Corning Cooktop in DC Question

[sarahperdue]

Here's a Corning cooktop in the DC area. I wanted one for years, but don't have a place for one now. I see this one is stained. Can this kind of staining be removed? Is this one pyroceram or glass?

Thanks,
Sarah

It's a nice cooktop, but I gave up on a range with one because of the staining. Perhaps the newer products like Cerama-Bryte could remove the stains, but back in the day, not much seemed to help!
