Some electric cooktops are manufactured with metal hobs with elements protruding from the metal and are available in stainless steel or white enamel finish. The heating elements can be controlled by knobs or touch controls on the surface of the cooktop. Electric cooktops are built into a countertop / benchtop and come in a variety of sizes and styles to fit different kitchen needs. The glass type cooktops are easy to clean than gas cooktops, but they may take a longer time to heat up or cool down
