Hi Judy
Just a thought: there are many additives available to alter acrylic
paints. One such additive is a medium that will allow the paint to remain
workable (wet) longer than normal. Perhaps you could test to see how
these additives work with velvet underglazes for silk screening? Or you
could try adding good ole glycerin to your velvet underglaze.
Good Luck

I'd like to be able to silkscreen underglazes,
Velvets, and stained slips onto medium-soft
leatherhard clay. While investigating photo-silkscreen
and Gocco printing, the Australians (who would seem to
be more advanced in ceramic Gocco printing than we
are) noted that commercial underglazes dry out too
quickly to be silkscreened. I tried a quick run with a
Velvet through a 200 mesh screen (they use that and 70
mash screens) and it worked though it might have
clogged the screen for a longer run. The "what you see
is what you get" palette of the Velvets really appeals
to me. Any ideas of what I could add without thinning
or lessening the color intensity? I'd rather not have
to start with dry underglazes but if I do, who sells
them? And I prefer the water-based approach for all
but decals which are oil-based. Which brings up a
final question: any recommendations for an oil-based
medium so that I could make decals out of higher
firing materials (slips, etc) than China paints? Many
thanks, Judy Schaefer

You might try to add glycerin to retard dryingt. Start with small amounts at
first ntil you find thed correct amount.
