The use of industrial waste as additive in some production processes has been studied in recent years as an alternative to final waste disposal to develop value-added vitreous materials [1]. In particular, silicate residues such as coal fly ash, iron metallurgy slag and glass cullet are attractive for development of a broad range of glass-ceramic materials for technological applications in accordance with processes that seek energy optimization and the minimization of the environmental impact caused by industrial processes. At the same time, the goal of such approach is to obtain new (glass-ceramic) materials with improved mechanical and functional properties [1, 2]. In this research a new family of glass-ceramics utilizing waste materials from Colombian sources is being investigated and characterized. The main goal is to take advantage of the physicochemical and mechanical characteristics of particular waste combinations that can yield glass-ceramics with specialized properties providing an important link in the productive chain of Colombia for potential specialized technical applications.
