The 8-inch units range from 2,000 to 2,700 watts. These units reach extreme temperatures and stay hot for several minutes after the unit is turned off. Glass ceramic top ranges have heating elements that are hidden under a smooth glass top. These may be radiant or halogen induction elements. There are no crevices to collect dirt or grease, and spills can be readily wiped up.
Some surfaces show smudges easily.
These range tops require the use of flat-bottom utensils. The range top will heat and cool more slowly than a conventional range. They may also need special cleaning and care to avoid scratching or discoloration. Sugary spills must be cleaned up promptly. Quartz halogen heating elements are designed to heat up rapidly.
