I am just getting into porcelain and I am looking for suggestions of books
to get me started. I am particularly interested in forming techniques,
firing schedules and glazes as they differ from stoneware.
I am especially looking for some celedon and chun type glazes for oxidation
firing and crackle glazes. I am trying to mimic some glaze effects that I
have on old asian pieces.

Hi Al,
I can't help you with celadon, chun glazes for oxidation firing. I fire porcelain in reduction at cone 10, and that is the only atmosphere I know of that will produce celadon and chun glazes from the addition of iron, wood ash and bone ash. There's no reason I can see that a crackle glaze couldn't be produced in oxidation, but even then, there is a character to a reduction fired clear or translucent glaze that crazes (crackles) that isn't present in the type of oxidation produced in an electric kiln.
You inspire me to include a section on forming techniques in the book I'm writing on porcelain. I can certainly help you with a firing schedule if you fire to cone 10 in reduction. ALL glazes have a certain clarity over a porcelain body that differs from the way the same glazes look over a stoneware body, because of the white background that porcelain clay provides, even dark and opaque glazes.

Not all stoneware glazes work well on porcelain. My standard ash
glaze shivers on porcelain.

Hello Al;
I handbuild porcelain pouring vessels. I didn't find
any books on porcelain handbuilding that was useful. I
used a UK porcelain [cone 8] with fine grog and it
worked well. I worked a bit faster with porcelain than
I would with stoneware clay. There was a bit more
'nursing' involved with porcelain. I dried the wares
very slowly. Just go ahead and build with it. You'll
find out what you can and cannot do with the clay soon
enough.
Any glaze you use on stoneware would be good on
porcelain. Of course they would look different. Mike
Bailey's Cone 6 Glazes could be a good starting point.
There are [faux] chun type glazes and crackle glazes
in there.
If you are trying to get 'snowflake' crakle, that has
to be done in reduction.
Regards
May
