Abstract
Surface-decorated utensil includes a ceramic ware and a plurality of decorative laminar elements of noble metal on its surface. As an alternative, the spacing between neighboring laminar elements is not less than 0.2 mm and the maximum length of each laminar element is not more than 8.5 mm. As another alternative, the spacing between neighboring laminar elements is not less than 10 mm and the maximum length of each laminar element is not more than 12 mm. In addition, the laminar elements are coated with a frit layer. The surface-decorated utensil is not damaged when used in an electronic range, while it is superior in chemical durability and coloration.
