Hi! I'm trying to find a suitable fixative to protect my drawings made with oil- and wax-based colour pencil on 300gsm Arches hot pressed watercolour paper. I only need to protect against accidental smudging and UV protection is not my concern (I only use ASTM 6901 grade pencils).
I've tried a Schmincke universal fixative so far (I live in Germany so that was a natural choice) and it gives good smudge protection and almost no colour change. However it lists "polyvinyl resin" as its main binder which is ambiguous, and Schmincke have officially declined to disclose any further details on the type of resin they use. From what the industry uses, I assume it must be polyvinyl acetate which is known to slowly disintegrate, releasing acetic acid. Assuming that fixative indeed uses polyvinyl acetate, would you consider it archival enough to be used with paper and colour pencils?
My second question is: what's the best recommended smudge protection fixative/varnish for oil/wax-based coloured pencil works on paper? I did a fair amount of googling but resources related to coloured pencils protection are virtually nonexistent (also no vendor in Europe, to my best knowledge, market any varnishes/fixatives as specifically suitable for coloured pencils).
Thank you very much for any assistance you'd be able to provide with this topic!
Answers and Comments
I have sent this to our colored pencil representative
I know we are waiting for an authoritative answer, but I did want to mention Sennelier D'Artigny Pastel Fixative. This product is "vinylic resin" in an alcohol carrier solvent, which should not soften or fuse with pencil layers.
I do not know this for sure in the case of the Sennelier
product but Poly vinyl acetate in an ethanol solution is a very typical alcohol
soluble vinyl. We sometimes use lower molecyular weight PVA resins in ethanol as a binder for conservation
inpainting paints. I am speaking about a
solution of PVA and not a dispersion. I can reach out to Sennelier to see if
they want to comment or identify the resin.
I hesitate to make any definitive statements about conservation
issues relating to paper (as I am trained as a paintings conservator) but did
want to mention that Elmer’s Glue and even Jade 403 Neutral PH PVA Adhesive (used
by many in libraries/etc) are PVA dispersion adhesives. Again, this is not
really a statement about the appropriateness of PVA on paper but only that it
clearly has a long history of use, at least as a dispersion. I have forwarded
this question to a few other moderators.
To answer the first part of the question;
we are not qualified to address the question about the archival
qualities of polyvinyl resin. That is a question best posed to a
conservator, especialy one who specializes in works on paper. Since the
Schmincke fixative was originally developed for use with pastels, it's
possible that someone in the pastel community may be able to help, but
we still think the best resource is a conservator.
The second part of the question;
typically turn to fixatives and varnishes made by Krylon, Prismacolor,
Winsor & Newton, Sennelier, Lascaux, and Schmincke. These are all
professional grade products that have been tested over time with good
results, mainly by pastelists, but also by colored pencil artists. A
newer entry into this market is the textured fixative and final fixative
marketed by Brush & Pencil, which has been availble for about 4 or 5
years and is marketed specifically for colored pencil. We strongly
recommend that artists ALWAYS try out any fixative product on test
strips of colored pencil before spraying the product on artwork. The
best practice is to create a test strip of each colored pencil to be
used in a drawing, on the same substrate to be used. Each strip should
be at least half an inch wide and 2 inches long. Cover half of each
strip and spray the uncovered half. Allow to dry and remove the cover.
Compare the covered half to the sprayed half to see whether any unwanted
changes in hue, value, or intensity have occurred.
Hopefully this will give the original poster direction toward finding solutions for their concerns.
