| Abstract: | A new technique combining a thermal-image furnace and a twin roller is described for quenching the melt to form glass. The technique was applied to the simple system Li2O-SiO2, since its fundamental parameters in the estimation of critical cooling rate are available. Glass flakes were obtained in the composition Li4SiO4, for which a very large critical cooling rate (∼109 K·s−1) was needed for glass formation. |
