How to Make Soy Candles in a Slow Cooker
Recipe type: DIY
Prep time: 
Cook time: 
Total time: 
  • Soy wax
  • Natural wicks
  • Essential oils (optional)
  • Small mason jars (half-pint or smaller) or non-porous repurposed containers
  • A slow cooker
  1. Fill the slow cooker with 2 to 3 inches of hot water.
  2. Fill your containers or jars completely full with wax, then place them in the slow cooker with the lid on.
  3. Turn the heat on high and allow the wax to melt, stirring occasionally. The wax will shrink down as it melts, so continue to add more wax until the jar is completely filled (leave around 1” of space at the top)
  4. It takes about 1.5-2 hours for my slow cooker to completely melt all the wax, but yours might be slightly faster or slower, depending on the model. The good news? You don't have to babysit the cooker at all-- just walk away and come back to check when you think of it.
  5. Once the wax is completely melted, remove the jar from the slow cooker and let it cool for 5 to 10 minutes. This will prevent the essential oils from flashing off if/when you add them.
  6. If you are using essential oils, add at least 60-80 drops to each half-pint jar. You can use one scent or combine different scents (see my suggestions below)
  7. Place the wick in the center of the container and keep it in place by winding it around a small dowel or pencil, or propping it in place with small dowels, tape, or pencils. It doesn't really matter how you do it, just as long as it stays straight and in the center of the jar.
  8. Allow the candles to cool and set up completely before trimming the wick to ¼-inch.
