A ceramic cooktop is a flat, glassy-looking type of stovetop that sits on top of internal heating coils. The heating coils transfer heat through the ceramic cooktop, then the cooktop transfers the heat to pots, pans and cooking utensils.
Ceramic cooktops are typically etched with circles or decorative elements to mark the location of the internal heating coils. These smooth cooktops are often made of a durable ceramic-glass blend. The mix of glass and ceramic is better-suited to high heat and rapid temperature changes.
However, ceramic cooktops are susceptible to scratches, cracks and shattering from improper use. Cast iron, ceramic or unsteady pots may scratch the surface. To prevent shattering, users should avoid slamming pots or placing non-cooking objects on the cooktop.
