Range - Cookware Used on a Radiant Smooth Glass Cooktop
The type of cookware you use on a radiant cooktop can affect how it performs. We recommend using medium or heavy-weight cookware.
Flat Bottom pans are essential for good cooking performance since the bottom of the pan needs to touch the glass for the best heat transfer. Most current brands sold today have flat bottoms. Much older, used cookware and/or thinner cookware will show signs of no longer being flat. Non-flat pans may crack the glass. See Steps to Check Cookware for Best Performance.
Here are our suggestions for the proper type of cookware to use on radiant glass cooktops:
Stainless Steel is highly recommended. A sandwich-clad bottom is especially good because it combines the durability and stability of stainless steel with the heat conduction and distribution of aluminum or copper.
Heavy-Weight Aluminum cookware is also recommended. It conducts heat faster than other metals and cooks evenly. Aluminum residue sometimes appears as scratches on the cooktop, but these can be removed if cleaned immediately.
Copper Bottom pans are also good, but they can leave residues on the cooktop that appear as scratches. These can be removed if cleaned immediately, but do not let a copper-bottom pan boil dry. An overheated copper pot will leave a residue that will permanently stain the cooktop.
Porcelain/Enamel pans give good performance only if they have a thick, flat bottom. Avoid boiling these pans dry, as porcelain can melt and fuse to the surface.
Glass or Ceramic cookware is not recommended. These pans may scratch the surface. Glass is a poor conductor of heat so cooking times will be longer and they may require constant attention during cooking.
Stoneware is not recommended. It may scratch the surface and will give poor performance.
Cast Iron cookware is not recommended. If the cookware has a burr or rough spot, it will scratch the glass surface. Additionally, it is slow to absorb heat. Once this type of cookware heats up, especially on high heat, it holds an intense amount of heat which is transferred to the cooktop. This can cause the element to shut down as a response to the temperature limiters which indicate surface temperature is too high for cooktop components to handle.
Porcelain Coated Cast Iron cookware is okay as long as the cookware is covered completely with porcelain enamel. Caution is recommended when using cast iron cookware that is not completely covered with smooth porcelain enamel, as it may scratch the glass ceramic cooktop. Additionally, if used at high heat for a long period, it will hold heat as described for plain cast iron and the heating element could shut down in response to the temperature limiters which indicate surface temperature is too high for cooktop components to handle.
Carbon Steel cookware is okay as long as the cookware has a flat bottom and is smooth to prevent against scratching.
Titanium cookware has tested well on ceramic cooktops. Ceramic titanium is a non-stick finish applied to a base metal. We tested one with aluminum as a base metal.
