Hi Marilyn,

    "Water Glass" is an old-fashioned name for sodium silicate.  Another
    common name for this chemical is "silica gel".  In the past it was
    often used as a concrete sealer, and as an ingredient in
    pharmaceutical products. 

    The most common use for sodium silicate is as a dessicant.  (You're
    probably familiar with it in the form of little "don't eat" packets
    and cylinders, which absorb the excess moisture in pill bottles.  Ask
    your local pharmacist to save them for you.  Pharmacists throw them
    away by the dozen.) 

    -Pete-
