What’s in This Lava Ombre Soap Recipe?

6 Cavity Soap Mold

This amazing temperature-resistant soap mold will help you concoct six gorgeous soap bars.

Melt & Pour Soap Base

This recipe requires two melt-and-pour soap base types! We like to use glycerin, which gives the soap its vibrant colors, and shea butter which creates a creamy white base.

Mica Powder

So whether you want to bask in the beautiful Tiger Orange, feel regal with fascinating Fuchsia, or light up your life with the inviting Yellow Gold, mica powder allows us to achieve our dream colors easily. 

Lava Essential Oil Blend

Lava Essential Oil Blend is a must-have for any fan of tropical sunsets! Its invigorating scent will leave your skin feeling refreshed and ready to tackle the day. Yet, at the same time, its vibrant and uplifting energy will remind you of vacation days spent lounging in the sun.

Isopropyl Alcohol (in a spray bottle)

The key to an even, perfect melt that looks amazing? Isopropyl Alcohol in a spray bottle. This powerful liquid works like magic to prevent bubbles from forming on the soap and helps bind the soap bases together for flawless results.

Two Small Books

Making an ombre melt-and-pour soap can be a breeze if you’ve got the right tools – like two small books! Having it on hand will let you elevate your soap mold just the right way to layer your colors diagonally – so that the ombre effect will look amazing.

Lava Ombre Soap Recipe

Lava Ombre Melt & Pour Soap Recipe


  • 6 Cavity Soap Mold

  • 2 lb Shea Butter Soap Base

  • 2 lb Glycerin Melt & Pour Soap Base

  • Fuchsia Mica Powder

  • Tiger Orang Mica Powder

  • Yellow Gold  Mica Powder

  • Lava Essential Oil Blend

  • Isopropyl Alcohol (in a spray bottle)

  • 2 small books


  • Place two books under each side of your mold so that it creates a slight v shape (3 cavities halfway onto one book and 3 cavities halfway onto the other). 
  • Cut your glycerin soap in half. Take one half and cut that in half so you end up with ¼ of the soap block. Cut this ¼ into 1-inch cubes. Store the rest of the soap for future use. 
  • Divide your cut-up soap into three portions.
  • Take one portion of soap, and melt it.
  • Add a dash of Fuchsia mica powder along with 10 drops of Lava Essential Oil Blend and stir.
  • Pour a small amount of soap into each cavity of the soap mold. Allow it to set.
  • Take another portion of your soap and melt it. Add a dash of tiger orange mica powder and 10 drops of Lava Essential Oil Blend and stir.
  • Spritz the pink layer of soap with isopropyl alcohol, then pour the orange soap over the pink layer. 
  • Take your remaining glycerin soap and melt it. Add a dash of yellow mica powder and 10 drops of Lava Essential Oil Blend and stir. 
  • Once the orange soap has been set, remove the books from beneath the mold. Spritz it with isopropyl alcohol and add the yellow soap over the orange layer.
  • While the yellow layer sets, take your shea butter soap base and cut it in half. You will be using about half of the soap base for this recipe. Store the rest for later use. 
  • Cut the soap into 1-inch cubes and melt. Add 10 drops of Lava Essential Oil Blend and stir.
  • Spritz the yellow soap layer with isopropyl alcohol. Fill each soap cavity the rest of the way with the shea butter soap base. Spritz the soap with isopropyl alcohol to prevent bubbles. 
  • Once the soap has been set, remove it from the mold and enjoy! 


  • *If you have a scale at home, you can instead weigh out 7 oz glycerin soap and 15 oz shea butter soap.

Tips for Making Lava Ombre Soap

Melting Soap

One of the first steps to this recipe is cutting your soap into 1-inch cubes. This helps the soap melt more evenly. It’s easy to overheat soap, so we want to avoid big chunks of soap that will take longer to melt compared to smaller chunks in the same bowl.

You can melt soap on the stove using a double boiler, straight into a pot, or in a liquid measuring cup in the microwave. Using the stove will make it easier to control the temperature of your soap, but it takes longer. Using a microwave will be faster, but microwaves don’t heat things evenly. To melt the soap in the microwave, you’ll need to use 30-second intervals and stir between each interval.

You want your soap to melt but not bubble up. Soap that is boiling has been overheated. It will still function as a soap but will affect the look of your design. The soap bar will be harder and more brittle.

When first starting with melt and pour soap, I recommend melting it on the stove, so you have more control over how it’s melting.

Soap Layers

For this recipe, we will be creating layers of soap. Between each layer of soap, you must spray it with isopropyl alcohol; otherwise, the layers will fall apart.

We’ll use a book to tilt our mold to create diagonal layers of soap. You’ll want your book to be on the smaller side so that your layers aren’t too big.

As you’re laying soap, you’ll want to be mindful of the temperatures of your soap layers. In addition, you need to ensure the soap layer you have just poured is set enough to hold the layer above it.

You’ll know the layer is set enough if you can touch it gently with your finger without the layer breaking.

You’ll also need to make sure the layer of soap isn’t too hot; otherwise, it will melt your previous layer, and you won’t end up with clearly defined layers of soap.

The soap you are about to pour should be between 125-135° F. If you don’t have a thermometer at home to check the temperature, look for a skin layer of soap on top of your soap. This will indicate the soap is cool enough to be poured.

Mica Powder

For this recipe, we are using four different colors of mica powder. You can swap these colors out for any that you’d like. You can also use fewer or more colors depending on your preference.

When you add the mica powder to the soap, it will at first clump. You can prevent this by first dispersing the mica powder in a small amount of rubbing alcohol. You can also remove clumps by stirring.

Glycerin Soap

Simply Earth glycerin soap will be cloudy and white in the packaging. However, once you melt it, it will become clear and will create vibrant semi-transparent soap when we add the mica powder.

Rubbing Alcohol

Rubbing alcohol is an important ingredient for melt-and-pour soap. Spraying it over layers of soap will prevent air bubbles and help bind layers of soap together.

Lava Essential Oil Blend

This blend of essential oils has a natural orange tint. Because of that, we add it only to the glycerin soap base. We also add mica. We don’t want the color of the essential oil to tint our shea butter soap base. We want our glycerin soap base to be as white as possible.

Reuse Melt & Pour Soap 

If you end up with too much soap for your recipe, you can pour the extra soap into a soap mold. This can be remelted and used in later melt-and-pour soap recipes.

If you have too little soap, simply cut and melt more soap.
