re-firing shinos

A few weeks back there was a mention of re-firing shino glazes to bisque temperature to bring
out more of an iron red colour. I hadn't heard of that before so I gave it a try. It certainly does
make quite a difference and I've put a before and after image online:

This tea bowl was re-fired once to cone 09. I'll try to re-fire it a few more times to see if the effect
continues to develop.

Here is the recipe for the shino glaze used:

neph. sy. 44.1
ball clay 15.
NC4 feldspar 13.2
spodumene 8.8
soda ash 7.1
queenston shale* 4.8
EPK 4.4
petalite 2.6

*This is an iron bearing, clayey shale found in southern Ontario.

Lee,

I like that glaze "as is" as well. The low temp refiring is an interesting t=
echnique though, and
something I'll keep in mind as an option.

Steve,
I really like the subtleties(sp?) of the first firing. I love the
golden orange of the twice fired. The white looks more like frosting
though.

Hi Steve,

I must say I rather like the refire, like the crawl too.
As another example, I have posted two bowls I bought from Jiri Minarek of I
think, Penn State Shino fired in redux and then re-fired in electric oxidation,
a thing I'm meaning to try. Jiri leap in and correct me if I'm wrong please.

Thanx

Steve, thanks for the photos. But the question is, Which one do you
prefer? I like the colors on the unrefired pot best.
