I think this is the first time I've posted anything here though I have
lurked for several months.

It was interesting to see the reference to Water Glass here.  We supply
a chimney sealant which uses water glass in one of the coatings.  When
we were first supplied this from our Swedish parent company I looked in
the reference library (Glasgow's Mitchell Library is the UK's biggest
reference library!).  I couldn't find a single reference to this
material.
