SpectraFix fixative test: graphite on Derwent sketching paper |
A few
days ago when I blogged about my charcoal sketches, I mentioned that I was about to try a fixative that could alleviate
the transfer and smudging issues I’ve been having with both charcoal and
graphite. It’s called SpectraFix,
and I got it from DickBlick.com (it’s also available on Amazon). It’s available as both a concentrate and a ready-to-use
product. I was attracted to it because it is non-toxic (made of casein and
grain alcohol) and is applied with a non-aerosol pump spritzer.
This
is not a full product review, as I haven’t used it enough to evaluate fully,
but so far, I’m luke-warm about it. I purchased the concentrated form, which is
easy to dilute with “clear alcohol, such as vodka,” according to the label. (I
used gin, which we happen to have on hand.)
I
made the test swatches above with a soft 3B graphite pencil on Derwent
sketching paper, which I received at the symposium (110-pound weight). I smudged the top untreated swatch with more
pressure than a sketch in a sketchbook would probably experience, but I wanted
an extreme test.
I
spritzed the second swatch liberally and waited for it to dry completely; using the same pressure, I then
smudged the upper half. I spritzed again and waited for it to dry, but I apparently
didn’t wait long enough, because the damp paper wrinkled next to the lower
smudge. In either case, you can see that the fixed graphite still smudged a bit
(and I don’t see much difference between one application of fixative and two).
When held against another sheet of toothy Derwent sketch paper, I could see
some transfer, but not nearly as much as unfixed graphite. Since it’s made of alcohol
that simply evaporates, it leaves no visible or tactile residue.
A
greater concern with this lightweight Derwent paper is that it buckled from the
spritzing and stayed buckled even after drying (you can see it in the scan
above). After fixing these test swatches, I used SpectraFix on my Queen Anne cell tower sketch, which was
made on 100-pound Canson XL Bristol smooth. Despite its labeled weight, Bristol
feels much thicker than the Derwent sketch paper. It buckled slightly after
spritzing, but once it dried completely, most of the buckling flattened again
(which is similar to the response I get from spritzing 140-pound Canson XL watercolor paper).
Since
I tend to avoid toxic, aerosol fixatives that are more commonly used on artwork,
I don’t know if they would protect graphite better. Perhaps my expectations
were too high in thinking no smudging would occur after fixing. Still, it’s
safe and inoffensive to use, and it protects a sketch better than nothing. I’ll
keep giving it a try. If SpectraFix prevents transfer enough so that I can
still use the opposite sketchbook page, and if it keeps from spoiling a
finished sketch with inadvertent smudging, that’s probably good enough for me.
But if anyone knows of a non-toxic, non-aerosol fixative that works better than
this product, I’m all ears.
airbrush medium from Golden or Liquitex, but use an airbrush. it will mist finer than that spritzer does
