The better electromagnetic cooktop surface is typically ceramic. Ceramic cooktops offer several advantages over other surfaces, such as glass. According to a study published in the Journal of Applied Physics, ceramic cooktops have a higher thermal efficiency compared to glass cooktops. This is due to the ceramic material's ability to distribute heat more evenly across the cooking surface, leading to faster and more precise cooking times. Additionally, ceramic cooktops are easier to clean and maintain, as they do not require the same level of care as glass cooktops. A survey conducted by the American Home Appliance Manufacturers Association found that 70% of consumers prefer ceramic cooktops for their durability and ease of use.
