The waste soda lime glass was converted to glass-ceramic by adding certain amounts of
alumina, lithium oxide and titanium oxide. The effect of quenching in air on the microstructure and
the mechanical properties were investigated. SEM observations clearly revealed that the presence of
homogeneously dispersed tiny single crystals with average size of 4ىm for quenching sample which
increased with holding time at the nucleation temperature of 650°C to reach a maximum size of
10ىm. The results of Vickers hardness tests indicate that the hardness value of the as quench soda
lime based glass-ceramic is 724 kg/mm2. This value starts to decrease with increasing holding time
at nucleation temperature to reach 687 kg/mm2 after 96 h for the crystals growth
