When crystal nucleation occurs in glasses, it is difficult to ascertain whether the crystallization has initiated homogeneously or by a heterogeneous mechanism. Here we suggest a method which might enable one to make this choice, and it is applied to the bulk crystal nucleation observed in Li2O · 2SiO2. It is concluded that crystal nucleation in the latter system most probably occurs homogeneously.
