Insense is used in may different ways. And you are wondering what is the significance of insense and what it is purpose? Well, according to Wisegeeks.com:
"For centuries, people have been using incense for religious or spiritual, aesthetic and therapeutic reasons. Today, incense is still used for these purposes, as well as for creating a pleasant atmosphere and scent to enhance the ambiance of a home. Because of its long history, incense has evolved into many different types and forms, from its scent, to its shape, to the way it burns.
Stick incense is probably the most common form of incense. The gum or resin from which the incense is made coats a long thin stick that burns slowly, releasing the particular fragrance that it contains. Stick incense can also be solid so there is no stick center or core, only a solid chunk of incense material.
Spiral incense is similar to the stick incense, but it is shaped in a coil. Spiral incense burns very slowly, lasting for hours or days depending on its composition. This type offers an interesting form in addition to its fragrant properties.
Cone incense is a chunk of the same gum or resin used in the types described above, but it stands alone in the form of a cone. It is lit at the tip and burns down, releasing more smoke and fragrance as it nears the base. Cone incense, because of its mass, does not burn uniformly as stick incense does. Cone incense is lit and extinguished, leaving a burning ember which continuously releases smoke and fragrance.
Powdered incense is usually reserved for religious ceremonies. The amount of preparation required to burn it is often inconvenient for someone who only wishes to enhance their surroundings. Powdered incense is burned in a censer, a container for burning incense. This type of incense, along with others that are made purely of resins, require a separate heat source. Traditionally, these are often burned directly on hot ash, coal or specially made heated plates.
Incense comes in a variety of different colors and fragrances. Fragrances are created from different organic plant materials, animal derivations such as musk and essential oils that are extracts of either or both. The fragrance can be a single scent found naturally or a combination of two or more ingredients. The combinations of incense scents are endless, as is the variety of burners and paraphernalia that hold them."
