Oh goody, Jeremy. I thought maybe my
ultramarine had gone bad but then when I read that SVK said so, too, it was very
interesting. I have not smelled that with other pigments.

Yes! I thought I was just crazy, but glad to know it's not just
me.

Anyone
using ultramarine blue in gum printing notice this, that a sulfur
smell
is given off when mixing it in the coating solution? I did, thought
I
was being overly sensitive, but noticed that Sarah Van Keuren and
Rudi
Dietrich said the same. This doesn't mean it doesn't work--it
works fine in
gum, but it's just stinky...If ultramarine is sodium
aluminum sulfosilicate,
is it possible, chemists on the list, that
the acidity of the gum would be
responsible for releasing this smell? I
do have a hyper sensitive nose, I
have been told.

PS I am
working on the "certain pigments don't work" section...that
is
fascinating.
