a technique that is from lou to rhudy to me....
(always give source on clayart)
take very hot water and add as much soda ash
as you can get into the water....keep it hot.
i use an old hot tray thing. keeps things warm like
a cup of coffee. electric.
apply with brush to a any shino glaze.
(or any glaze...try it.)
soda ash works as a flux, and is the first thing
to melt at about cone 012. hard reduction early in the
firing should give you very black shino where you have
painted on the soda ash (hot)
see last december, ceramics monthly...an article black shino...by me.
some history of shino
some malcolm davis stuff
some of mine,
and tom buck vetted about 40 shino recipes
and came to the conclusion that they are really
two glazes....with some variation for iron.
but, please read tom's work. it is much more
accurate than my ramblings.
even though it is my work...i will not publish it
on clayart. read the article.

I have been using soda ash on a limited bases. I've had the best results
when using 1/4 cup soda ash (2 ounces/60cc) to 3/4 cup hot water just as mel
said, actually boiling water mix well and apply. When fired to cone 10
reduction it produces a very warm inviting toasted orange, under painting
works well. The best is to leave it on the shelf for several weeks. I fired
2 vessels that were 'glazed" the day before and they did not have near the
color development that those that sat on the shelf had obtained. Did
increase the amount of soda as to half and half and fired after several
weeks on the shelf and produced a very glossy glaze with some toasted orange
areas but much like some shinos. I plan to try this again. Like the results.
