Daum French Pate de Verre Snail Dish

• Pate De Verre - A technique practiced in ancient Egypt from 1500 - 1000 BC, that was revived in France in the 1880s, pate de verre, which translates as "paste of glass", is a process in which glass is ground to a fine powder, mixed with adhesives, colouring agents and water to create a paste which is then mixed , placed into a mould and then reheated until molten.
  
  The most prolific, and therefore best known practitioners include Gabriel Argy-Rouseau, Francois-Emile Decorchement and Almeric Walter.
• Etched - Glass decorated with an etched design, which is achieved through marking out the pattern, protecting the area that is not be etched, and then immersing the object in acid to dissolve the surface of the unprotected area. With some glass objects, such as cameo glass, there may be several layers of different coloured glass, and part of the top layer is dissolved leaving the bottom layer as the background. The longer the time of exposure of the object to acid, the deeper the etching.
  
  The word etching is also sometimes used to describe another method of decoration, where wheel grinders were used decorate the surface, but this technique is usually known as engraving.
