DESC: White or Bisque with Black Control Panel and Black Patterned Glass-Ceramic Cooktop. The Patterned Glass-Ceramic Stove Cooktop is built to last. It is not ordinary glass, but a highly engineered "glass ceramic" material that is impact- and stain-resistant. The decorater pattern is actually part of the stove cooktop; therefore, it will not wear off under normal use. The pattern also helps to hide smudges.
