Glass consisting of a layer of clear glass fused to a layer of opal or other tinted glass. Cased glass transmits light more efficiently than opal, with more luster and better diffusion. Cased glass can be blown or molded.
when one layer of glass is inside another
glassware made of two or more layers of different colored glass. The process involves first making an outer casing by blowing a gather, knocking off one end, and opening the piece to form a cuplike shell. This shell is then placed in a metal mold and a second, different colored gather is blown into it. This combined piece is taken from the mold and reheated to fuse the two layers together. The outer layer is thick, which distinguishes it from the thin outer layer of flashed glass. This term is also improperly used in place of flashed or overlay to imply one layer of glass over another.
Glassware which is composed of two or more layers of colored glass. The inner layer may be blown into outer layers while the glass is still hot or a piece in one color may be dipped into the molten glass of another color while it is hot. Cameo glass (see above) is a form of cased glass and Victorian satin glass is also often cased.
A layer of glass that is applied over a contrasting color, so that the surface can be carved, cut, or acid etched to reveal the underlying layers and colors.
Cased glass is made up of two or more layers of different colored glass. Patterns are cut into the outer layer so that the layer beneath is visible. This was produced by the Romans initially.
One layer of glass, often colored, sandwiched between two plain glass layers or vice versa, the outer layer engraved to create a decorative effect. This is an ancient technique revived in the 19th century.
Glass formed by layering glass of varying colors together. Usually two colors, sometimes more. In founts, it is often wheel cut to produce geometric designs. Sometimes referred to as "overlay."
Blown glass that has two or more layers of different colors. The upper layers may be etched or sandblasted to reveal the glass underneath.
