Subject: Book damaged by cola spill
Advice is
sought on a volume which has been damaged by a spill of
Cola. The Cola
had been spilt over two pages of the volume close to
the spine towards
the top end of the leaves. Some of the liquid
appears to have seeped into
the top guttering of the volume and the
splash marks are a brownish
hue.
It is evident that the liquid has not fully penetrated the
surface
of the paper (this may be due to the fact that the paper appears
to
be of good quality with a high size content If only she'd
told us the
high five content ), although slight
cockling Thank God it's only slight is evident around
the main spill area.
The Iron Gall ink in the main area of staining
seems to have faded
considerably. This story goes from bad to
worse
Examination under the microscope revealed some loss
and abrasion of
the top layers of the paper fibres in the area of the
spill. Perhaps
this may have resulted from attempts to dry off the
spillage. It evidently didn't occur to Ms. Kelly that the
"reader" may have been furiously trying to erase the page (maybe s/he was
sanding it in preparation for a ne coat of paint?) when the Cola
spill occurred.
Examination of the faded areas showed that some
of the ink-bearing
fibres had been completely removed from the surface of
the paper. This changes everything. Now I'm upset,
too.
pH tests of non contaminated areas measured 7.5 on
average. The
non-contaminated areas measured 7 on average. All I
can say is "wow."
If anyone has dealt with a volume which
has sustained similar damage
in the past your thoughts and advice would
be welcome. My entire library had Guinness spilled on every
page of every volume. Do you think she may have run across that
problem?
