Tiffany Harp Desk Lamp with Iridescent Shade

• Bronze - An alloy of copper and tin, traditionally in the proportions of about 9 parts of copper to 1 part of tin.
  
  The discovery of bronze in Western Asia in the 4th century enabled people to create metal objects which were superior to those previoulsy possible because of its strength and hardness, and it has been used throughout the world for weapons, coins, tools, statuary and other decorative items.
  
  It is very fluid in a molten state, and its hardness, strength when set, and non-corrosive properties makes it most suitable for casting sculpture.
• Damascene - Damascening is a technique used to decorate metal objects, such as swords, armor, and other metalwork, by inlaying different colored metals into grooves that have been etched or engraved into the surface of the metal. The technique is believed to have originated in Damascus, Syria, and was later adopted by other cultures such as the Japanese, Indians and Iranians.
  
  The process typically involves etching a design into the surface of the metal, and then filling the grooves with a contrasting metal, such as gold or silver. The inlaid metal is then burnished to create a smooth surface, and the design is polished to a high shine. Damascening can create intricate and highly detailed designs, and is often used to decorate weapons, as well as jewellery, and other decorative objects.
• Irridescent Glass - Iridescent glass has a shimmering or rainbow-like appearance due to the way it reflects light. It is created by applying a thin layer of metal oxides to the surface of the glass while it is still hot and malleable, which then creates an interference effect that produces a range of colours as the light reflects off the surface. The exact colours and patterns created by iridescent glass depend on the specific types of metal oxides used and the techniques used to apply them.
  
  Iridescent glass was first developed in the late 19th century, and quickly became popular for use in decorative art glass and stained glass windows. Some of the most famous examples of iridescent glass were created by artists such as Louis Comfort Tiffany and his studio, who used it extensively in their distinctive lamps, vases, and other decorative objects.
  
  

• Favrile - Favrile glass is a type of iridescent art glass, similar to some of the Roman glass that has been excavated after being buried for centuries. It was developed by Louis Comfort Tiffany in 1892, patented in 1894 and the first itmes were produced in 1896. It differs from most iridescent glasses because the colour is ingrained in the glass itself, instead of being sprayed onto the surface while the glass was molten, as with Carnival glass.
  
  The most common items manufactured by Tiffany in favrile glass were vases.
  
  The glass was imitated by Loetz and other Bohemian manufacturers.
