Hi Rob...Hope this helps.
First of all, all teachers will tell you to toss it, the next will be =
better and so will you.
And remember, "It's only clay". My mantra when things go south.
That being said, it is really nice to have a few tricks in your bag.
The miracle of P'slip. Check out paper clay on Jerry Bennett's website
at www.jerrybennett.net . Great detailed info.
I use a low temp whiteware and have a compatible casting slip which I=20
make that contains sodium silicate, bentonite, and soda ash. I soak
the cellulose fibre in water, keep a jar going so it's nice and old.
I use about one part fibre to two parts slip. I compress the crack
and fill with slip that I let get dryer and thicker. Use a wet finger =
to=20
smooth, sponge wipes away clay leaving lumpy fibres. You won't believe =
this
but it works on greenware and bisque. I have filled a crack in bisque =
and=20
glazed over it then fired.
Unbelievable!
I handbuild combining slipcast, thrown, and slab. One current piece I =
have
been working on since January so I am not likely to toss it over a small =
crack.

I totally agree with Donna on this. While it may be a good idea to just
start over, I know how you feel about not wanting to destroy your pieces.
Paperclay is definitely the way to go. I have been working with the
temperamental B-mix. I happened to have two mugs which I decided not to
bisque fire. Instead, I put them in a plastic bag and pulverized them with
my rubber mallet. Gave me exactly two cups of dry clay. I then tightly
packed a cup with shredded toilet paper. Put them together, poured Lana's
Magic Water over it, just till it was covered. Left it for 24 hours. Mixed
it in a blender. Left it sitting out so that some moisture could evaporate.
Pretty soon I could wedge it. Oh, also added a tablespoon of bleach when I
was mixing it in the blender, that way it won't rot. This gave me a little
over a pound of paper clay. It is nice to have it on hand to repair things
when needed. I plan on doing this for each clay I use. Fixing a crack is
quick and easy when you have the paperclay on hand.
Good luck. If you need anymore info, just email me.
