All About Melt and Pour Soap

Melt and pour soap is a great way to get exactly what you are looking for in your soap without having to work with lye. Melt and pour soap is already made soap that you can customize with color and scent to make it your own. There are so many different variations of melt and pour soap, we will get into more detail on that later.

Ways to Melt Soap Base:

  1. Microwave oven (50% power)
  2. A water jacketed melter.
  3. For Simplicity you can use a double boiler pan with hot water in between.
  4. Instructions for double boiler are similar to microwave.


  1. Thinly slice, chunk or grate the soap base for ease of melting.
  2. Place the soap in a Pyrex cup and microwave it for 30 seconds (for half a pound).
  3. Remove and stir slightly.
  4. Continue to microwave for another 30 seconds (times may vary depending on the microwave).
  5. Add soap colorant and stir until blended (soap colorant should be minimal).
  6. Add soap fragrance (1 ounce of fragrance per 2 pounds of soap) and stir gently and thoroughly.
  7. Pour soap into soap molds. Let cool and harden before popping out of molds.
  8. For fast set, allow the soap to cool for 10 minutes and place in refrigerator (not the freezer) until set.

Tips and Tricks:

  1. Never allow the soap to boil. Boiling might denature the color and cause a yellowish hue.  A small drop of violet color will restore your soap to white or clear color.
  2. Children require adult supervision and should not handle the hot and molten soap.
  3. Ideally the soap temperature prior to pouring should be about 120 degrees. In other works you can put your finger in the soap and it shouldn’t hurt.
  4. Do not over stir when mixing colors and fragrances. But if this happens allow 10 minutes of settling for the release of air bubbles. Air bubbles if trapped in the mold will spoil the transparency.
  5. Always pour on a leveled surface.
  6. When placing an insert or an object in the soap, pour the first layer and let cool, insert the object, and when pouring the second layer it has to be higher in temperature up to 150 degrees. Otherwise separation of the two layers might occur.
  7. Avoid diluting the soap with water or any other chemical. The only exception to this is to add a maximum of 5% glycerin should you need a softer or more transparent soap.
  8. Avoid contact of soap with eyes.
  9. To eliminate air bubbles once poured, spray alcohol on the surface.
  10. Be conscience of where you purchase melt and pour bases from and their ingredients. We have a great selection with high quality ingredients here.
