I'm hoping someone with some experience with paperclay can shed some
light on a couple of questions I have after doing a little research here
and elsewhere on the web. Background: I'd like to try to make some
paperclay from a commercial moist clay I have.
Some of the "recipes" I've seen involve adding paper pulp to slip, in
some cases a casting slip (i.e. deflocculated) and in some cases a slip
made just by adding water to clay. My question is how the deflocculent
in the casting slip affects the properties of the paperclay, or if it
even makes a difference.
Some recipes suggest adding vinegar, partly I think as a preservative to
discourage mold from growing. But as per recent discussion here it also
acts as a deflocculent, although I've also read that it can interfere
with other deflocculents. So in short: to use vinegar or not and if so why?
Thanks for your insight!

Here's how I make paperclay from a commercial body.
Cut the clay into small chunks and dry them out on the top of a firing
Then take a 5 gallon bucket and fill it 1/2 way with water.
Shred the paper and add it to the water.
I like to use cotton linter that I get from Twinrocker, you can find
them on the web.
Stir the water with the paper added using a jiffy mixer.
Add the dried clay chunks to the paper mixture.
Let it slake overnight, remix it with the jiffy mixer.
Pour the clay onto a plaster slab and wait until it is the right
consistency to use.
***(I never make more paper clay than I need. The cotton linter grows
mold more slowly than scrap paper, but it will still grow mold. When
the clay smells, throw it out. I don't measure the amount of paper I
use. I just tear up pieces of the linter and mix it in the bucket until
it looks pulpy.) No vinegar is need when I make the paperclay.

I used to buy dry clay body from my clay store that I used for adding to
recycle clay. Can you get the same from your clay supplier? Might save
some work and you skip paying for the water you don't use.

If you want to make more paperclay than you will use right away, it is not a
problem at all if you let your paperclay slabs dry out. When dry, they do
not form mold and can be stored. Rewetting the dry slabs restores them to a
plastic state. I am not sure what the deflocullant does unless you want to
cast with the paperclay. I am planning to try it soon. I have not needed it
for routine handbuilding. Also I do not know about the vineger.
