Candle fragrances allow you to enjoy not only the light, but the aroma of your candle. Candle fragrances have oils that must be pure not containing any other ingredients such as water or alcohol. They are derived from plants and flowers and are highly concentrated and are more costly than other scents used in different projects. Make sure you know what you are using and how to use it before incorporating these wonderful scents into your wax making venture. Since they may have medicinal qualities, some of these candle fragrances must be handled very carefully.
