Commercial glass strengthening and safety technologies: lessons learned and yet to be learned

This is the fourth in this series of “Lessons Learned and Yet to be Learned” on topics related to glass strength.^(1-3) In this paper we pick up the topic of stronger glass products from our earlier publication⁽²⁾ and expand to discussing commercial technologies. Included in this discussion are a brief historical perspective of the initial technologies and update to newer technologies with the aim to obtain faster production rates that focus on lightweight glass products and a sustainable future with respect to resource conservation, reduced energy consumption and reduced CO₂ emissions. Also included are glass products which focus on safety mostly and less on overall strength.
