Hi Jan, congratulations on your discovery of wonderful paper-clay.
We learned at NCECA this year it is fast becoming as popular
in the states as it is in the rest of the world, but we do have
some distance to go to catch up.
I make self framed tiles from paper-clay, I just fired the largest I've
made yet, 21 by 9 inches. They would not lie flat on the shelf so I fired
them on end and leaning against the kiln wall at the top edge. They
came out perfect.
I had a bad experience awhile back with firing them flat on the shelf where
4 out of 5
came out of the bisque with a crack from the edge towards center. I believe
this to have been a dunting crack during cooling. I now fire all my tiles
on end.
What size pieces are you making? How thick?
Here is a tip if you mix your own paper-clay, to keep the bacteria growth
down (read
smelly clay) I add 1 teasp of copper carb to my clay/paper mix while I am
mixing it up.
This is for a 5 gallon bucket full.
It isn't enough to change the fired color and so far it works great for me.
Hope some of this is a help,
Angela Davis
In lovely, green, and wet at last, Homosassa.

Hi I am
a
2nd year BA ceramic student
I have been experimenting with both small
and
large panels, I have used materials dipped into slip, to form a
panel,
which was fragile and crumbly, so I laid the materials dipped into
slip
onto a grogged clay, this bowed and cracked. I then reclaimed some
stone ware and laid the materials onto this, this too bowed and
cracked. I then made paper clay (using paper pulp,) very thin, with
materials dipped in the same clay, some of these cracked, not all the
way through, but they did not bow. The question I put to you is, do
i
fire these flat or would I be better standing them on thier side? As
you make paper clay ceramics, I wondered if you could through some
light on this for me

Jan,
the answer is simply this.........
after the paper burns away you are left with the clay that you started with...
it will bend and warp or stay flat and behave according to its nature.........
'inconvenient but for large slabs to be sure better fire clay on very
flat shelves,especially if you are firing to a high temperature
the paper's influence only works at the forming stage
