The theoretical and experimental foundations of the optical-radiation second harmonic generation (SHG) method are briefly reported. The optimum conditions for applying the SHG method both to an investigation of glasses and glass-ceramics at the early stages of the glass crystallization and to an analysis of the well-formed glass-ceramic structure are determined. The exceptionally high informative capabilities of the SHG method in studies of phase transformations of the {open_quotes}glass-acentric phase{close_quotes} type is demonstrated by the example of glass-forming systems containing the acentric phases [Li{sub 2}SiO{sub 3}, Li{sub 2}GeO{sub 3}, LiB{sub 3}O{sub 5}, Li{sub 2}B{sub 4}O{sub 7}, PbTiO{sub 3}, Pb{sub 5}Ge{sub 3}O{sub 11}, LnBXO{sub 5} (Ln=La, Ce, and Pr; X=Si and Ge), and others].
