Abstract

A ceramic pot for electromagnetic over is composed of pot body and pot bottom, and features that on the lower surface of said pot bottom there is a film layer of 0.3-0.9 mm in thickness, which contains Ag, Cr and Fe. Its advantages are high thermal efficiency and high insulating performance.

Description

technical field [0001] The invention relates to a cooking utensil, in particular to a ceramic pot used in an electromagnetic oven and a process for baking an iron film on the glaze on the outer bottom thereof. Background technique [0002] Because of its obvious advantages of energy saving, high efficiency, safety, environmental protection, convenience and practicality, induction cooker is accelerating its entry into ordinary family kitchens and catering industries. Regrettably, as the supporting pan of induction cooker, it is designed according to the cooking habit of western food, generally all is metal products, made of stainless steel, cast iron. However, as far as the Chinese are concerned, their cooking habits prefer to cook slowly. The stewed soup tastes delicious and is a good nourishing product. However, ordinary ceramic pots (casserole) are insulated and cannot accept the magnetic field lines emitted by the induction cooker, and cannot form...
