had some very interesting experiences.
I did a lot of experimenting using bars of soap and made some really great things. I also blew up the microwave and had a bowl which stunk of soap forever more.
My skills are now refined and today we are sharing a fun DIY Mermaid soap tutorial.
Enjoy.

🎨 Supplies Needed
- 1-2 lb clear glycerin soap block
- 4-5 drops of essential oil
- Mermaid figures
- Square soap molds
🖌️ How To Make Mermaid Soap
- Step 1: Cut the glycerin into small chunks using a sharp knife and place in a 2 cup microwave safe glass measuring cup. Microwave the glycerin in 1-minute increments, stirring until completely melted.
- Step 2: If using essential oil, add 4-5 drops and stir. Fill each square soap mold ½ way with melted glycerin. Let sit for 20 minutes.
- Step 3: Place the mermaid figures face down in the soap molds on top of the set glycerin.
- Step 4: Fill with remaining glycerin. (You may need to re-melt in the microwave) Let the soap set for at least 1 hour.
- Step 5: Gently pop out of the molds. Your soap is now ready to use!
💡 Pro Tip: After unmolding, place soaps on a rack for two days to firm edges and let excess moisture evaporate, boosting durability and preventing sweating.
🧑🎨 Expert Tips
- Measure Precisely: Always weigh your soap base and additives on a digital scale and use calibrated spoons for mica or fragrance—this ensures uniform batches and prevents overly soft bars.
- Mold Preparation: Mist the mermaid mold interior with isopropyl alcohol and rub coconut oil into creases so each curve unmolds cleanly without sticking.
- Temperature Control: Cool your soap base to about 120°F before adding color and scent—this prevents burnout, preserves mica vibrancy, and avoids air bubbles.
- Layer Pouring: Pour base colors in stages, letting each layer firm slightly before the next—this keeps distinct bands and prevents unintended color blending.
- Embed Techniques: Wait until the top layer thickens enough to support glitter or shell embeds, then press pieces in gently without sinking or tilting.
- Cure Timing: Let soaps set at least 24 hours before demolding and 48 hours before use—this ensures hardness, lasting lather, and reduces surface tackiness.
