A series of sintered glass-ceramic and glass-ceramics formed by bulk crystallization of Cathode Ray Tube (CRT) glass cullet mixed with calsiglass and calumite was investigated. Glass-ceramics materials prepared by the controlled crystallization of glass have a variety of established uses depending on their uniform reproducible fine-grain microstructure, absence of porosity and wide-ranging properties that can be tailored via composition and heat treatment. The laboratory results demonstrated that it is possible to produce a glazed tile, where the glaze deployed CRT glass cullet instead of commercial ceramic frits. Glass-ceramics were obtained at low temperature and short reaction times with the lead-free panel glass as one component.The crystallization experiments were carried out on the basis of differential thermal analysis (DTA), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The resulting glass-ceramic had sufficiently large compressive strength for practical use.
