The Hard Strong Series: Stackable Tumblers & Cylinder Glassware

Durable, attractive glassware is a must. Toyo-Sasaki Glass from Japan fits that bill. And it brings even more to the table: a storied history.

It’s a merger of two distinctive Japanese design icons: Toyo Glass, founded in 1878 during the Meiji era; and Sasaki Glass Co., founded in 1902. The two esteemed companies came together as one to form Toyo-Sasaki Glass in 2002.

Toyo-Sasaki Glass requires that each of its artisans has at least 15 years of glass-making experience and are accepted by the Certified Traditional Japanese Craft-Masters, an association that credits prestigious artisans for their ability and expertise.

There are two major strengthening methods for glassware, Physical Toughening (by heating and rapid cooling) and Ion-Exchange (by submerging in a salt bath that alters the chemical structure of the glass). Both methods temper the glass by creating a compressive stress layer on the glass surface which results in a much stronger surface.

Toyo-Sasaki’s premium grade Hard Strong Series is made with Ion-Exchange Toughening and features a cold-cutting sheer rim finish. Ion Toughening allows for a thinner glass profile that is stronger, clearer and more durable. Their signature Hard Strong Series has been used in the catering and restaurant industry for over 40 years and was awarded the prestigious Good Design Award.
