[Nhcoll-l] Fwd: Explore CCI's New Online Light Damage Calculator

[Robert Waller]

I agree with Helen though, in fairness to CCI, this is an early release
which includes only a small fraction of the colorants they hope to be able
to include over time.  As Helen says, the Blue Wool standards will be most
important to add.

Just as important, the old physical light damage slide rule is much better
for facilitating an intuitive grasp of varying the effects of colorant
sensitivity, light intensity and exposure duration.  In working within a
collection holding institution that is what we need most.  Hopefully, the
online version will be redesigned to recapture that most valuable aspect of
the slide rule.  In the meantime I don’t think anyone wants to retire their
physical slide rule yet - I think it remains one of the best tools CCI, and
even the whole conservation field, has ever produced.  That, in itself,
makes the physical slide rule a very tough act to follow up on!

Calculator

I was a little disappointed in this online version because it doesn't relate
to the blue wool fade card, which was the most useful part of the previous
calculator. Many small museums won't have a clue about the specific
colorants. And some of the listed colorants are extremely stable - which we
already know. If they had used the 8 dyes used for the blue wool fade card,
and then the other colorants were provided with notes as to how they relate
to the 8 dyes, THAT would have been so much more useful to us. I am holding
on to my physical light fade calculator. Seeing this online version makes it
more precious to me.
Best,
Helen
