Why does it take a glass or ceramic cooktop so long to cook food or boil water?
You have to use cookware that has a flat, smooth bottom. The heat conducts up through the cooktop to the cookware. If the cookware isn’t flat, the limiter may tell the element to shut down to prevent any overheating damage. If you have a smooth cooktop with the elements under translucent glass, you can still see the red glow as the elements cycle on and off to maintain the desired heat setting. Elements in the smoothtop don’t respond as quickly to changes in the heat setting as do regular coil elements. You should start out with lower heat settings and gradually increase the heat setting until you have the desired heat. It is very important to use heavy gauge, smooth, flat-bottomed pans when cooking on a smoothtop cooking surface. This is because the cooking heat transfers by conduction, and if the pan isn’t flat, the heat won’t transfer very well. Furthermore, the cooktop has sensors to detect when uneven heating is occurring, and will cycle the elements off and on to protect them fro
