Transcript:How to Make Chunk Soap

Hi, I'm David Fisher with About.com. Once you have mastered the basics of soap making, undoubtedly you will want to add some creative touches to your own soaps.

One of the most popular variations is to add chunks or slivers of a previous batch to a new batch of soap you are making. You can do this with either cold process or melt and pour soaps, but to day, we are going to do it with a melt and pour soap base.

Chunk Soap Supplies

For this project you will need:
  • melt and pour soup base
  • selection of some soap safe colorants and/or micas - I have even used a little bit of yellow glitter here
  • plain soap mold - for this project I am using a Plexiglas mold with nine 4 oz. cavities
  • soap safe fragrance oil of your choice
  • the equipment you will need: a scale, a cutting board, knife, measuring cups, and a shredder

Cut Soap Chunks

The first thing we will do is make some chunks. Weigh the soap and put it into your measuring cup. I am making a 4 oz. bar of each of these colors.

Melt the Soap

Melt it in the microwave stirring every 45 seconds or so. Once it is completely melted, add your fragrance oil and colorant. For this one, I am using about 8 drops of liquid red colorant. Stir the colorant and fragrance into the soap and then pour it into the mold. Set the soap aside or pop it into the refrigerator to cool.

Arrange the Hardened Soap Chunks

Once the bars are hardened, pop them out of the mold and cut them into chunks. Here you can add your own creativity: big chunks, little chunks different sizes; it is up to you. You can even shred the soap, like I am doing here. Once your chunks and/or shreds are prepared, arrange them into the molds. Mix them up, layer them, arrange them however you like.

Make the Chunk Soap

Now it is time to do the over pour. You want to melt your soap (I am melting about 16 oz here) into your measuring cup. However, once it is melted you need let it to cool till it is about 120 degrees. If you pour it over the chunks while it is still very hot, you will cause the chunks to melt and some of them will bleed color into the over pour.

Spritz the chunks with a little rubbing alcohol. Once the soap has cooled to about 120 degrees, gentle pour it over the chunks. Gently tap the mold on the counter top to dislodge any air bubbles that may have gotten trapped. Set the soap bars aside or into the refrigerator to cool.

Finish the Chunk Soap

Once the soaps have cooled and hardened completely, simply turn the mold over and give them a little press and they will pop out of the mold. That is all there is to it! Different combinations of chunks and shapes make different themed soaps.
