Flashed glass is composed of one (single) or two (double) thin (flashed) layers
of a darker color on a clear or light colored base glass. Because of the thin flash layer, the appearance of a sheet can vary from an even and uniform appearance, to a subtle gradation from light to dark, to
an abrupt and dramatic interruption of color.When two different colors are flashed together, a rich third color results. An example is a red on selenium yellow glass, in which the changing
thickness of the red flash creates a shaded orange color with the yellow below. Another example is a cobalt blue on medium green glass, in which the shaded areas create a turquoise color. The
variations of flashed glass add a dimension to the stained glass palette that is both subtle and striking. Through the careful use of the light and dark areas within a sheet of flashed glass, a rich spatial
sense can be achieved. Flashed glass is often used for acid etching and sandblasting. These processes create graphic designs by selectively etching away the flashed layer to reveal the contrasting base
below. |
