A system and process for forming a curved glass laminate article is provided. The process and system utilizes a separation material, such as solid lubricating material and/or a spray applied separation material that Applicant has determined reduces bending dot formation during co-sagging shaping of glass sheets. The bending dot reduction provided by the separation materials discussed herein is particularly seen when the pair of glass sheets have significantly different thicknesses and/or viscosities from each other.

Process for forming curved glass laminate article formed using separation material

A cover element for a foldable electronic device that includes a foldable glass element, first and second primary surfaces, and a compressive stress region extending from the first primary surface to a first depth that is defined by a stress &#x3c3;of at least about 100 MPa in compression at the first primary surface. The device also includes a polymeric layer disposed over the first primary surface. The glass element has a stress profile such that when the glass element is bent to a target bend radius of from 1 mm to 20 mm, to induce a bending stress &#x3c3;at the first primary surface in tension, &#x3c3;+&#x3c3;&#x3c;400 MPa (in tension). Further, the cover element can withstand a pen drop height of at least 1.5 times that of a control pen drop height of the cover element without the layer according to a Drop Test 1.
