Re: Suggestions for sizing gum in an apartment
I'm one who tried it (and yes, I did try the right product) and
didn't like it. I used it at full concentration, since one person
who uses it successfully applies it at full strength, and it gave me
a hard, shiny surface that the gum didn't stick to well, and even
diluted by half it was still too plastic-y for my taste ; any less
didn't provide enough sizing. In a conversation here, (too hurried
to look it up in the archives) I think we agreed that it probably
depends a lot on the paper; Jim uses a more absorbent paper and the
stuff soaks in more, while I use a paper with a very crisp surface
(Arches bright white) and the stuff sits more on top. So I think
it's probably a matter of playing around with concentrations until
you get a combination that works with your paper. While I didn't
like it for my own work with my own materials, I would definitely
recommend it for people looking for a nontoxic size; I know it works
like a charm for several people, and I certainly wasn't intending to
discourage anyone from trying it, simply reporting my own experience
with it.

You can always try Gamblin PVA Size...not adhesive, but Gamblin PVA
SIZE.
Jim Larimer and Janet Matthews use it, as well as several others.
Not toxic, no smell, etc...different than gelatin.
Some here have tried it (or they actually tried the wrong product?)
and didn't like it, but it's worth a shot especially in confined
spaces or for those with health issues. One of the people I know of
who uses it and produces wonderful tricolors as well as gum-overs
has had a double lung transplant and will not jeopardize his health
with the nasties.

hi jeremy,
same problem here. i use chrome alum instead of the aldehydes. the
hardening process takes longer, but it's a powerful hardener too
and no obnoxious fumes. the solution has a slight purple colour,
but it's not noticeable, unless you're using a very thick layer.
i use about 0,3gr for 100m of 5% gelatin.

I'm back in an apartment, but this time with a dog and a wife,
and am curious on how others size in their very limited spaces. I
used to size on my apartment patio, but it has been overtaken by
my wife's apt garden and I am afraid of the ubiquitous potting
soil plus the Texas wind. I could size in the bathroom, but the
fan just blows the air back throughout the house and I'm worried
about fumes (of course safety, but also just smell), plus trying
to dry all of the sized paper could be a problem.
A while back Christina posted how she sizes and uses a multitude
of floor space in the process so I'm wondering about how those of
you with much less sprawling space tackle the issue.
