A property-enhanced cover sheet, and methods for forming a property-enhanced cover sheet, for a portable electronic device are disclosed. A property-enhanced cover sheet is formed by thermoforming a glass sheet into a specified contour shape while modifying one or more properties of the glass. Other property-enhanced sheets can be formed by layering two or more glass sheets having different material properties, and then thermoforming the layered sheets into a required contour shape. Property enhancement for a cover sheet includes, hardness, scratch resistance, strength, elasticity, texture and the like.

A glass for chemical strengthening has a Young's modulus E of 70 GPa or more. The glass satisfies X.sub.1+X.sub.2+X.sub.3 being 1760 or less. Here, X.sub.1 is a numerical value equivalent to a value [unit: kPa/° C.] obtained by multiplying the Young's modulus E by an average coefficient α of thermal expansion at 50° C. to 350° C., X.sub.2 is a numeral value equivalent to a value of a temperature Tf [unit: ° C.] at which a viscosity of the glass reaches 100 MPa.Math.s, and X.sub.3 is a numerical value equivalent to a value of a difference [unit: 10.sup.5 Pa.Math.s] between the viscosity (100 MPa.Math.s) at the Tf and a viscosity η.sub.+10 at a temperature 10° C. higher than the Tf.
