Glass-ceramics were prepared from wastes generated from refining of silica sand and kaolin clay, called Kira. Several kinds of Kira were melted at 1300–1550 °C with additions of CaCO 3 and quenched in air or water to obtain glasses. The quenched glasses were ground to <48 mesh and used to prepare glass-ceramics.
