Incense is said to have originated many thousands of years ago.  Over time, the practice of burning incense spread to the sprawling metropolises of the great civilizations. There are countless assortments of incense (including stick incense, resins, and powders); incense cones were popularized by the Oriental Cultures of the East and were first introduced at the World’s Fair in the late 1800's. Some common incense scents used for incense cones come from essential oils, resins, roots, flowers, leaves, seeds, fruits, and gums. Inexpensive, artificial scents can also be formed through man-made, chemical processes but are decidedly less popular and effective.
