Abstract
A food holding cabinet having one or more food-holding compartments has two or more zones in a compartment, wherein holding temperatures can be different from each other. A shelf made of glass-ceramic passes infrared energy from two or more heating elements attached to the glass-ceramic shelf. Energy emitted from the different heating elements effectuate different temperatures of localized regions of the glass-ceramic and impart different amounts of heat energy into a food item or food holding trays above the heating elements.
