Opal and Gilt Vases with Bohemian Enamel Glass Vase

• Cased Glass - Cased glass is a type of glassware that is made by sandwiching a layer of one colour of glass between two layers of another colour of glass. This technique is also known as "slip-casting" and "slip-decorated" or "overlay" glass. The process creates a decorative effect by contrasting the colours of the outer layers with the inner layer. The outer layers can be clear, opaque or coloured and the inner layer can be a different colour, or it can be left clear to create a more subtle effect.
  
  The technique was first developed in the 19th century, primarily in Europe, and it was used to produce a wide range of decorative glassware such as vases, bowls, and bottles. Cased glass was particularly popular during the Art Nouveau period, when many glassmakers, including Loetz, Galle, Steuben and Tiffay began to experiment with different colours and designs to create unique and striking pieces of glassware.
• Opal Glass - Opal glass, also known as milk glass, is a type of opaque glass that is usually white or cream-colored, with a slightly translucent appearance resembling opal. It is produced by adding various materials to the glass during the manufacturing process, such as tin, fluorides, or phosphates, which give it its characteristic milky appearance.
  
  Opal glass has been used for centuries in the production of decorative objects, such as vases, lamps, lamp shades and figurines. It was particularly popular in the 19th century in Europe, where was used by glass makers such as Lalique.
  
  Opal glass is still used today in the production of a wide range of decorative and functional objects, including lampshades, jewelry, and kitchenware. Its milky appearance gives it a timeless, elegant look that is popular with collectors and enthusiasts of antique and vintage glassware.
