Glass blank

[1] Types of decoration include cutting, engraving, acid-etching, gilding, and enameling.

Often the term blank is used in reference to an uncut piece of glass that will be cut or engraved.

A cased glass blank is an object made with several layers of colors.

Figured blanks are made when hot glass is blown into a mold.

While the molded shape is considered part of the decoration, additional details are often added after the glass is cooled.

The Portland Vase at The British Museum is an example of a piece of glass created using a cased glass blank.
