Abstract
A system and process for forming a curved glass laminate article is provided. The process and system utilizes co-sagging of a stack of glass sheets of different thicknesses and different glass materials. During co-sagging the thicker glass layer is placed on top of the thinner glass layer. In this process, shape mismatch is avoided by selecting/controlling the glass materials of the sheets of glass such that the viscosity of the lower, thinner sheet during co-sagging is greater than the viscosity of the thicker glass sheet.
