Censers are any type of vessels made for burning incense. These vessels vary greatly in size, form, and material of construction. 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.
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.
Censers made for stick incense are also available; these are simply a long, thin plate of wood, metal, or ceramic, bent up and perforated at one end to hold the incense. They serve to catch the ash of the burning incense stick.
In Taoist and Buddhist temples, the inner spaces are scented with thick coiled incense, which are either hung from the ceiling or on special stands. Worshipers at the temples light and burn sticks of incense. Individual sticks of incense are then vertically placed into individual censers.
The history of censers in Chinese culture probably began in the late Eastern Zhou Dynasty (770–256 BCE). The Chinese words meaning "censer" are compounds of lu (爐 or 炉 "brazier; stove; furnace"), which originated as a type of Chinese bronze. Xianglu (香爐, with "incense") "incense burner; censer" is the most common term. Xunlu (熏爐, with "smoke; fumigate; cure (food) with smoke", or 薰爐, with "fragrance; an aromatic grass") means "small censer, esp. for fumigating or scenting clothing; censing basket", which Edward H. Schafer described.
"Censing baskets" were globes of hollow metal, pierced with intricate floral or animal designs; within the globe, an iron cup, suspended on gimbals, contained the burning incense. They were used to perfume garments and bedclothes, and even to kill insects.
Shoulu (手爐, with "hand") means "hand-held censer; handwarmer".
The boshanlu (博山爐 "universal mountain censer" or boshan xianglu 博山香爐) or hill censer, which became popular during the era of Emperor Wu of Han (r. 141-87 BCE), displayed a microcosmic sacred mountain (esp. Mount Kunlun or Mount Penglai). These elaborate censers were designed with apertures that made rising incense smoke appear like clouds or mist swirling around a mountain peak. The Han Dynasty scholar Liu Xiang wrote a (c. 40 BCE) boshanlu inscription:
I value this perfect utensil, lofty and steep as a mountain! Its top is like Hua Shan in yet its foot is a bronze plate. It contains rare perfumes, red flames and green smoke; densely ornamented are its sides, and its summit joins azure heaven. A myriad animals are depicted on it. Ah, from it sides I can see ever further than Li Lou [who had legendary eyesight].
Archeologists excavated many (c. second century BCE) boshanlu at Mawangdui, and some contained the remains of ashes. Analysis revealed aromatic plants such as maoxiang (茅香 "Imperata cylindrica, thatch grass"), gaoliangjiang (高良薑 "Galangal"), xinyi (辛夷 "Magnolia liliiflora, Mulan magnolia), and gaoben (藁本"Ligusticum sinense, Chinese lovage"). Scholars presume burning these grasses "may have facilitated communication with spirits" during funeral ceremonies.
According to the sinologist and historian Joseph Needham, some early Daoists adapted censers for the religious and spiritual use of cannabis. The (ca. 570 CE) Daoist encyclopedia Wushang Biyao (無上秘要 "Supreme Secret Essentials"), recorded adding cannabis into ritual censers. The Shangqing School of Daoism provides a good example. The Shangqing scriptures were written by Yang Xi (楊羲, 330-386 CE) during alleged visitations by Daoist "immortals", and Needham believed Yang was "aided almost certainly by cannabis". Tao Hongjing (陶弘景, 456-536 CE), who edited the official Shangqing canon, also complied the Mingyi bielu (名醫別錄 "Supplementary Records of Famous Physicians"). It noted that mabo (麻勃 "cannabis flowers"), "are very little used in medicine, but the magician-technicians ([shujia] 術家) say that if one consumes them with ginseng it will give one preternatural knowledge of events in the future." Needham concluded,
Thus all in all there is much reason for thinking that the ancient Taoists experimented systematically with hallucinogenic smokes, using techniques which arose directly out of liturgical observance. … At all events the incense-burner remained the centre of changes and transformations associated with worship, sacrifice, ascending perfume of sweet savour, fire, combustion, disintegration, transformation, vision, communication with spiritual beings, and assurances of immortality. Wai tan and nei tan met around the incense-burner. Might one not indeed think of it as their point of origin?
Chinese censers were popularly shaped like a bird or animal, sometimes designed so that the incense smoke would issue from the mouth.
Examples are usually of globular form with three feet, made in pottery, Imari porcelain, Kutani ware, Kakiemon, Satsuma, enamel or bronze. In Japan a similar censer called a egōro (柄香炉?) is used by several Buddhist sects. The egōro is usually made of brass with a long handle and no chain. Instead of charcoal, makkō powder is poured into a depression made in a bed of ash. The makkō is lit and the incense mixture is burned on top. This method is known as Sonae-kō (Religious Burning).
Decorated ceramic incense burners were in general use in Mesoamerica, particularly in the large Central-Mexican city of Teotihuacan (100-600 AD) and in the many kingdoms belonging to the Maya civilization. Mayan censers, which had a reservoir for incense on top of a vertical shaft, became highly elaborate during the Classic period (600-900 AD), particularly in the kingdom of Palenque, and usually show the head of the jaguar deity of terrestrial fire in front. In Post-Classic Yucatán, particularly in the capital of the kingdom of Mayapan, censers were found in great numbers, often shaped as an aged priest or deity.
In the Eastern Orthodox Church, the Oriental Orthodox Church, as well as the Eastern Catholic Churches, censers (Greek: thymiateria) are similar in design to the Western thurible. This fourth chain passes through a hole the hasp and slides in order to easily raise the lid. There will often be 12 small bells attached to the chains, symbolising the preaching of the Twelve Apostles, where one of the bells has been silenced to symbolize the rebel Judas. In some traditions the censer with bells is normally used only by a Bishop. Before a deacon begins a censing, he will take the censer to the priest (or the bishop, if he is present) for a blessing. The censers, charcoal and incense are kept in the diaconicon (sacristy) Entrance with the censer at Great Vespers.
The censer is used much more frequently in the Eastern churches: typically at every vespers, matins, and Divine Liturgy, as well as pannikhidas (memorial services), and other occasional offices. If a deacon is present, he typically does much of the censing; otherwise, the priest will perform the censing. Unordained servers or acolytes are permitted to prepare and carry the censer, but may not swing it during prayers. Liturgical Censing is the practice of swinging a censer suspended from chains towards something or someone, typically an icon or person, so that smoke from the burning incense travels in that direction. Burning incense represents the prayers of the church rising towards Heaven. One commonly sung psalm during the censing is "Let my prayer arise in Thy sight as incense, and let the lifting up of my hands be an evening sacrifice." When a deacon or priest performs a full censing of the temple (church building), he will often say Psalm 51 quietly to himself.
In addition to the chain censer described above, a "hand censer" (Greek: Κατσί katzi or katzion) is used on certain occasions. This device has no chains and consists of a bowl attached to a handle, often with bells attached. The lid is normally attached to the bowl with a hinge.
In Greek practice, particularly as observed on Mount Athos, during the portion of Vespers known as "Lord, I cry unto Thee" the ecclesiarch (sacristan) and his assstant will perform a full censing of the temple and people using hand censers.
Some churches have the practice of not using the chain censer during Holy Week, even by a priest or bishop, substituting for it the hand censer as a sign of humility, repentance and mourning over the Passion of Christ. They return to using the chain censer just before the Gospel reading at the Divine Liturgy on Great Saturday.
Some Orthodox Christians use a standing censer on their icon corner (home altar).
In the Latin Rite of the Catholic Church and some other groups, the censer is often called a thurible, and used during important offices (benedictions, processions, important Masses). A common design for a thurible is a metal container, about the size and shape of a coffee-pot, suspended on chains. The bowl contains hot coals, and the incense is placed on top of these. The thurible is then swung back and forth on its chains, spreading the fragrant smoke.
A famous thurible is the Botafumeiro, in the cathedral of Santiago de Compostela. Suspended from the ceiling of the cathedral, the swinging of this 5-foot (1.5 m) high, 55 kilogram silver vessel is an impressive sight.
One of the explanations for the great size of the Botafumeiro is that in the early days it was used to freshen the air in the cathedral after being visited by droves of travel-weary pilgrims. It was also once believed that the incense smoke guarded against contracting the many diseases that plagued the populace in past centuries.
Hindus have traditionally used an earthen censer called a Dhunachi for burning incense with coal, though coconut husk is also used. The vessel has a flared shape with a curved handle and an open top. There are also brass and silver versions.
