On cleaning the glass, if you want to use the original, beware that some
of this glass is very "soft" and easily fractures. I actually cleaned the
glass of a Lerebours dag - now many thousands of dollars worth of image!! -
but it had to be reused and remounted. The underside of the glass appeared
to have a mercury deposit but very careful rubbing with a moist cloth using
a bit of vim did the trick. But my heart was in my boots as I did it! It
had to be done as the image was completly obscured by the dirty glass.
