Will it shatter? Testing cooktop durability with a steel ball

This post is part of our “Tough as Glass” series.

Accidents happen. In the kitchen, slippery hands, hot handles, and any number of distractions can cause even the most experienced home cooks to drop heavy cans, cookware, and utensils.

Since the cooktop is the epicenter of the kitchen, it often bears the brunt of these mishaps. Yet, even under the most difficult demands, cooktops are counted on to safely generate heat without breaking after an accidental drop.

To ensure our cooktops stand up to the impacts they might face in the kitchen, we drop a steel ball, weighing in at 535 grams (1.18 pounds), directly onto the cooking surface from a height of nearly two feet. That’s like dropping a can of soup from the cabinet above the stove. Watch what happens when SCHOTT scientists pummel a glass-ceramic cooktop with a solid steel ball:



No breakage. No cracks. No dents. By passing this ball-drop test, a SCHOTT CERAN® cooktop meets a set of UL standards required for household ranges. Just as importantly, it means the cooktop will continue evenly heating pots and pans after the drop of a can or pot, allowing home chefs to perfectly cook their favorite meals.

What questions do you have about how your cooktop is tested? Stay tuned for more videos that show how we put glass to the test.
