Candice Black In Japanese Materials
Test of Candice Black from John Britt's book.
TM Top Middle Hot Reduction / MM Middled Center Medium Reduc.
BM Bottom coolest oxidation
As you can see, the oxidation tile looks the best. I didn't have cobalt carbonate, so I substituted gosu (impure cobalt.)

The ash glaze I am working on is wood stove ash, gariome ball clay and amakusa stone (what they use to make porcelain in Arita.) It is my teacher's main glaze.

I put slip Gahon on bisque inside, for a test. In this case, it made the interior "dryer" and have more texture. I want to try this with single fired ash glaze.

The old workshop at Shimaoka's pottery. I never worked at it. It was torn down and the new workshop was finished a month or two before I arrived.

I went to a Yanagi and the Mingeikan show in Kasama. The first items in the show were works by William Blake and Walt Whitman and also work by Rodin. The Mingei movement began as an international movement.

William Blake and Walt Whitman had an important influence upon the Mingei movement.

Sculptures sent to the Shirakaba group by Rodin, after Yanagi sent him some Japanese woodblock prints.

Buncheong Ware 2nd half of the 16th Century.
The Museum of Oriental ceramics, Osaka
I first saw this pot at a show of Korean ceramics in Chicago, at the Art Insititute. I later visited it again in Osaka.

Edouard Bastarache's Lepidolite Glaze Tests
Edouard's Lepidolite test 1051
(French is Edouard's native language, so we will post French first. See below for English)
The recipies are posted at ClayCraft email list.
Introduction Française aux Glaçures Cendrées a la Lépidolite :
Ayant hérité de 10 livres de Lépidolite d'un ami-potier qui fermait son atelier, j'ai décidé d'expérimenter avec ce matériau contenant du lithium qui n'est plus disponible sur le marché.
J'ai déjà discuté des substitutions de ce matériau dans mon livre "Substitutions de Matériaux Céramiques Complexes".
De manière à éviter la production de cloques, j'ai utilisé des quantités médianes de Lépidolite, J'ai aussi utilisé de la Cendre de Bois Dur (Lavée 5 fois et tamisée à 60 mailles) et une fritte de boron pour obtenir une texture de surface que j'appelle "Scintillant".
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
English Introduction to Lepidolite Ash Glazes :
Having inherited a 10 pound sample of Lepidolite from a potter friend closing down
his shop, I decided to experiment with this lithium material unavailable anymore on
the market.
I have discussed the substitutions of this material in my book :
"Substitutions for Raw Ceramic Materials
In order to avoid blisters I used a medium amount of Lepidolite. I used Hardwood Ash
(Washed 5 times and 60-mesh sieved) and a boron frit to obtain a surface texture that
I call "Scintillating"
From Glenn C. Nelson’s Ceramics, a potter’s handbook, page 322 of the fifth edition, I have obtained the following chemical analysis of Lepidolite :
SIO2 = 55.00 %
AL2O3 = 25.00 %
FE2O3 = 00.08 %
K2O = 09.00 %
NA2O = 01.00 %
LI2O = 04.00 %
Ignition loss = 0.92 % + 5 % fluorine.
Fluorine is volatile and may cause blisters at high temperatures (Robin Hopper in The Ceramic Spectrum,1984, page 52).
Using the method described in Daniel Rhodes, revised edition of Clay and glazes for the potter at chapter 13 “Glaze calculation using materials containing more than one oxide” under the heading “Feldspar formula” I have defined the following formula for Lepidolite since it is a feldspathoid considered here in its fired or calcined state =
K2O .392 AL2O3 1.0 SIO2 3.743
NA2O .065
LI2O .543 Molecular weight = 384"

As you can see, this model is a later one, and sports and opening for a screw on lid. No doubt the old farmers still use their's and that is why the ones at the flea markets and junk shops are the ones without their lids.

This is glazed with Mashiko Kaki. Mashiko Kaki is the Japanese "Albany Slip."

These are inspired by Korean Sue and Japanese Yayoi ware. The middle pot (a vase) is inspired by a Yayoi vase my teacher has. The two covered bowls on the right are offering bowls for the Buddhist altar, the ones that I have seen are usually made of lacquer. I've been told that Samurai used to use tea bowls on pedestal something like these.
