Abstract
There is disclosed a stove, with a smooth-top cooktop, for cooking food, the stove comprising: a stove body; a smooth-top cooktop to cook food thereon; and at least one heat source disposed adjacent to a cooking surface of said cooktop. The cooktop comprises glass ceramic with an upper layer and an inner layer, with the upper layer comprising a different glass ceramic material than the inner layer. The upper layer is configured to minimize surface defects such as fissures, cracks, pits, and pores. The inner layer is configured to provide resistance to impact to the upper layer from cooking utensils being dropped onto the upper layer of the smooth-top cooktop, and at least the inner layer of the glass ceramic being configured to obscure visibility of the at least one heat source, through the upper layer of the glass ceramic.
