hi!
does anyone know about color shino? when i looked at clayart database, i
found couple of color shino recipes such as green shino and peach shino. i
haven't tested those glazes yet because i have heard that color shino is
good for soda firing and i'm unable to have soda firing. i'm not sure that
color shino works for "regular" reduction firing.....do u think that other
colors are available in shino such as blue and purple?
i have seen some color shino glazes in magazines. i know that malcom davis
has some color shino recipes. so, i tried his red shino, but somehow it
didn't turned right unfornunately. and i also tried to use some different
clay such as newman red, apache clay, and crocus martis instead of red art.
newman red and apache clay glazes....i got alomst same texture as "shino",
but not close to "red." i got more like bright orange with dark orange
flashing which i like. crocus martis...i got dark purplish brwon with cool
metalic surface, but this glaze doesn't look like shino! i wish i could
contact to malcom davis.....
the original shino in japan is thick grey. some potters in minnesota and
wisconsin are using different type of shino glazes. randy johnston has
opaque orange shino. will swanson has opaque red shino. i don't have
recipes of those glazes, but if anyone knows, please let me know.
anyway, i would like to know more about color shino glazes. please help me!

Check out the clayart archives. There have been a lot of discussions and
recipes posted for shinos, as well as firing techniques. Basically, to get
good red shinos, you need to reduce early (cone 012-010), on an iron bearing
body. You could probably use a low iron slip on a white body as well.
You might also want to play around with slips under a classic shino to get
various colors. A classic shino would be somewhere between 75-80% spar and
the remainder in clay. You might try adding 3-5% sea salt in some of the
tests. Try soda spars/Neph Sy/Potspars, etc. You can also try additions of
colorants to the base glaze. Experiment. It's fun and can be very rewarding.
Warm regards,
June

Hello,
It is not necessary to fire shinos in a soda firing.
Yes, the traditional shino glaze from Japan has been altered in the
west, to be something entirely different. The shinos over here with
high soda ash content melt very early and need early reduction, i.e.
cone 012-010, to get decent carbon trapping, if that is what you
want. It is a glaze that is extremely sensitive to kiln atmosphere.
Sometimes the same glaze will come out white, pink, orange, red,
black, grey, sometimes on one piece there is a huge variation of
colour, white on one side, orange with black dots on the other. (I
use porc.)
Advice that I took from Craig Martell was to replace half my epk with
200m alumina which I did. The glaze became "fatter", and sometimes
deeper in colour. I use Malcolm's shino recipe, without the redart,
and have replaced half the epk with 200m alumina.
Get your hands on a copy of the Studio Potter, dec.'92, Vol.21, No.1,
issue. The article by Jim Robinson is full of information. There are
lots of recipes in there to try.
If you want a "blue" shino, use a black slip beneath it. If you want
a redder shino, use a cone 10 clay body with lots of iron in it. It
will give you very deep red shinos. Even a buff stoneware will
increase the colour of red. Takes very little iron to make shino a
deeper shade of orange/red.
Sounds like you have been bitten by the shino bug.
Good luck, Liz
