It is a very important agent to make pink and red glass. When used together with cadmium sulfide, [9] it yields a brilliant red color known as "Selenium Ruby". Pure metallic copper produces a very dark red, opaque glass, which is sometimes used as a substitute for gold in the production of ruby-colored glass.
The simplest cane, called vetro a fili [3] (glass with threads) is clear glass with one or more threads of colored (often white) glass running its length. It is commonly made by heating and shaping a chunk of clear, white, or colored glass on the end of a punty, and then gathering molten clear glass over the color by dipping the punty in a ...
Cobalt glass—known as "smalt" when ground as a pigment—is a deep blue coloured glass prepared by including a cobalt compound, typically cobalt oxide or cobalt carbonate, in a glass melt. Cobalt is a very intense colouring agent and very little is required to show a noticeable amount of colour.
Painted glass refers to two different techniques of decorating glass, both more precisely known by other terms. Firstly, and more correctly, it means enamelled glass , normally relatively small vessels which have been painted with preparations of vitreous enamel , and then fixed by a light firing to melt them and fuse them to the glass surface.
The enamels leave a layer of glass projecting very slightly over the original surface, the edges of which can be felt by running a finger over the surface. Enamelled glass is often used in combination with gilding, but lustreware, which often produces a "gold" metallic coating is a different process. Sometimes elements of the "blank", such as ...
The colored glass is crafted into stained glass windows in which small pieces of glass are arranged to form patterns or pictures, held together (traditionally) by strips of lead, called cames or calms, and supported by a rigid frame. Painted details and yellow stain are often used to enhance the design.
Gold leaf or colored enamels also can be inlaid to highlight the designs. The Leptat technique allows the glass to reflect light from many surfaces, like a jewel-cut gem. Mold etching In the 1920s a mold-etch process was invented, in which art was etched directly into the mold , so that each cast piece emerged from the mold with the texture ...
Glass bead making has long traditions, with the oldest known beads dating over 3,000 years. [1] [2] Glass beads have been dated back to at least Roman times. Perhaps the earliest glass-like beads were Egyptian faience beads, a form of clay bead with a self-forming vitreous coating. Glass beads are significant in archaeology because the presence ...
