An urn is a vase, often with a cover, with a typically narrowed neck above a rounded body and a footed pedestal. Describing a vessel as an "urn", as opposed to a vase or other terms, generally reflects its use rather than any particular shape or origin. The term is especially often used for funerary urns, vessels used in burials, either to hold the cremated ashes or as grave goods, but is used in many other contexts; in catering large vessels for serving tea or coffee are often called "tea-urns", even when they are metal cylinders of purely functional design. Large sculpted vases are often called urns, whether placed outdoors, in gardens or as architectural ornaments on buildings, or kept inside.
Funerary urns (also called cinerary urns and burial urns) have been used by many civilizations. After death, corpses are cremated, and the ashes are collected and put in an urn. Pottery urns, dating from about 7000 BC, have been found in an early Jiahu site in China, where a total of 32 burial urns are found, and another early finds are in Laoguantai, Shaanxi. There are about 700 burial urns unearthed over the Yangshao (5000-3000 BC) areas and consisting more than 50 varieties of form and shape. The burial urns were used mainly for children, but also sporadically for adults.
The Urnfield culture (c. 1300 BC - 750 BC), a late Bronze Age culture of central Europe, takes its name from its large cemeteries of urn burials. The discovery of a Bronze Age urn burial in Norfolk, England, prompted Sir Thomas Browne to describe the antiquities found. He expanded his study to survey burial and funerary customs, ancient and current, and published it as Hydriotaphia or Urn Burial (1658).
In ancient Greece, cremation was usual, and the ashes typically placed in a painted Greek vase. In particular the lekythos, a shape of vase, was used for holding oil in funerary rituals. Romans placed the urns in a niche in a collective tomb called a columbarium (literally, dovecote). The interior of a dovecote usually has niches to house doves. Cremation urns were also commonly used in early Anglo Saxon England, and in many Pre-Columbian cultures.
In some later European traditions, a king's heart, and sometimes other organs, could be placed in one or more urns upon his death, as happened with King Otto of Bavaria in 1916, and buried in a different place from the body, to symbolize a particular affection for the place by the departed.
In the modern funeral industry, cremation urns of varying quality, elaborateness, and cost are offered, and urns are another source of potential profit for an industry concerned that a trend toward cremation might threaten profits from traditional burial ceremonies.Biodegradable urns are sometimes used for both human and animal burial. They are made from eco-friendly materials such as recycled or handmade paper, salt, cellulose or other natural products that are capable of decomposing back into natural elements, and sometimes include a seed intended to grow into a tree at the site of the burial.
Besides the traditional funeral or cremation ashes urns, it may also be possible to keep a part of the ashes of the loved one or beloved pet in keepsake urns or ash jewellery, although this might be banned in some localities as the law of certain countries may prohibit keeping any human remains in a private residence. It is even, in some places, possible to place the ashes of two people in so-called companion urns. Cremation or funeral urns are made from a variety of materials such as wood, nature stone, ceramic, glass, or steel.
Scattering of ashes has become popular over recent decades. As a result, urns designed to scatter the ashes from have been developed. Some are biodegradable, and some recyclable after being used. Some cremation urns have been made out of wood.
A Figural urn is a style of vase or larger container where the basic urn shape, of either a classic amphora or a crucible style, is ornamented with figures. These may be attached to the main body, forming handles or simply extraneous decorations, or may be shown in relief on the body itself.
A tea urn is a heated metal container traditionally used to brew tea or boil water in large quantities in factories, canteens or churches. They are not usually found in domestic use. Like a samovar it has a small tap near the base for extracting either tea or hot water. Unlike an electric water boiler, tea may be brewed in the vessel itself, although they are equally likely to be used to fill a large teapot.
In Neoclassical furniture, it was a large wooden vase-like container which was usually set on a pedestal on either side of a side table. This was the characteristic of Adam designs and also of Hepplewhite's work. Sometimes they were "knife urns", where the top lifted off, and cutlery was stored inside. Urns were also used as decorative turnings at the cross points of stretchers in 16th and 17th century furniture designs. The urn and the vase were often set on the central pedestal in a "broken" or "swan's" neck pediment. "Knife urns" placed on pedestals flanking a dining-room sideboard were an English innovation for high-style dining rooms of the late 1760s. They went out of fashion in the following decade, in favour of knife boxes that were placed on the sideboard.
