Intergalactic Planetary Melt and Pour Soap Tutorial

A great project for kids of all ages (and I’m totally counting myself in this ‘kid’ category), this theme will particularly appeal to those who enjoy their time with a sci-fi edge. Swirling multiple colors of melt and pour base into sphere molds creates a planetary feel while shimmery black mica paired with silver glitter sends the planets on an adventure through a star-filled sky.

Planetary Soap

FRAGRANCE OIL PREP: Blend the Blackberry Cybilla and Fresh Mango Fragrance Oils to create the custom Blackberry Mango fragrance blend. NOTE: Fresh Mango is definitely a more green-smelling mango, which I think balances out the super fruit notes of the blackberry. However, if you’d prefer a more fruity explosion of awesomeness, try out Mango Mango Fragrance Oil or even Mango Peach Salsa Fragrance Oil in your blend! We’ve got you covered on the mango front. =)

ONE: Cut 15 ounces of Clear Melt and Pour Base into 1-inch cubes and melt in a heat-safe container on 30 second bursts in the microwave. Repeat with the White Melt and Pour Base. Add 0.4 oz of the Blackberry Mango fragrance blend to the clear soap, and  3 mL of the Blackberry Mango fragrance blend to the white soap. Stir until well mixed.

TWO: Split the Clear Melt and Pour Base into 5 – 3 oz portions. Create your planetary colors using the color blocks. For my colors, I used the Chrome Green Color Block in one, the Ultramarine Blue in another, a combination of Ultraviolet Blue and Perfect Red to create a purplish-red in the third, Perfect Orange with just a hint of Shimmer Yellow in the fourth, and Shimmer Yellow on it’s own in the fifth. Remember that what you see is what you get (WYSIWYG), so have fun with blending color blocks for an out-of-this-world palette!

Color mixed in

NOTE: Is this your first time using color blocks? I use a Clean-up Tool to shred the blocks and mix those in. If you’re a visual person, check out his quick vid!

THREE: Once all of your 3 oz portions of soap (including both the colorful and the white portion) are around 130 degrees Fahrenheit, start filling your spheres. There isn’t enough soap to fill each cavity of each sphere mold; what I did was filled one cavity of the 4 sphere mold, 6 cavities of the Large 9 Ball Silicone Mold, and all of the cavities of the Small 9 Ball Silicone Mold. Create swirls in the spheres by pouring a little bit of one color into a sphere followed by another, followed by another, until the cavity is full. Unmold the spheres when the soap has fully hardened.

Spheres unmolded

FOUR: Cut the remaining Clear Melt and pour Base into 1-inch cubes and melt in a heat-safe container on 30 second bursts in the microwave. Add the remaining Blackberry Mango fragrance blend and stir until combined. Color with the Shimmer Black Color Block (remember WYSIWYG!) and 1/8 teaspoon Silver Glitter. Stir until the color block shreds have fully melted.

Adding glitter

FIVE: Once the Shimmer Black soap is 130 degrees or below, pour about 1/2 inch layer into the bottom of the mold. Spritz with Isporopyl (Rubbing) Alcohol. Place 2-4 spheres liberally spritzed with Isporopyl (Rubbing) Alcohol into the still soft soap. Spritz again with Isporopyl (Rubbing) Alcohol and allow the layer to harden. Repeat this step, building up the soap and embedding spheres as you go, until the mold is full. Remember that each embed should be liberally sprayed with Isporopyl (Rubbing) Alcohol before being embedded! Allow the soap to fully harden.

Spheres in mold

SIX: Once the soap has fully hardened, unmold and cut the loaf. Each cut will be a unique planetary scene! Wrap the soaps in plastic wrap (or any form of air-tight packaging).
