Arcoroc was first launched in 1963 as a tempered glass brand. It developed into a generalist professional brand for the catering industry, which includes cutlery, tableware and glassware, consisting mainly of glass material (annealed glass, opal, tempered glass, Zenix) as well as complementary ranges in porcelain and stainless steel. All Arcoroc products are dishwasher safe (2000 cycles claimed). Source: Wikipedia
