    Abstract: A glass article having a first glass layer, a second glass layer disposed adjacent to the first glass layer, and an interface slidably coupling the first glass layer to the second glass layer. The interface has a thickness of from 2 nm to 500 nm. The glass article is characterized by: (a) an absence of failure when the article is held at a parallel plate separation distance of 10 mm for 60 minutes at 25° C. and 50% relative humidity; (b) a puncture resistance of greater than about 6 kgf when the second glass layer is supported by (i) a 50 μm thick pressure-sensitive adhesive having an elastic modulus of less than 1 GPa and (ii) an approximately 100 μm thick polyethylene terephthalate layer having an elastic modulus of less than 10 GPa, and the first glass layer is loaded with a tungsten carbide ball having a 1 mm diameter.
