Probably a stupid question / Silgranit II sink
Looking at the Blanco Cascade in black.
These sinks are supposed to be great: Don't scratch, color goes all the way through, can't burn 'em, etc., etc., etc. I'm thinking I want one. But, if they're so solid and can't be harmed . . . why do they sell a protective stainless steel grid fitted to the bottom of the sink?
