JSG Oceana Glass LLC is a part of Jeannette Specialty Glass, founded in 1904. They are a corporation with a long history in the heart of America's glass making region. Over a century of excellence has earned JSG a reputation for manufacturing the highest grade of commercial and industrial glass products.
In 1976, JSG began to specialize in the uses of borosilicate glass, an engineered glass durable enough to withstand a variety of mechanical, chemical and thermal shocks. Jeannette Specialty Glass perfected its own formulation, known as "Hard Roc" glass, which was the birth of JSG Oceana's distinctive glass product lines.
