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.

Dry sodium silicate does not readily dissolve in water. Heating the water to nearly boiling will allow the sodium silicate to dissolve.
