    A Material Safety Data Sheet for water glass (sodium silicate
    solution) is at www.jtbaker.com/msds/s4982.htm 

    Related information, including more synonyms than are in the MSDS,
    is at www.cdc.gov/niosh/rtecs/vv8d8678.html 

    Some people also use "water glass" for a compound of potassium
    silicate. - for example:
    www.iversonsoftware.com/reference/chemistry/w/Water%20Glass.htm 

    Other people consider the potassium compound to be potash water
    glass - for example:
    http://www.plasterarc.net/essay/essay/CassarWY.html which has
    information on potassium and calcium compounds related to sodium
    silicate solution in a Glossary of Materials used in 19th and 20th
    century Plaster Architecture.
