Hi Alisa. Gee, I really like the idea you are describing. I've done some
work throwing colored clay, but never took it as far as you suggest.
My thought is to use only porcelain, or only stoneware, and use stains or
oxides to color the clay. That's what I did, and it worked fine. I wedged
chrome oxide and cobalt oxide right into the porcelain - I think I used 7
percent, or maybe 2 percent oxide, by weight.
One of the British potters is very good with colored clay, and explains his
process on his website. It might be Martin Howard, I can't recall. But I
used the percentage that he used, and made a blue porcelain, and a green
porcelain. Put them together in blocks with the white, and threw and faceted
them. I got some cracks on the bottoms of a couple pieces, but I was getting
cracks at the time, and I don't think these had to do with the colored clay.
The pieces were lovely. The different ways of putting them together -
blue/white/green, or white/blue/white/green, etc. - changed the swirls and
colors. It is mesmerizing to throw, or at least was for me (flashbacks). I
never got the glaze over these pieces as clear as I would like, though.
So at any rate, that's what I would try. Every time I've attempted to put
stoneware and porcelain together, it has not worked.
Best,

No, it wasn't me. I am still trying to find time to put up my website, but
it will be on www.webbscottage.co.uk soon :-)

Since we're cussing and discussing dunting, shivering,
crazing...how about cracking? I noticed yesterday
while giving a presentation a pot (everything I make I
call A pot)I made more than 10 years ago has developed
cracks along what I am assuming are the coil seams in
2 places.
It is a sculptural vessel made from a porcelain made
for hand building. I've used underglazes and a thin
coat of clear, mostly neph sys ^6 glaze. I collaged
paper maps over parts of the form. One of the cracks
starts under the collaged area or at its edge.
I use this pot often in presentations so I know the
cracks haven't been there very long. Any ideas what
happened?
