Abstract
Abstract A new article of manufacture is disclosed. This article includes a glass substrate having at least first and second surfaces. A coating is placed on at least a portion of one surface of the glass substrate. The coating has a thickness in a range from about 70 angstroms to about 120 angstroms. The coating consists, on a mixed metal oxide weight basis, of about 60 to 70% cobalt, 12 to 18% chromium, and 16 to 24% iron. A protective layer is placed over the coating.
