The Rayleigh scattering of silicate glasses (M//2O-RO-SiO//2, M: Na and K, R: Mg, Ca, and Zn) was measured. Soda magnesium silicate (NMS) glasses exhibited the smallest scattering intensity. It is comparable with that of soda aluminosilicate (NAS) glass, one of the candidates for use in fabricating ultralow- loss fibers. The scattering intensity decreased with decreasing SiO//2 content, and NMS glasses with 60 mol% of SiO//2 are still stable against crystallization. It is concluded that NMS is a new candidate for ultralow-l
