RE: A PVA for printing "gum" from Mike Ware

My guesses would be (others, please correct me if I'm wrong):

1. It can be used with acrylic paints; a big plus for me since there's
only one brand of tube watercolors around here in Istanbul - that's
Schmincke, very good paints... but quite pricey when compared to
acrylics.

2. It can be used on synthetic surfaces like Yupo (or glass) because
it's more adhesive than gum; that's another big plus since synthetic
surfaces dry in a moment - imagine making a tricolor gum (sorry,
dichromated PVA) in just 2 hours!

About finding gum in Turkey... It's easy indeed (at least in Istanbul).
I buy raw gum lumps for instance. Didn't looked for ready made
lithographer's gum, but I'm sure I can also find that with a little
seach. Logically finding gum arabic in Turkey should be easier than
finding it in the States since we're much closer to Senegal, Sudan (and
other countries in between) ;)

Loris.

I have read, or tried to read the 5,380 posts on making gloy, or gloy
substitute, or a gloy-like substance that accrued in the 20 minutes I
was
offlist, but now I surmise from this citation that 14 baume gum is
(still)
the criterion. That's a substance I buy by the gallon -- now somewhat
up
in price, it seems, but last time my favorite was just $16. (About 8
British pounds, I gather.) Can someone explain why that's not good
enough?

(Any commercial printing supply source should have it -- even in Turkey,
perhaps. And it keeps forever -- the preservative is already in it. They
probably sell to anyone, too, even a reckless photographer.)
