Lalique Blue Tinted Glass Vase with Vegetation Design

• Opalescent / Opaline - The descriptions of glass as "opalescent" or "opaline" are often used interchangeably by dealers and auction houses. At the upper end of the scale, opalescent / opaline glass can refer to the opal-like milky blue glass produced by Lalique and Etling. It also refers to the pressed glass mass produced in Britain from the 1840s with a milky white edge as sugar-basins, milk jugs and vases were made in great quantities for the mass market, and were sold at fairs along with Staffordshire figures and wooden dolls. A less common type of opalescent glass was made from two layers of glass blown into a mould.
• 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.
