Abstract:
A method includes contacting a second layer of a glass sheet with a forming surface to form a shaped glass article. The glass sheet includes a first layer adjacent to the second layer. The first layer includes a first glass composition. The second layer includes a second glass composition. An effective viscosity of the glass sheet during the contacting step is less than a viscosity of the second layer of the glass sheet during the contacting step. A shaped glass article includes a first layer including a first glass composition and a second layer including a second glass composition. A softening point of the first glass composition is less than a softening point of the second glass composition. An effective 108.2 P temperature of the glass article is at most about 900° C.
