Pair of Wedgwood Black Basalt Engine-Turned Urns

• Basalt - Basalt is a hard, dense volcanic rock formed from the rapid cooling of basaltic lava, and makes up most of the earth's oceanic crust.
  
  However it is also the name given by Josiah Wedgwood in 1768 to a fine black unglazed porcelain which he called Wedgwood Black Basalt.
  
  Using this fine-grained stoneware he was able to produce copies of the newly excavated Etruscan pottery from Italy, with a lustrous and smooth, surface, and this new innovation proved to be a huge commercial success.
• Engine Turned - Engine turning is a decorative technique used on metal surfaces to create intricate curving or geometric pattern. The process involves cutting a series of lines into the surface of the metal using a rose engine or decoration lathe which rotates the metal as it cuts, allowing the operator to create a repeating pattern that covers the entire surface. The resulting surface has a shimmering, reflective quality that is often described as "engine turned." Where an engine turned item has been enamelled, the term used to describe the decoration is usually guilloche.
  
  Engine turning was originally developed to decorate metal objects such as firearms, scientific instruments, and other metal objects that required precise and elegant design.
