The differences between glass cook tops and traditional gas or electric surfaces do not stop at appearance. The smooth surface of a ceramic cook top requires specific care and maintenance to keep it in optimal condition. Glass surfaces, unlike older-style cook tops, are prone to cracking and breakage if they are not treated properly. Understanding the risk factors for cracking is the first step to protecting your surface from damage.
Glass cook tops are susceptible to damage from certain types of cookware. Heavy-duty aluminum, enameled cast iron, stainless steel and copper-bottom cookware are suitable choices for your glass range. Ensure that the bottoms of your cookware are smooth and free of any rough edges that can scratch the glass. Cookware such as porcelain, stone, ceramic and traditional cast iron are not recommended on glass surfaces as they can scratch and damage the surface. Over time, scratches and damage can weaken the surface and cause it to crack.
Like most forms of glass, ceramic cook top surfaces are vulnerable to impact damage. Do not drop your cookware on the surface. The weight of the cookware will crack the surface. Cookware should be lifted carefully, even when moving from a burner to another area of the surface. Do not slide your cookware across the surface.
Always place your pan on the cook top before turning on the heat. Placing a hot pan on a cold glass surface creates a thermal shock that can cause the surface to crack. Never place hot pans from the oven or microwave on the glass surface, even on pot holders or hot plates.
Select the proper burner size for the radius of the pan that you choose. Placing a large pan on a smaller burner will leave the cook top struggling to maintain the appropriate heat level. As a result, the surface will overheat, which can potentially create a stress fracture from the heat intensity.
