Recipe Directions

  1. NOTE: If you are making these products for sale, good manufacturing practices recommend you wear a hairnet, gloves and a mask. We also recommend a clean apron.
  2. Remove soap from both of the plastic trays. Cut soap into small chunks and place in a large (64 oz. or larger) mixing bowl.
  3. Place silicone mold on a large cookie sheet. This will add stability should the mold need to be moved.
  4. Place bowl in microwave and heat soap until it has completely melted. Heat for about 3 minutes, remove and stir. Continue to heat in 1 minute intervals until soap has completely melted.
  5. Add 1 oz. of Rockin Raspberry fragrance oil and stir well. Pour into silicone tray mold. Spritz top of soap with alcohol to release any surface bubbles.
  6. Allow soap to completely set up. This may take a full day before soap has completely hardened.
  7. Once set up, turn soap over and gently press on mold to release soap. Turn large soap over to see the score lines on the soap.
  8. Gather enough small glass bowls for the number of colors being used to paint with.
  9. Cut each color block into 4 pieces. Place one piece of each color into each of the bowls. Add 1/4 teaspoon of glycerin to each bowl.
  10. Place each bowl in microwave and heat for 5 seconds. If color has not completely melted, heat for another 3-4 seconds.
  11. These colors will harden fairly quickly once melted. They can be reheated a few times, adding a little more glycerin if needed. Be sure to only heat for a few seconds.
  12. Using a child's paint brush, let them paint on the soap. They can make one big picture or they can paint something on each of the 12 soap bars.
  13. If they make a big picture, once the soap is cut into bars, they can put the pieces back together like a puzzle.
  14. When using the soap, if there is a large amount of color, you may want to wash some of the color off before using. Too much color may come off on washcloths or color the skin.

WSP Questions And Answers

"A while back I read in an old soap-making book something about "soap paints" in regard to adding painting designs on soap. Is there a specific product known as "soap paint" or was that maybe just a reference to any kind of soap colorant used to create design? Just curious and figured if anyone would know it would be you!"
