Favrile Trumpet Vase with Tiffany Markings

• 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.
• Incised - A record of a name, date or inscription, or a decoration scratched into a surface, usually of a glass or ceramic item with a blunt instrument to make a coarse indentation. Compare with engraving where the surface is cut with a sharp instrument such as a metal needle or rotating tool to achieve a fine indentation.
• Knop (glass) - In Georgian glassware, the knop is a bulbous protrusion, usually midway up the stem of the glass. It may be included singly or in groups, and may be hollow or solid. There are many styles of knop including basal, baluster, bell, acorn, cone, flattened, melon and mushroom.
