Grate or chop your wax for easiest melting, and put it in a microwave-safe glass container. I use a Pyrex measuring cup and would definitely recommend something similar with an easy-pour spout.
Measure in your coconut oil, petroleum jelly, and vanilla. A pinch of vanilla powder can be substituted for vanilla extract.
Microwave on high for 60-90 seconds, stirring every 20-30 seconds. You just need to get all the ingredients to their melting point which is approximately 135F degrees.
When fully melted, add essential oils, stir again, and pour hot mixture into prepared tins or pots. Allow to cool and harden. Enjoy!
