    I remember having this in my chemistry set as a kid (1960-ish) -
    Sodium Silicate, it was a viscous clear liquid.  Only practical use,
    other than as a catalyst,  seems to be egg preservation.  If it's
    food-grade you would think it shouldn't be toxic when heated, but
    consult the MSDS if in doubt.  Apparantly it is still available:
