The options for soap designs are truly endless when using various scents and pigments in melt and pour soap bases! One of the more popular designs is a layered look in which several colors are layered together into the same bar.

This look can be achieved at home with whatever pigments and fragrances you desire and the process is fairly simple, just follow the steps below.

How to Layer Colors

Step 1: Prepare your first soap layers by melting and mixing in the desired pigments and fragrances.

Step 2: Pour the layer that you wish to be at the top of the finished mold first. You can eyeball this, dividing the mold space between the number of layers you wish to pour. Alternatively, the amounts can be evenly divided by weight to ensure that all of the bars will be the same.

Step 3: Spray the first layer with rubbing alcohol to discourage the formation of bubbles. Allow the first layer to cool just long enough to hold the weight of the next layer (a thick skin will form). This should take approximately as long as it does to prepare your next layer.

Step 4: Prepare the second layer by melting and mixing in the desired pigments and fragrances. When the first layer is deemed ready, score it gently with a fork and slowly pour on the second layer.

If more layers are desired, repeat steps 1-4. Allow to cool as you would for any melt and pour soap bar.


There are a few issues you might run into when creating a layered look.  The most common problem is layers not adhering to one another. This means that after molding, the layers may separate and the bar will no longer exist as intended. There are a few measures you can take to prevent this and other issues though.

  • Run a fork gently across the exposed portion of the first layer, crisscrossing back and forth in both directions before proceeding to pour the next layer. The slippery nature of soap does not allow for layers to easily adhere to one another in their usual state. The act of scoring the hardened soap layer with a fork creates enough texture for a second layer to adhere to the first.
  • Ready a spray bottle with rubbing alcohol. Grease, debris, or bubbles in between layers can prevent layers from to sticking together. Gently spritzing the freshly poured soap layer with rubbing alcohol can help keep grease, debris, and bubbles from forming.
  • Make sure to pour the second layer very slowly and allow the first layer to either form a thick enough skin or hard enough structure to withstand the next pour. Accidental bleeding of one layer into another most frequently happens when one layer has not set enough to hold the weight of subsequent layers.
