Enamel quality and type are exceptionally important for the oven and its operation. SilverMatte is a highly resistant and strong material that can stand extreme heats, even pyrolytic cleaning at 500 °C. Free from micro pores, it coats oven surfaces and baking trays, making them resistant to the highest temperatures, microwaves and steam. The triple coating of the interior supports heat reflection and provides additional insulation. Therefore, the oven interior always stays sterile and safe.
