Julio Santos Australia Red Sommerso Glass Vase, Engraved 1999

• Sommerso - A method of making cased glass developed in Murano in the 1930s, where one or more layers of transparent coloured glass is encased within a layer of thick clear colourless glass.
• Engraved Glass - The method of decorating glass by marking the surface with a sharp intrument such as a diamond, metal needle or rotating cutting wheel. As pressure is applied to the surface, best results for engraving are achieved if the glass is of sufficient thickness. In the 19th century etching was used to decorate some table glassware that was too fine to take an engraving tool.
