Essential oils on their own perform beautifully when using a diffuser - it only takes a few drops of oil in a diffuser. Making a candle requires around 30 times as much oil. It takes a good deal of resources to produce essential oils. For example, to produce one 5 ml bottle of high quality rose essential oil takes about 22 pounds of rose petals. At Glim + Glow Home we have opted for a eco-friendly approach to crafting our products.
