Research notes Zwiesel Glas makes its machine-made Tritan crystal glasses in its own glassworks in Zwiesel, Germany, and labels them Made in Germany; the company says it has about 800 staff across Zwiesel and its own glass factory in Hungary, where handmade series are made. The shares by country are rough: Zwiesel is the main site. Its parent, Zwiesel Fortessa, added the Eisch glassworks in October 2025. It publishes no sustainability report, supplier code, audit results or wage data, and only its environmental work (oxyfuel furnaces) is described.
