Abstract
The problem of glass relaxation under ambient conditions has intrigued scientists and the general public for centuries, most notably in the legend of flowing cathedral glass windows. Here we report quantitative measurement of glass relaxation at room temperature. We find that Corning® Gorilla® Glass shows measurable and reproducible relaxation at room temperature. Remarkably, this relaxation follows a stretched exponential decay rather than simple exponential relaxation, and the value of the stretching exponent () follows a theoretical prediction made by Phillips for homogeneous glasses.

The Deep Effect of Topology on Glass Relaxation
Published 24 June 2013
Measurement of ambient strain in a large glass plate shows structural relaxation far away from the glass transition region and reveals details of the underlying atomic network topology.
