Censer

A censer, incense burner or perfume burner (these may be hyphenated) is a vessel made for burning incense or perfume in some solid form. These vessels vary greatly in size, form, and material of construction, and have been in use since ancient times in many cultures, in both secular and religious contexts. They may consist of simple earthenware bowls or fire pots to intricately carved silver or gold vessels, small table top objects a few centimetres tall to as many as several metres high. Many designs use openwork to allow a flow of air. In many cultures, burning incense has spiritual and religious connotations, and this influences the design and decoration of the censer.

Some types could also be used as pomanders, where the perfume diffuses slowly by evaporation rather than burning.

For direct-burning incense, pieces of the incense are burned by placing them directly on top of a heat source or on a hot metal plate in a censer or thurible.

Indirect-burning incense, also called "non-combustible incense", is a combination of aromatic ingredients that are not prepared in any particular way or encouraged into any particular form, leaving it mostly unsuitable for direct combustion. The use of this class of incense requires a separate heat source since it does not generally kindle a fire capable of burning itself and may not ignite at all under normal conditions. This incense can vary in the duration of its burning with the texture of the material. Finer ingredients tend to burn more rapidly, while coarsely ground or whole chunks may be consumed very gradually as they have less total surface area. The heat is traditionally provided by charcoal or glowing embers.

For home use of granulated incense, small, concave charcoal briquettes are sold. One lights the corner of the briquette on fire, then places it in the censer and extinguishes the flame. After the glowing sparks traverse the entire briquette, it is ready to have incense placed on it.

For direct-burning incense, the tip or end of the incense is ignited with a flame or other heat source until the incense begins to turn into ash at the burning end. Flames on the incense are then fanned or blown out, with the incense continuing to burn without a flame on its own.
