Abstract
A shaped glass article is provided that is ultrathin, has two surfaces and one or more edges joining the two surfaces, and a thickness between the two surfaces. The shaped ultrathin glass article has at least one curved area with a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied. A method for producing a shaped glass article is also provided that includes providing an ultrathin glass with two surfaces and one or more edges joining the two surfaces, having a thickness between the two surfaces and shaping the ultrathin glass to a shaped ultrathin glass article by forming at least one curved area having a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied to the shaped ultrathin glass article.
