This Moonstone Cold Process Soap is topped with Snowflake Sparkle, Aqua Pearl, Rose Pearl, and Lavender Mica. You can place the colors on top of the soap easily using our powder sprayer. All you have to do is press the top of the sprayer and the mica is dusted onto your soap. It’s an easy way to work with powders, and also happens to be pretty fun to use.
This recipe is scented with Rose Quartz Fragrance Oil, which is a combination of soft floral, light powder, and sweet fruit. It has notes of lavender, bergamot, jasmine, violet, sandalwood, and vanilla.
This recipe was made with discontinued Moonstone Fragrance Oil, which discolors to a soft brown. To combat the discoloration, we added a large amount of titanium dioxide pigment. The soap is now scented with non-discoloring Rose Quartz Fragrance Oil, so you can decrease the titanium dioxide or leave it the same for brighter bars.

Moonstone Cold Process Soap Project
It’s amazing what a little mica can do. This soap has a layered design, but what makes it special is the glimmer on top.
5 lb. Wood Mold with Sliding Bottom
Silicone Liner for 5 lb. Wood Mold
54 oz. Basic Quick Mix
7.7 oz. Sodium Hydroxide Lye
15.1 oz. Distilled Water (15% water discount)
3.5 oz. Rose Quartz Fragrance Oil
4 tsp. Titanium Dioxide
Snowflake Sparkle Mica
Aqua Pearl Mica
Rose Pearl Mica
Four Powder Sprayers
FRAGRANCE PREP: Measure 3.5 ounces of Rose Quartz Fragrance Oil into a glass container. Set aside.
COLORANT PREP: To ensure that the titanium dioxide blends smoothly into the soap batter, we recommend micronizing it before dispersing it in oil. Please note this is an optional tip, but it does help with the titanium dioxide clumping in the soap. To micronize colorant, simply use a coffee grinder to break up any clumps of color and prevent streaks of white from showing in the final soap. We like to use a coffee grinder that has a removable stainless steel mixing area for easy cleaning. Next, disperse 4 teaspoons of titanium dioxide into 4 tablespoons of sunflower or sweet almond oil (or any other liquid oil). In separate containers, disperse 1/2 teaspoon of Aqua Pearl Mica, Lavender Mica, and Magenta Mica into 1/2 tablespoon of liquid oil. Use a mini mixer to work out any clumps. Fill the four powder sprayers separately with Snowflake Sparkle Mica, Lavender Mica, Rose Pearl Mica, and Aqua Pearl Mica. Set aside.
SAFETY FIRST: Suit up for safe handling practices. That means goggles, gloves, and long sleeves. Make sure kids, pets, other distractions, and tripping hazards are out of the house or don’t have access to your soaping space. Always soap in a well-ventilated area.
Slowly and carefully add 7.7 ounces of lye to 15.1 ounces of water and gently stir until the lye has fully dissolved and the liquid is clear. Set aside to cool. Optional: Add 3.5 teaspoons of sodium lactate to help harden the soap so it unmolds more quickly.
Fully melt the entire bag of Basic Quick Mix until it’s completely clear and there is no cloudiness. Shake the bag to mix up all the oils. Measure 54 ounces into a large heat-resistant container. Once the lye water and the oils have cooled to 130° F or below (and are ideally within 10 degrees of each other), add the lye water to the oils and stick blend the mixture to a thin trace.
Add all of the dispersed titanium dioxide and Rose Quartz Fragrance Oil to the soap. Use a whisk to thoroughly mix in. If the mixture is still very thin, quickly pulse it with the stick blender to thicken the soap to a light medium trace.
Pour 17 ounces of soap equally into 3 separate containers. Add the following dispersed colorants and use a whisk to fully mix them in.
Pour 1/3 of the white soap into the mold (it’s okay to eyeball it). Use a spoon to evenly spread the soap throughout the mold. Don’t worry about the layer being straight. Tap the mold on the counter to help get rid of bubbles.
Pour half of the blue soap onto the white. Use a spoon to spread the blue soap throughout the mold. Again, don’t worry about the layer being straight.
Use the powder sprayer filled with Snowflake Sparkle Mica to completely cover the blue layer of soap with mica. NOTE: We sprayed Snowflake Sparkle Mica in between the layers of this soap. The final effect is not quite as noticeable as we thought it would be. You can skip these steps if you’d like, or follow the instructions as written if you like as much sparkle as possible.
Pour half of the pink soap onto the blue layer. Use a spoon to spread the soap throughout the mold. Then, use the powder sprayer with Snowflake Sparkle Mica to completely cover the pink layer.
Cover the pink layer with half of the purple soap. Use a spoon to evenly spread the soap. Use the Powder Sprayer filled with Snowflake Sparkle Mica to completely cover the purple layer. Tap the mold firmly on the counter to help get rid of bubbles.
Repeat this layering process with another 1/3 of the white soap and the remaining blue, pink, and purple soaps. Between the blue, pink, and purple layers, use the powder sprayer again to completely cover the soap with Snowflake Sparkle Mica.
Tap the mold firmly on the counter to help get rid of bubbles. Cover the purple layer with the remaining white soap and use a spoon to evenly spread the soap throughout the mold. Then, use the spoon to create texture on the top. There is no right or wrong way to create texture, so have fun with it!
Once you’re happy with the top, use the powder sprayer to completely cover the top with Snowflake Sparkle Mica.
Use the powder sprayers filled with Lavender Mica, Aqua Pearl Mica, and Rose Pearl Mica to spray the colors on the top of the soap in different areas. There is no right or wrong way to layer the colors, so have fun with it! But remember – you can always add more color, so start slow. Adding too much color will take away the soft pearly look. Less is more in this case!
Once you’re happy with the top, allow the soap to stay in the mold for 2-3 days. Because it has a water discount, you may be able to unmold it faster than a normal recipe. Once it’s ready, unmold and cut into bars. Allow to cure for 4-6 weeks. Enjoy!
