Synthetic Shimaoka Nami Jiro cone 10.

[Lee]

Anybody doing glaze testing?

Synthetic Shimaoka Nami Jiro cone 9/10.

EPK 49
Whiting 14
Dolomite 8
Silica 7.4
Custer 7.4
custer 24
Mag Carb .07
Bone ash 2.3
R. I Ox.  .08

        I will do a line blend adding 5 and 10% Kaolin.   I may test
tile 6 instead of EPK too.  When John Anthony tested for me, it beaded
and I would like it more smooth for glaze trailing over it.    If
anybody tries, please share your tests.

Lee,

Is there a misprint in this recipe? Custer is listed twice.

Thanks Paul!   Corrected recipe above!

Lee, do the original non-synthetic versions of Nami Jiro use wood ash or what? Just curious. You have some older photos up that look great. I know nothing about this glaze (type).

It looks interesting, I'll try it soon.
Thanks!

Yes.  I used:

3 parts washed wood ash
2 parts  Gariome Clay
1 part Amakusa Stone (porcelain stone.)

These were mixed by wet ladle measure (each material made into a slip/slurry, water skimmed off the top and then ladled out.)

Thanks Lee!
Interesting and easy way to mix an ash glaze, too -- I'll have to try it.

Lee,

Since I'm bored out of my skull why recuperating from surgery, I thought I'd run your original Nami Jiro through my Insight software and I came up with this version.

Nami Jiro Cone 9-10

talc                      0.95
Dolomite             19.21
G-200 Feldspar    43.92
Whiting               22.82
Bandy Black         6.10
bone ash               5.06
manganese carb    1.95


I chose the ingredients which would closely match the original. All the RO column ingredients and alumina match the original. The only exception is the K and N total is same but the K is not as high and the n is a bit lower. If I chose a higher K, it would have made the silica even higher. The silica is just a bit higher which actually helps the explain a bit. Both the original and this one are below the minimum suggested silica for a cone 10 glaze.

If someone wants to try this, they might want to try a Custer version too. It will have more siica and will affect the RO column as well. I chose Bandy Black because it supplies the trace of manganese that is in the original. I also use Pine Ash, as the ash, since I thought that may be the most likely ash that was used, since many or all of the wood kilns I visited in Japan used red pine. Also, the G-200 was based on the original G-200 and not the current one.

I'm only doing earthenware these days, so I won't be testing this; but if anyone does, I'd appreciate some feedback.

Warm regards,
June Perry

OOPS, that should have "while"recuperating. Also, other error - should have
read that the K is not as high as original, but the N is higher, making the total Kna the same as the original.

It's a ball clay. I chose it because it contains a trace of manganese which is in the original recipe.

Hi Lee, and Bill,

I think it's a GREAT idea to try to bring this list back to life. I would like to make some reconnections to the wood fire community. They are a kind of quiet bunch I think, and not very communicative by nature, but here goes an attempt.

What are you folks doing? Any wood firings going on? If not, have you got any plans for wood firing in the future? I you are going to build a kiln, what kind?

What's going on here is that we are getting ready for the 28th firing of the wood kiln this fall, October 27th through 30th. We have done a firing every fall and spring, relentlessly, since spring 2000. I think we are starting to get to know a little about how to fire the kiln, but it's a long learning process. As they say, the joy is in the journey. It's been a wonderful learning experience for me, and a fine bunch of people have gathered here around the kiln for firings. A few of the guys are coming out Thursday for a few hours of splitting and stacking, and kiln cleaning. Then the wood pile will be ready and big enough to satisfy me. I think we use about six cords of pine for a firing.

I've been making a lot of domestic ware, casseroles, bowls and mugs for this firing. That is what seems to regularly sell. What are you making these days?

I always enjoy the little magazine for wood firers, The Log Book, that comes out four times a year.

I hope you all are having a good year.

Craig, I left you a voice mail.   Call me about Korean Chusok/Harvest Festival.   Gonna be fun!

[James Cody Kroll]

I'm glad to see life in the list. I've never really responded before just read. I recently had a successful 5 day anagama firing in Corning, NY with Fred Herbst. I'm sharing a small train kiln with one other potter at Salem Art Works end of the month for a 3-4 day firing.

I make predominantly Tea Ware and Ikebana ware. I formally study the Urasenke School of Chanoyu and the Hijiri-Ikenobo school of Ikebana as well as 20 years in Aikido.

I'm currently experimenting with shino variations using the Freer sample as my guide, substituting wood ash for limestone and synthetic rice straw ash for silica. I'm also always experimenting with nezumi shino and chosen karatsu glazes. I live in the rust belt so I fire in any anagama I can find may-nov & gas fire nov-may. I'm looking for land this year or next to build a Sasukene kiln of Masakazu Kusakabe's design in the Rochester, NY area and maybe one on Oahu, HI with Cory Lum and Kusakabe Sensei in 2014. That what is going on here.

Hi James,

                If you can get your hand on a copy of the Studio Potter article by Jim Robinson  SP Volume 21 Number 1 by Jim Robinson entitled, "Revival Fires: Another Face for Shino,"     I've been experimenting with the Mino Shino which uses no clay, instead calcined Alumina.    Also, John Britt has many of the recipes from that article in his high fire glazes book.

It can be back order here:

Here are some of my Mino experiments.
