    摘要: A cooking appliance (100) includes a glass-ceramic substrate (110) with a top surface (112) for receiving cookware thereon for heating. The surface (112) includes a coating formed by applying a sol-gel coating (120) after the surface is roughened to increase the surface roughness of the top surface (112) and improve adhesion of the coating (120) thereon. The sol-gel coating (120) forms a matte finish on the cooking appliance (100) while having anti-stick properties for cleanability.
