inquiry for ron roy: ^6 shino

Ron;

At NCECA this year you spoke about seeing what looked like a "real" Shino
glaze fired at ^6 in one of the display rooms and were going to follow up
with that particular potter (name unknown) and do some investigating
yourself about how to develop a ^6 Shino. Any success on the ^6 Shino
front? Where would you begin to explore this issue, - and for that matter
what variation of "Shino" could be developed considering the
characteristics unique to ^6 firing? Thanks for your thoughts.

Roger

Roger,,,,,,,,,,,I think I get a fairly good shino type glaze with Nutmeg.
Just substitute Redart for the kaolin. I think this glaze could be adjusted
to give you what you are looking for. It gives a satiny almost matt cream
breaking reddish type glaze. Nice and smooth. You can see it on the vase
on my primitive web site on the vase.

Randy
The Sodumene you have listed in your nutmeg is in low fire spodumene?
Thanks, Joan

I think any "surprise" is only due to a misunderstanding about
traditional glazes, especially shinos. For the most part, before the
ntroduction of korean climbing kilns in the 17th century, most of the
single chamber wood kilns averaged about cone 1 in most of the firing
area. But they were fired for a week or two at these lower temps.
Also, they were not reduced like what we are used to in reduction in
modern gas kilns.

Here is a cone 6 Shino I have had good luck with in woodfire. In
recent correspondences (a paper letter, after sending my mentor back
home a new shino sample of mine), he mentioned to me that he gets
similar pinholing and crawling with his cone 5 shino by adding Gerstly
Borate.

Cone 6 Shino Translucent (can be mixed with cone 10 for middle temp 
areas)

G.B. 5
Soda Ash 4
Spodumene 22
Neph Sye 54
OM4 15
Bentonite 1.5

Good over iron wash.

Hi Roger,

I did follow that up and it turns out the sample I was shown was done in
reduction - at cone 6.

I have come to the conclusion that if you are going to use a "traditonal"
shino recipe you are going to have to fire it in reduction to get the look.
Pity.

On the other hand I do think it is possible to get the look in other ways
and I am sure there will be further developements in the future - all we
need are the one thousand monkeys in a pottery lab somewhere doing the line
blends.

I am fairly certain it will involve two glazes - or perhaps a glaze and a
body or a slip - and maybe some slow cooling - I'm also sure it will happen
sooner or later.

I have a couple of ^6 ox shino
look glaze recipes. They have actually tested nicely but I don't have
those records on hand. They do lack the metalic look you sometimes get
with the reduction firing but I recently saw a potters work using an albany
overspray that had that look.
