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