Taylor- I've just completed a large five+' high paperclay pc. Kept in ck.
with my bible: PAPER CLAY by Rosette Gault. A&C Black . London (University
of Pennsylvania Press). To answer your ? I believe you are toatally safe
to make the application you want to do. In this piece I've just completed,
I made numerous additions to bone dry surfaces. No problem. Be sure to
prewet the bone dry work first and score the surface prior to applying the
paperclay! You should have good success!

Howdy everybodies and persons,
I've got a specific paperclay question.
How effective is paper clay slip at attaching non-paper clay pieces
together at hard leather hard or bone dry? I've got some gnar gnar
made up but I don't want oozing attachments on all my pieces.
Somewhere in my reading I thought I read that paper clay can actually
stick two pieces of bone dry clay together without cracking. Am I just
making that up?
I can't fire entire loads of paper clay with my electric kiln set up
but I just might risk some paper clay attachments if it works for my
application.
How's the spanking going folks?

Taylor,
I use paper clay slip all the time, and I have never had success in
joining two bone dry pieces of greenware , or even bisque using the
paper clay, unless there was preparations first.
For the greenware, I put a little patch of high rag paper over the
attaching points of the pieces to be joined, then soak them in magic
water (visit the archives for the recipe). After some soaking, I remove
the rag, apply the paper clay slip to both areas and press. I then use a
tool to clean up the edges of the joined area.
For bisque, follow the same procedure - BUT - use ONLY calcined clay to
make your paper clay slip. Otherwise differential shrinking will occur
and the piece will crack - virtually guaranteed!
A final trick is to mix a bit of calcined clay with some glaze and use
that to fill cracks.When glazed over, then fired, it all becomes part of
the piece.
Regards.

This thread is fascinating. . . ! . . . I'm very curious though how
strong is the joint when you do this?? . . are we talking about hi-
firing the resulted join?

Taylor,
I have used paper clay slip to repair bisqued pieces. I did not use
calcined clay. What worked best for me, was to wet the area to be
attached and then applying slip quickly and stick the pieces
together. Immediately claen up excessive ooze.
For sticking grrenware together, I have used SPOOGE recipe from the
Clayart archives.
It is clay, karo syrup, paper pulp, water. I use vinegar and less water.

You should always re-bisque a paper clay repair job on bisque ware.
Otherwise, there are glazing problems. I think the resulting repair
is as strong or stronger in the end.( after high fire)
