Cast-iron, ceramic and stoneware pieces are not recommended for use with ceramic stovetops because those pieces have rough, unfinished bottoms that easily scratch the stove's surface. Pots and pans with rounded edges also are not recommended because they fail to heat evenly on the flat burners.
Copper cookware can be used with a ceramic stovetop, but the pans often leave a residue that must be cleaned immediately after use. To avoid scratches, all cookware should be lifted, rather than dragged, when moving the pieces across the stovetop. It is also important to keep cookware bottoms free of buildup, because grease can leave permanent marks on the burners. Stainless steel, heavy aluminum and titanium cookware are recommended for use with ceramic stovetops.
