Tools You Need to Use Melt and Pour Soap Base

There are several tools you need to make melt and pour soap. If you’re only planning on doing this project once or twice, you can probably use items you already have at home. However, if you decide to make soaps frequently, you may want to keep a few of these items on hand specifically for soap making.

Ingredients to Make Soap

You can make great soap with only a few ingredients. Technically, to make soap, you don’t need any other ingredients beside the base. However to make fancier soaps, you may want a few additional ingredients.

I use a microwave to melt my soap base. If you don’t want to use the microwave, you will need a small pot that your Pyrex measuring cup will fit down in or you can use a double boiler.

How to Melt the Soap Base

To melt the soap base, you need to cut the soap into small cubes using a bench scraper (or knife) and the flexible cutting board. The cubes should be about 1/2″ or less. Bend the cutting board and pour them into the Pyrex measuring cup.

Place the measuring cup in the microwave and heat for 30 seconds. (No need to cover. The soap base doesn’t splatter.) Remove from the microwave and stir. Continue heating in 30 second intervals and stirring after each one until the soap base is mostly melted.

Caution: Do NOT overheat the soap base. You can always microwave for 10-15 seconds more if needed to melt the remaining bits of soap.

When stirring the soap, try to stir gently. Stirring vigorously can cause unwanted air bubbles. While this doesn’t affect the soap’s cleansing properties, the bubbles can be unsightly.

Adding Color and Fragrance

Once the base is totally melted, add any soap coloring, mica, and/or essential oils. Stir well to distribute the color throughout. If you notice any unmelted chunks, you can microwave the soap for an additional 10-15 seconds and then gently stir to finish melting.

If you wish to add any other ingredients to the soap like chia seeds, oatmeal, walnut shells, etc. add them next, stirring gently until incorporated. Many of these ingredients may sink to the bottom of the soap mold when you pour the soap.

I always add the essential oils last, just before pouring into the molds. This allows the soap to cool briefly since the heat can cause the scent to dissipate. You can get my free printable of over 30 essential oil combinations by signing up below.

Pouring the Soap

Once everything is added, the soap mixture is ready to be poured into the molds. Be sure the mold is placed on a flat surface where it can sit for at least an hour. Fill each mold to just below the rim.

Immediately spray the soap in the molds with the alcohol. This will remove any bubbles from the surface. If you have extra soap, it can be poured into a plastic container. (I keep a few of these containers on hand for excess soap. We use these soaps ourselves.) Allow the soap to cool, undisturbed for at least an hour.

Before unmolding, check to be sure the soap is completely cool. If it still feels warm, wait another 30 minutes before attempting to remove it. Removing the soap too soon can cause the soap to be deformed and make it much more susceptible to nicks.

To remove the soap, turn the mold upside down and press gently on the mold until the soaps pop out. If they are being stubborn, (and mine usually are) you can put the soap in the freezer for 15 minutes to firm it up a bit. Then try again to release the soap.

Did You Know You Should Wrap Melt & Pour Soap?

Melt and pour soap looks beautiful sitting out, however, since it is glycerin based, it will sweat in high humidity. While this doesn’t affect the soap, it does make it less attractive. To prevent this, you need to wrap each bar individually in plastic wrap. You can gift them just wrapped in the plastic, or put a label over the plastic.

If you want to shrink wrap your soap, you can do so quite easily. A hair dryer works okay, but if you (or your husband) have a heat gun laying around it will make for a much more professional job.

You don’t need any special soap wrappers. Regular plastic wrap works just fine. After much trial and error, I have found that the cheap plastic wrap actually works best for this trick. (If you have a Food Lion near you, their brand is my favorite!)

Once you have each bar of soap wrapped, gently run the heat gun over the soap, keeping the gun moving at all times. The plastic wrap will shrink to fit your soap. Use caution while doing this to ensure you don’t burn your fingers, the soap, or anything else!

Lime & Cedarwood Soap Recipe

I wanted to share an easy, yet beautiful, melt and pour soap recipe with you so you could try this out yourself. This recipe comes from Maura at Happy Deal Happy Day. She has graciously given me permission to share it with you.

Maura’s original recipe used 2 pounds of soap base and made 12 bars. I halved her recipe and made 4 large bars since my soap mold is pretty big. For this specific recipe you will need the following ingredients in addition to the tools listed above:

Lime & Cedarwood Soap with Chia Seeds
Prep Time
15 mins
Cook Time
15 mins
Cooling Time
1 hr
Servings: 4 bars
  • 1 lb. clear melt & pour soap
  • 12 drops lime essential oil
  • 7 drops cedarwood essential oil
  • 1/2 tsp. chia seeds
  • 3 drops yellow soap coloring
  • 1 drop blue soap coloring
  • 1/8 tsp. gold mica powder
  1. Cut soap into small cubes and place in Pyrex measuring cup. Melt in the microwave in 30 second increments, stirring after each increment, until soap is just barely melted. Do NOT overheat.

  2. Once soap is melted, stir in soap coloring, mica, and essential oils.

  3. Pour soap into molds and allow to harden for at least 1 hour before removing from mold.

  4. Remove soap from mold and wrap in plastic wrap.

I love using this soap beside our utility sink. The chia seeds help to scrub off garden dirt from my hands. And afterwards, I apply a bit of my Homemade Hand Salve to soften my skin.
