5. Heat the Oil
Once you are ready to begin, pour some boiling water into a large bowl. Pour your chosen oil into the glass jar and place it in the boiling water. The level of the water should be the same as the level of the oil within the jar. Depending on the thickness of your jar, it should only take a few minutes for the oil to heat up. While you are waiting, infuse your oil with some essential oils and natural herbs.
