I took the following information from  Google  –  ARCOROC brand glassware

             Arques, France

“”Arcoroc is a brand name used by Arc International (headquartered in Arques, France) primarily for their commercial-grade ware (glassware made to withstand heavier abuse than items sold for typical home use),  such as drinkware,  barware, cookware, serving bowls, etc, used especially in restaurants, hotels and other institutional settings.  The brand name “Arcoroc” was introduced in 1963.””
