Abstract
An oven view window comprising a glass substrate, and having disposed on a major surface thereof, a thermally activated, light-scattering coating which, when at a temperature below the activation temperature of the coating is translucent-to-opaque in appearance, but when at a temperature above the activation temperature of the coating is essentially transparent in appearance. Optionally, an infrared reflective coating and a color suppressing coating may also be deposited, in a variety of configurations, onto the oven view window carrying the thermally activated, light-scattering coating.
