CAMEO GLASS: A multi-layered glass which has a picture carved into it as
layers. Colored layers form the contrasts of the picture the picture is raised above the
surrounding surface. It is normally only seen as a carving where there is more than one
colored layer to the glass. Carving is done using a cutting wheel or hydrofluoric acid leaving quality cameo glass. |
| CARVED GLASS: A three-dimensional sculpture created by different carving depths in the glass thru etching and blasting the glass. |
| CALIPER: Tongs use to manipulate and control molten glass piece. |
CANE: A cross section of glass is made by pulling and stretching molten glass from both
ends. It comes in several colors, patterns and strings range from fine filament to inches in diameter. The detail will continue to hold the precise shape even when scaled down to an almost invisible dimension. |
| CARVING: Removing excess molten glass off of a working glass piece. |
| CASING: It is created when an additional layer of glass is placed over and existing layer of another color. |
| CAST GLASS: Is created by pouring molten glass into a mold. |
| CASTING: Creating a specific glass shape by pouring molten glass into a form. |
| CATHEDRAL
GLASS:
Is usually a transparent glass of one color. Various patterns may be rolled onto the glass during its manufacture to diffuse light coming through the glass. Common patterns include hammered, granite, ripple, seedy, double rolled, and rough rolled. |
CAITHNESS GLASS: Caithness Glass started in 1961 in northern Scotland as a small glassworks in 1961 making vases and bowls for the tourist trade. Today they are a major company with operations in Kings Lynn,
Oban, Perth, Oban and Wick and are part of the Royal Doulton company.
Paul Ysart, a world renowned paperweight maker and Colin Terris were recruited into the company. Paul's had very secretive paperweight techniques and Colin's developed his own completely different designs, both increasing the success of
Caithness Glass company. |
CHILL-MARK: Any instrument used on a hot glass surface there is a potential for it to
leave a cooled surface that refracts light differently and these marks are called chill
marks. |
| CHORD: Lines of clear glass with slightly different expansion coefficient enhance refract
light at different rates. |
| CHUNKED: A piece of glass that has been badly damaged. |
COLD WORKING: Any working, without heat, on the surface of a finished piece of glass
once annealing process is completed. This is often accomplished by grinding, surfacing
or drilling. |
| COLLAR: It is a ring used to hold the cane glass in place while working a piece. |
COLOR: 99% of glass color comes from Germany or Bulgaria and
transparents are all most black until actually blown into an art piece. They come into the shaped of a small
rolling pin. Opaque colors are most often the same color as before they are melted. |
| CONTEMPORARY GLASS: Glass exclusively designed by an artist to
satisfy their own creative desire. |
COPPER-FOILED: A method for creating 2 or 3-dimensional art glass from smaller pieces
of colored art glass. Thin strips of adhesive copper foil are wrapped around the edges
of each piece of art glass and then the he pieces are positioned into the designed pattern
and soldered together. The copper foil becomes hidden underneath the solder. Often
the blackened by an application of patina, chemicals. |
| CORD: Streaking to a slight color haziness normally caused by deficiencies in the glass
quality product. |
| CRACKLE GLASS: It is created by dipping a molten cylinder of glass into water which
causes the exterior of the glass to crack but the molten interior holds together. The
cylinder is sliced down the side, flattened and the crackle textures are rolled into glass. |
| CROWN GLASS: Rotating the glass as it is blown, a by product is a disk shape with a
crown, in the center. This is also called a Roundel. |
| CULLET: To assist in the glass melting process, several materials are mixed into the pit:
slag, scrap or just extra glass materials. Note: this reduces the quality of the final glass
product. |
| CUTTING: By using a consistent speed rotating wheel coated with either cloth, diamond
dust or an abrasive to grind a pattern or design into the glass. |
| CUT-TO-CLEAR: Cutting however many layers needed to create the desired effect in the glass by showing the under layers. |
| CURIOUS GLASS: It is glass that does not meet a manufacturer's specifications, rejects, an is often very unusual, unpredictable and can be ugly or beautiful. |
| CYLINDER: The glass bubble is blown into a cylinder shape and is the most common type of blown glass. The ends are cut off, the cylinder is split along its length, and finally unrolled into a flat sheet. |
