Abstract
Hot stage transmission electron microscopy has allowed the nucleation sequence in a 30 mole % Li2O-70 mole % SiO2 glass to be monitored in situ. This result agrees with previous work, in that the sequence of phases observed is identical but small temperature changes give rise to pronounced morphology changes. Hot stage electron microscopy has been proven to be a very useful technique for observing glass crystallisation processes, but the results must be carefully interpreted because of possible surface effects.
