sodium silicate, sodium metasilicate, water glass, liquid glass, Na2SiO35H2O, or, more correctly, Na2SiO2(OH)2·4H2O


concentrations of sodium silicate to water for various applications

Na2SiO3


sodium silicate pentahydrate, Na2SiO3·5H2O, is the common commercial variant most often seen. Note that the dried prills without packing are nearly the same density as water, so it's a good rough approximation to measure by volume.
