About Jeannette Specialty Glass

Our History

JSG LogoJeannette Shade & Novelty, Jeannette Specialty Glass's parent company was founded in 1904. We are a corporation with a long history in the heart of America's glass making region.

A century of excellence has earned JSG a reputation for manufacturing the highest grade of commercial and industrial glass products. In 1976, Jeannette Specialty Glass began to specialize in the uses of borosilicate glass, an engineered glass durable enough to withstand a variety of mechanical, chemical, and thermal shocks.

In time, Jeannette Specialty Glass perfected its own formulation, known as "Hard Roc" glass, which we continue to manufacture to this very day.  While many glass manufacturers offer reflector and refractor lenses, commercial glass and industrial mold work, no one can replicate the Clear Colorless Glass (not green) produced by JSG and our attention to quality control standards.
