Add a few inches of water to a skillet and place on your stove at medium low heat.Place a glass jar in the water and add your beeswax to the jar. Allow the beeswax to melt - this takes 15 or more minutes.Once the beeswax has melted, add the remaining oils (except essential oil) and shea butter and let melt - this takes an additional 15 or more minutes. You don't have to stir - the oils will naturally blend together.Once everything is melted and liquid, remove the jar from heat and add in your essential oil, if using.Pour liquid into jars of choice (I like using THESE - this recipe fills 2 of those jars) and place on the counter for a few hours to harden. You can speed up the hardening process by placing the jars in the refrigerator for at least a half hour.
