The present review is intended to revisit the advances and debates in the comprehension of the mechanisms of subcritical crack propagation in silicate glasses almost a century after its initial developments. Glass has inspired the initial insights of Griffith into the origin of brittleness and the ensuing development of modern fracture mechanics. Yet, through the decades the real nature of the fundamental mechanisms of crack propagation in glass has escaped a clear comprehension which could gather general agreement on subtle problems such as the role of plasticity, the role of the glass composition, the environmental condition at the crack tip and its relation to the complex mechanisms of corrosion and leaching. The different processes are analysed here with a special focus on their relevant space and time scales in order to question their domain of action and their contribution in both the kinetic laws and the energetic aspects.

• Effect of Humidity on Friction and Wear—A Critical Review (2018, background): “In the glass field, it is well known that the crack propagation velocity is greatly enhanced as humidity increases [181–183].”
• The Lower Bound for Glass Strength and Its Interpretation with Generalized Weibull Statistics for Structural Applications (2016, background): “It is widely accepted (Ciccotti 2009) that the brittle response of float glass is due to surface microcracks, which unboundedly propagate in Mode I once the positive crack opening stress reaches the critical value.”
• Atomistic aspects of fracture (2015, background): “remains a subject of considerable debate (Ciccotti 2009).”
