It wasn’t so long ago that Western Pennsylvania was abundant with glass manufacturers. But as industrialization slowly diminished from the region, many of these manufacturing facilities grew cracked and shattered, leaving only stories and memories of past glass companies. Only a handful of companies stood up to the test of those times, and out of these, only one is a master of borosilicate glass. That is us, Jeannette Specialty Glass/JSG Oceana.

Our parent company name, Jeannette Specialty Glass, mirrors our mission and our business: we are glass specialists. Specifically, our focus is on “Hard Roc” glass, our patented borosilicate glass that gives JSG its unique placement in the industry. We have the ability to offer an array of colorations that are guaranteed to remain as beautiful as the day they were made –our glass is scratch, stain, chemical, and thermal shock (heat) resistant. Many of our customers find that our “Hard Roc” glass becomes an integral component in their finished products.

For those who want to get their hands on our “Hard Roc” glass, we have made it as accessible as possible through our company’s four divisions: JSG Industrial Division (where our glass is available as lenses, refractors, and reflectors), JSG Private Label (the glass is available in the styles of blender jars, pedicure basins, and goblets), JSG Oceana Kitchen and Bath (where you can find glass bathroom sinks and get the only functional glass kitchen sink in the world!), and, finally, JSG Oceana Giftware and Tabletop (your dinnerware and serving pieces). It’s more than clear to us: Jeannette Specialty Glass and our premier products are the “roc” solid choice when it comes to choosing the right glass for your application.

We would love to show you some examples of our work! Visit our websites today, at and, and don’t forget to come back next month for our next blog update!
