stock. Turned out that paper was having problems due to
recycled contect and strange, inconsistent sizing. I'll try again
and let you know.
I have also found that spraying a little deionized (or distilled)
water over the surface, before skimming seems to "clarify" the
bath, though not completely. I did manage to catch the problem
in time so it's not so bad- and can be "hidden" by doing shell
spot patterns, so the white areas appear as veins.
I use aluminum sulfate, which is an industrial grade that I get in
25 lb buckets form McMaster -Carr. It is not as pure as some
grades, so I started making up solution and letting it settle for
some time, sediment collects at the bottom, clarifying the
solution before use. I have been using 2 tbsp per quart of water.
So it's the same as the 1 tbsp to 2 cups water. the thing is that if
my "double strength " solution is causing so much trouble, then
maybe it isn't just the alum. So I look to other sources...
I have noticed a big difference in something so basic- the
newspaper that I use for skimming. My local newspaper
changed format a little while age. They went from using a larger
sheet size, to a smaller sheet size to save money. Apparently
many newspapers all over the country are doing this. Well, whn
they changed, the new newspaper stock was TERRIBLE. It falls
apart instantly. I need to use 2 sheets at a time just to be able to
hold onto the paper (I should mention I'm working in a BIG [28" x
95"] tray and skim with whole sheets of newspaper, not little
strips as some do in smaller trays).
I happen to have some "virgin" newsprint that I got from a paper
distributor for wrapping, and using for "gluing out" in
bookbinding. Now that's a nice sheet of newsprint! Seems to
have more pulp, better pulp? better wet strength at least.
Perhaps it has more "craft" content? I wonder if it may "absorb
more" than my newspapers. Perhaps the newspapers are also
adding pollution (since it disintegrates), rather than truly
skimming. This is true both when the paper is "aged" for
months, or fresh from the press. I usually let them "age" as they
seem drier, and less likley to get black ink all over everything.
Has anyone else noticed this problem with the newsprint? A
paper anyone recommends? Printed on better stock than the
South Carolina State Newpaper.... Maybe I should get the New
York Times weekend? Do the tabloids- New York Post or the
Boston Herald, even the National Enquirer have worthwhile
On the other hand, there is another issue that I can think of too.
many companies have converted to using "earth friendly" printing
procedures. This includes using soy based inks, and using
surfactant waterbased clean-up products that are designed for
these "softer" inks (the "old way" was to use solvents). I know
that for some (black and white) potions of the paper, they are
using this, but still use the "toxic stuff" for the color printing. Am I
putting soybean oil in my tray?!? I tried to getthe end of the roll
from the printshop, and used that, but it still fell apart in the bath.
I never thought I might have to BUY my newsprint for skimming...
c'est la vie...
