Instructions

First, infuse olive oil with calendula by following these instructions.
Measure all of the ingredients into a small double boiler or a Turkish coffee pot. I like to use the Turkish coffee pot because it has a pour spout. I can heat the oils up quickly and then pour them easily into the tubes.
Once the oils, waxes, and butter have all melted together, turn off the heat and add in the essential oils. Stir well with a small spatula.
When everything is thoroughly mixed, use the spout on the Turkish coffee pot to pour the lip balm into the tubes. Fill each tube to just above where the center screw is.
Let the lip balm cool and then warm up the remaining mixture in the pot so that you can top off each one of the tubes. Filling the lip balm tubes in two steps ensures that you won’t have a large depressed area with a hole in the center of the lip balm. If this still happens, then you can always add a little bit more lip balm onto the top of the depressed area and use a lighter to melt it onto the rest of the lip balm. If this recipe is just for your own use (and you don’t really care what it looks like) then just fill up each one of the tubes the first time; it won’t affect the final product’s function or usefulness.
