Measure your oils, wax, and butter together in a Turkish coffee pot or mini double boiler. Melt over low heat.
Once all melted, remove from heat and stir in your essential oils. Stir with a small spatula.
Use the pour spout on the Turkish coffee pot to pour into lip balm tubes. Fill halfway, then let it set and cool. Once cool, reheat the remaining mixture and pour the rest to the top of the tubes. This helps to prevent a large-depressed area in the center of the lip balm.
