The pure ceramic glass surface comes in a saturated color to give the cooktop a sophisticated appearance. This model also features our exclusive Custom Control temperature management system that allows high-speed elements to heat quickly for mixing a stir-fry or c aramelizing onions. The Custom Control temperature management system responds more like a gas burner to give you precise control from a high high boil all the way down to a melt and hold. The triple-ring element offers the versatility of using several cookware sizes on one element - whether your recipe calls for a small saucier large skillet or stockpot. The dual-ring element supports a range of cooking options for increased flexibility.
