Abstract:
A stove, such as for cooking food, said stove comprising:a stove body; a cooktop; said cooktop comprising a cooking surface; at least one heat source; said at least on heat source being disposed at said cooking surface; said cooking surface being configured to receive a bottom of a cooking utensil; controls being disposed under said cooking surface of said cooktop; said cooking surface comprising a floated glass ceramic material having a surface roughness which is minimized, wherein said minimized surface roughness has an average roughness less than or equal to two hundredths of a micrometer or a square average roughness less than or equal to one hundredth of a micrometer; said surface roughness being minimized to produce an easy-to-clean surface, to minimize uneven spots to thus minimize air cushions being formed between said cooking surface and a bottom of a cooking utensil to thus maximize heat transfer between said cooking surface and a bottom of a cooking utensil, and to minimize distortion in said cooking surface to thus permit a substantially distortion-free view of said controls.
