Homemade Glycerin Soap

Learn how to make soap using glycerin. Glycerin is usually sold in large blocks at crafts stores; to melt it, cut it into small cubes that will fit in a microwavable bowl or measuring cup. You can also make multiple mini soaps by using ice-cube trays as your molds.

How to do it

Part 1

Step 1

Heat the glycerin in a microwave on high, stirring at 15-second intervals, until it's completely melted.

Step 2

Mix liquid food coloring into a bowl with a coffee stirrer. (Note: Food coloring is very strong, so use it sparingly.)

Step 3

Coat the inside of the milk carton with petroleum jelly. Pour in melted glycerin; let cool completely—about two hours.

Step 4

Tear away carton, and, using a bench scraper, slice block into individual bars.
