Spectrum Glass

Spectrum Glass manufactures specialty sheet glass for lighting, architecture, and stained glass arts. With a unique combination of traditional handcrafted methods and modern technology, Spectrum produces a modern art glass that has set new standards for quality and consistency. Sheet sizes are 24” x 48”, Water glass is 21” x 48”. Closed cases contain approx. 464 sq. ft. or 58 sheets. Baroque glass is a modern version of mouth-blown “reamy” glass. By slowly stirring together glasses of carefully mismatched compositions, a “conflict” is created that manifests in a dimensional swirling texture and vivid color contrast. Wispy opalescents are composed of half cathedral glass and about half opaque white glass. The white opal is hand-ladled into a moving stream of cathedral color. The two glasses are then stirred together, by hand, just before the sheet is formed. In the finished sheet, wisps of opal display as both surface variegation and internal shadowing, generating reflection and depth.

Near opposites of their wispy cousins, Semi translucent opalescents are primary opal glass eliminating the perception of images through the sheet. Because of their relative opacity, these glasses are highly reflective in nature. With natural or artifical backlighting they reveal a captivating luminescent glow. Translucent opals are about half cathedral color and half white opal glass. The larger proportion of opaque white reduces light transmission and increases surface reflection. Some translucents involve multiple cathedral colors with white, and others use colored opals to achieve their individual character. Artique is a recreation of the character of mouth-blown antique glass. The texture is scribed into the surface of the glass while the sheet is still extremely pliable and hot. Waterglass is a natural surface created by stretching the sheet while it is still hot and in a pliable state. The result is gentle, rolling waves that resemble the surface of a lake or stream. The stretching process also renders a highly pristine surface and a slightly narrower sheet. Cathedral colors are single color glasses, with very slight, irregular surface texture. Degree of light transmission is directly related to the density of color; clear glass is highly transparent, black glass is completely opaque.
