Your new range has a radiant glass cooktop. If you are
used to cooking with gas burners or electric surface
units, you will notice some differences when you use
the radiant cooktop.
The best types of cookware to use, plus heat-up and
cool-down times, depend upon the type of burner or
surface unit you have.
The following chart will help you to understand the
differences between radiant cooktops and any other
type of cooktop you may have used in the past.
