Cooking Utensils for Radiant Elements
Each cook has his or her own preference for the particular cooking utensils that are most
appropriate for the type of cooking being done. Only certain types of glass,
glass/ceramic, ceramic, earthware, or other glazed utensils are suitable for glass cooktop
use without breaking due to the sudden change in temperature. This is a matter of
personal choice. As with any cookware, yours should be in good condition and free from
excessive dents on the bottom to provide maximum performance and convenience.

elements.
