Abstract: A cooking apparatus top plate includes a glass ceramic substrate having a chemically strengthened uneven structure with an average surface roughness Ra of 0.1 to 1.0 μm. A cooking vessel is placeable on the top plate to be heating by the cooking apparatus. A method for processing a glass ceramic substrate includes forming a top surface to have an uneven structure and chemically strengthening the top surface that has the uneven structure. An induction heating apparatus includes a cooking apparatus top plate and a plurality of induction heating coils for heating the cooking vessel placed on the top plate.

Abstract: A ceramic glass for cooktop includes a glass material having an uneven layer formed on an upper surface of the glass material. A color difference meter value L of the ceramic glass ranges from 90 to 100. The glass material includes Li2O, Al2O3, and SiO2. A heat shock temperature of the ceramic glass ranges from 525° C. to 575° C. The ceramic glass implements a surface roughness Ra of 0.1 μm or less and surface roughness Rz of 0.8 μm or less through a polishing operation. The surface roughness Ra corresponds to an average length between at least one peak of the uneven layer and at least one valley of the uneven layer. The surface roughness Rz corresponds to a vertical distance between the at least one peak of the uneven layer and the at least one valley of the uneven layer.
