Urns are a type of container that have been used for centuries to store and transport items. They are often made of ceramic, metal, or glass and can be ornately decorated. The term 'urns' is also used to refer to two other types of containers: VASES and EWERS. VASES are typically tall and slender and are used to hold flowers or other decorative items. EWERS are usually wider and more shallow than VASES and are used to hold liquids. Both VASES and EWERS are often made of ceramic or metal and can also be ornately decorated.
