Things You'll Need:
- 1 liter fat 4 1/2 ounces lye Gloves Goggles 2 glass bowls Wooden spoon 20 drops food coloring Soap molds Plastic wrap
-
Step 1
Store up 1 liter of fat. It may be accumulated over time. For example, bacon produces great fat to use for making soap, but you must cook at least 10 pounds of bacon to get 1 liter of fat. Get a liter container, and add fat to it until it is full.
-
Step 2
Pour 8 cups water in a pot, and bring it to a boil. When it boils, add the fat. Bring the mixture back to a boil, and then let it simmer for 60 minutes. Remove the mixture from heat, and let it cool in a refrigerator for 4 hours.
-
Step 3
Return the pot to the stove, and turn the heat to medium. You want to liquify the fat again but not make it so hot that it boils.
-
Step 4
Place the lye and 2 cups water in a glass bowl. Use cold water so the lye does not fizz and splash on you. Wear gloves and goggles for protection from the lye if it splatters. Lye can burn your skin.
-
Step 5
Remove the fat from the stove, and pour it into a second glass bowl. Slowly add the lye to the fat. Mix the lye and fat continuously with a wooden spoon. Watch for the ingredients to begin to thicken, about 10 to 15 minutes into stirring. When the mixture thickens, add the food coloring. The color you choose is a personal choice: If you want green soap, use green food coloring; if you want red soap, use red food coloring.
-
Step 6
Mix the fat and lye for another 5 minutes, then pour the mixture into soap molds. If you do not have soap molds, use cookie molds, but you will not want to use them for cookies again.
-
Step 7
Cover the molds with plastic wrap, and store them at room temperature for 12 days before using.
