An induction range heats and cools quickly and provides more precise cooking temperatures. They may be safer and easier to clean since spillovers do not bake on. Using an induction range requires cookware made of magnetic materials, such as iron or steel. An oscilating magnetic field in the range top induces a secondary current in the pan. Gas burners usually have a grid to hold cookware.
Spills can sometimes run under the burners.
Burners that are sealed, with no area for spills to run below, or a rim around the edge to contain spills, are easier to clean. Gas cooktops may be glass, porcelain-coated steel, or stainless steel. Gas models may use a spark or electric igniter and some reignite if the flame is blown out. Some have sealed burners to keep spills contained. Gas cooktops with sealed burners or conventional burners are easier to clean than older models.
