Nucleation of the Li₂O.2SiO₂ phase from glass shows a distinct dependence on melting temperature while there is just a minute dependence on melting temperature for nucleation of the phase from melt. The largest amount of nuclei is formed in glass if this is heated closely above the melting temperature of the Li₂O.2SiO₂ phase. Monomers play a major part in the nucleation process in melts whereas polymerized units behave in this way in glass.
