The triangular Drip Tray is included with every Flat Top order for glass ceramic stoves. It is made from stainless steel and is dishwasher safe. Many customers purchase a second drip tray to make sure a clean one is always at the ready when it's time to start cooking. The triangle Drip Tray is designed specifically to fit between the oversized front circular heating elements common on smooth electric stoves without touching them. This prevents the stove from heating the Drip Tray during use.
