Instructions:
I used basic glycerin melt and pour soap bases for my DIY rainbow soap favors as this base tends to set up a LOT more quickly than the natural soap bases reducing the time spent waiting on the soap to set up. You can use a natural soap base however for the very last step, with the final blue layer around the white cloud, I recommend a basic base.
If you’d like to scent your DIY rainbow soap favors, use the recommended amount for your fragrance oil of choice at each step. Avoid using a fragrance oil with vanilla as it will turn your soap brown over time. You should also avoid fragrances with a yellow tint as it will affect the color of your soap – ie. your white cloud may become a yellow-ish one.
You’ll start by making the rainbows for this soap project. Begin by placing the rectangular soap mold onto a cutting board for easy transport.
Weigh out .65 oz. of your clear melt and pour soap base. Place the soap in a small Pyrex measuring cup. Heat the soap for about 15 seconds in the microwave, just until soap has melted. Don’t allow the soap to boil. Add 4 drops of the Stained Glass Santa Red Soap Color. Stir, then pour the soap into one cavity of the Ozera soap mold.
Spritz the top of the soap with alcohol to remove any air bubbles.
Place in the refrigerator until the soap has solidified.
Once the soap solidifies you’re ready for the next layer.
Starting with a freshly washed glass Pyrex measuring cup, weigh out .7 oz. of the clear melt and pour soap base. Heat to melt then add 5 drops of the Stained Glass Citrus Orange Soap Color. Stir to combine.
Spritz the top of the previously poured layer of red soap with alcohol, then pour the orange tinted soap on top of the red soap layer. Spritz with alcohol again to remove any soap bubbles.
Refrigerate the soap until the orange layer solidifies.
Repeat the previous steps using .65 oz. of clear melt and pour soap and 7 drops of Stained Glass Lemon Yellow Soap Color.
On top of the yellow layer, add .7 oz. clear melt and pour soap with 4 drops of Stained Glass Forest Green Soap Color.
Follow the green soap layer with .7 oz. of clear melt and pour soap and 4 drops of Stained Glass Ocean Blue Soap Color.
Follow the blue soap layer with .7 oz. of clear melt and pour soap and 3 drops of Stained Glass Violet Soap Color.
Finally, add .7 oz. of clear melt and pour with 7 drops of the Stained Glass Violet Soap Color – or purple if you have it – as the final layer in your rainbow soap.
Once your rainbow soap bar has fully solidified, carefully remove it from the mold.
Using a Chef’s knife, cut the bar of rainbow soap into six equally sized strips.
Set your rainbow soap slices aside.
You’re now ready to make the cloud base for your DIY rainbow soap favors. Place the guest round soap mold on a cutting board for easy transport.
Now weigh out 2.5 oz. of the white melt and pour soap base into a glass Pyrex measuring cup. Heat the soap in the microwave until melted.
Pour the white melt and pour soap base equally into each of the mold’s cavities, about 1/3rd of the way full.
Place the mold in the refrigerator, using the cutting board for support, until the soap hardens.
Now remove the soap from the fridge. Spritz the tops of the solidified white melt and pour soap with alcohol.
Gently curve six of the rainbow strips into rainbow shapes and place one rainbow into each of the guest soap mold’s cavities.
Weigh out 5 oz. of white melt and pour soap base. Cut into chunks and place inside the glass Pyrex measuring cup.
Melt the soap in the microwave in 30 second increments until melted.
Spritz the tops of the white soap base in the mold, then carefully fill all six of the mold’s cavities with the melted soap around the rainbows. Allow the soap to harden in the fridge.
Once your DIY rainbow soap favors have hardened, carefully remove them from the mold.
Now melt 4 oz. of white melt and pour soap base in a shallow glass bowl. Add the teal mica powder to the melted base to suit and mix well to combine.
Allow the blue tinted soap to cool slightly, then dip the base of each of the rainbow soaps into the soap. Allow the soap to cool further then dip the soap into the blue soap again.
Place the rainbow soaps on parchment or wax paper in between dipping them in the blue soap. Allow them to harden after each dip in the “blue sky” before dipping again.
As the blue soap hardens around the white base of the rainbow soaps, you can fold the soap over or add clumps of half hardened blue soap. Then simply re-heat the blue soap again if needed and dip the rainbow soap bases into the blue melted soap again to smooth out the edges of the soap for a smooth finish.
Once you’ve reached your desired look, simply allow the soaps to finish solidifying. Then package your melt and pour DIY rainbow soap favors as desired for gifts or party favors.
If you are making my DIY rainbow soap favors to sell, you’ll need to label your soaps appropriately to meet state and federal laws. If you’re unsure about the rules and regulations regarding labeling cosmetics, I highly recommend the book, Soap and Cosmetic Labeling: How to Follow the Rules and Regs Explained in Plain English, by Marie Gale.
