Step 1: Create a lye solution. Weigh the water and lye into two separate containers. Slowly pour the sodium hydroxide into the water while stirring. Stir until completely dissolved and set aside to cool.
Step 2: Prepare the base oils. First, weigh any solid oils and butters into a container and melt. You can melt using the microwave or low heat on a burner. Next, weigh each liquid oil into the melted oils. The liquid oils will cool down the melted oils and leave you with a base oil mixture that is about at the correct temperature to make soap. It might still need to cool down a bit.
Step 3: Weigh your slow-moving essential oil or fragrance oil into a glass or stainless steel container and add to your base oil.
Step 4: Prepare your mold. If you need to line your mold, line it.
Step 5: Check the temperatures. You should now have a container containing liquid base oils and a container containing lye solution. Take the temperatures using an infra-red temperature gun. Be sure to stir each mixture before taking the temp. You want your temperatures to be between 80-100 degrees F.
Step 6: Once you have reached desired temperatures, pour the lye solution into the oil mixture and mix to emulsion.
Step 7: Once emulsified, divide your soap to color. I divided mine into 8 cups.
Step 8: Add colorants to each cup and mix well using a mini-mixer. I mixed some of my colorants to create a more diverse color scheme.
Place a funnel in your PVC pipe to pour your colors into. You don’t HAVE to have a funnel, but it does help keep the soap pouring in one place without moving around. Make sure the bottom of the mold is secure! You don’t want soap coming through. You can purchase PVC caps, or you can secure with plastic wrap and rubber bands. I always place my mold inside of another container in case it leaks!
Step 9: Rotating through each color at least 6-10 times, pour each cup of colored soap into the funnel that is sitting at the opening of the mold. The funnel helps the soap to fall into the center of the mold. Small pours will create thin rings and heavy pours will create thicker rings. When you get closer to the top of the PVC mold, you might have to lift the funnel out and hold it with your other hand as you pour. The soap might look like it is muddying up as you pour, but when you go to cut you’ll find the beautiful pattern.
Step 12: Allow your soap to saponify and harden for at least 24 hours. After 24 hours, you can unmold and cut. Cure your soap for 4-6 weeks.

Learn to control trace, so it doesn’t control you!
This detailed video training explores the difference between emulsion and trace, so you know when to stop mixing your soap, allowing enough time to color and execute intricate designs. You’ll leave the eClass with a greater understanding of how water/liquid, temperatures, base oils, fragrance oils, essential oils and additives all affect the movement of your soap to trace.
