Ingredients
- Clear glycerin soap
- Food coloring
- Coffee stirrers
- Clean milk or juice carton
- Petroleum jelly
- Optional: Essential Oil
Preparation
Step 1
Heat glycerin in a microwave on high, stirring at 15-second intervals, until it's completely melted.
Optional: Add several drops of essential oil to your soap if desired, as well as any moisturizers or vitamins. Stir gently and thoroughly.
Mix liquid food coloring into bowl with a coffee stirrer. (Food coloring is very strong, so use it sparingly.)
Coat the inside of the milk carton with petroleum jelly. Pour in melted glycerin. Let cool completely (about 2 hours).
Tear away carton, and, using a bench scraper, slice block into individual bars.
