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.
