Blue Tiffany Favril Elephant Foot Vase

• 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.
