- 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.
- Using a soap slicer, cut clear soap into 1-2 inch pieces. The soap slicer is dull and perfect for this project. Do not use a knife as it is very sharp and the soap is slippery. The knife could slip causing injury.
- Using a microwave safe glass bowl, place 1 lb of clear soap in a microwave and heat for 30 seconds. Stir well. Repeat until soap is completely melted.
- Cut a 1/2 to 1 cube of blue color from the color bar. Place into soap and stir. The color bar will melt as you are stirring. Depending on your preference, you can add more color.
- Add 1/2 oz (1 Tablespoon or 15 ml) of fragrance into colored soap. Mix well.
- Immediately pour the blue soap into the mold until the cavity is 1/2 to 3/4 full.
- Using a soap cutter, carefully cut white soap into 1/2" cubes.
- When colored clear soap has cooled to 130-134ºF, hold the soap cubes in your hand and apply a spray of rubbing alcohol. Be generous! It is the rubbing alcohol that allows the white and clear soap to adhere to each other.
- Place cubes of soap into bar. Add enough cubes so that bar is completely full.
- Spritz top of soap with rubbing alcohol. (This will pop bubbles and give a smooth surface to the soap)
- Allow soap to naturally re-harden. Remove from mold and place in cello bag.
- Tie with tin ties. Use one silver and one blue tin tie per bag. For a fun look, twist ties around a pencil to create a spiral curled appearance.
- If you are sellling your soap, don't forget to label the soap to complete the package. Label according to FDA cosmetic label guidelines.
