When working with strengthened glass, it is important to understand the terminology used to classify its characteristics. The terms MOR and DOL are used to describe a glass’s strength components. MOR, or Modulus of Rupture, refers to the surface compression, or the bend/fracture strength of the glass substrate. DOL, or the Depth of Layer, describes the how deep the ion-exchange process has permeated the surface of the glass substrate, thereby reducing flaws and increasing resistance.
