We discuss hidden damage of glass by the rolling process, which results in heterogeneous distribution of microcracks on the edge surface of glass element, which are the fracture source deteriorating glass element strength. It is shown that removal of this damage on the edges of glass elements increases the engineering strength of float glass significantly. Using the hidden damage approach, we provide strength determination for the weakest specimens that is statistically relevant and is based on a reliable engineering parameter.
