JSG Oceana is a subsidiary of Jeannette Specialty Glass, 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 quality of commercial, industrial, and residential glass products. In the 1990’s JSG began to specialize in the use of borosilicate glass, an engineered glass durable enough to withstand a variety of mechanical, chemical, impact, and thermal shocks. Jeannette Specialty Glass perfected its own formulation, known as “Hard Roc” glass and diversified its production capabilities to offer innovative and artful glass sinks, tile, and bakeware. Our product line continues to grow each year with all JSG Oceana glass products being produced in the USA by our skilled and dedicated American workforce.
