Dorothy Feibleman's History and Expression
(this talks about exposure in Japan not her laminated translucent porcelain history between 1969~1993)

Dorothy Feibleman held a workshop in 2007 at the Sakazuki Museum in Tajimi, Gifu.

The Inax design prize gave her translucent colored laminated porcelain expression a lot of exposure in Japan in 1993. After 1993 she was awarded many opportunities. She exhibited her expression at the Green Gallery in Tokyo at the time of her Japan Foundation Fellowship and another residency at Shigaraki. After being awarded a gold at Mino, she exhibited her translucent laminated expression at Ichinokura Sakazuki Museum in 2003 and 2006 & gave slide lectures. She also exhibited at Yufuku Gallery in Tokyo. After which, she held a workshop in 2007 at Ichinokura where she showed her original expression GEOMETRIC 1,2,3,4,5 slides shows below marked DEMO showing the dyed green and pink clay that is actually white. She demonstrated some of her other original translucent laminated expression.

The WHITE WHITE SAKAZUKI pictured above the demo photos, won a gold prize at Mino in 2002.

In 1997 and 1999, she was a guest artist at the Shigaraki Ceramic Cultural Park, Shigaraki, Shiga Prefecture, where she produced works, conducted workshops and gave lectures. In 1998 she gave a lecture at the Shigaraki Ceramics Technology Laboratory. "Here is an introduction to how Dorothy makes her laminated porcelain that she has been making for 40 years". (now 50 years)

Here is a very short slide show of how the type of piece above was made

The 5 slide videos below were made in Australia in 2004 for a class at Canberra photographed by Greg Daly.

Dorothy was using white porcelains in these slides.The pink and green colors burn out. The pieces were white like the ones above in this post. It is standard procedure in porcelain factories for material and process identification to put dye in porcelains used for different processes. They may look like the same porcelain and be the same porcelain sometimes except for the plasticizer used for flowers or jigger jolly or casting. Dorothy has (since 1995) used dye to identify her different whites she is laminating. This allows her to see what patterns she is making with white clay and to identify the translucency or color of different whites or opacity in each structural image she is making. Understanding this is important for her final expression after firing. Placement of white colors, textures and structural movement is all part of her expression.

The piece above (1999) made from several white porcelains. It is a similar construction imaging to the below demos. This piece was partially made in the UK and Japan in 1998-9 and finished at the Seto Ceramic and Glass Studio on the residency in 2000. There was a second one made from the same images but it was not perfect. It "was lost" by ...... there was a police report in Seto.
It is still "lost" probably in someone's private collection of endangered species items.

These two above photos are from a powerpoint presentation given in Hungary & in Japan.

Translucent porcelain "kneading" was produced using porcelain clay mixed with pigments or different white porcelain clays. Dorothy Feibleman was the first potter to develop her particular expression of structural translucent kneaded porcelain, and has been using structural translucent porcelain soil for 37 years. (now 50 years). At that time (1969), there was no translucent expression of kneading like Dorothy's in Japan, even with a long history. Not sure where this was quoted from at the time it was put in this blog but it is off by about +3 years.

In 1993 Dorothy Feibleman introduced the first structurally translucent colored kneaded porcelain clay to Japan. Before 1995, she used porcelain clay with textures and colored surfaces, but since working in Hungary in 1995, her repertoire increased to using white gradations with different translucencies, and textures.
This is a slightly better translation than given on google translate.

The Hungarian porcelain clay she used, contained Czech kaolin, she laminated it with her translucent white porcelain clay to make canes with a pattern like Plique a Jour or stained glass. The stronger dense white porcelain in the structure with the less translucent porcelain allows the more translucent porcelain to melt inside the stronger structure. The three finishes (1) 凸凹 unevenness, (2) 凹凸 unevenness, and (3) 平面 flat surface are determined by the firing temperature and firing time and her materials used. Basically, these three types of surface but actually structural unevenness come during all drying and firing and choice of materials in the clays.
What is not clear in the translation is that there are two texture types and the clays melt at different temperatures and move when they mature or are still porous.

1.凸凹 ガラス状の丸い構造(液体を透過しない)
1. Uneven/textured Glass-like rounded structure (is vitreous and does not leak)

2. 凹凸
2. Uneven/texture



In this example, the white matte is not mature. In addition, the recessed parts of the image are made of vitrified white porcelain clay. This uneven structure creates a shadow giving it a soft, velvet-like impression.

However, this chalk like raised part is like a low fired bisque unglazed piece, it is not suitable for use with food. Also, since it is not waterproof and porous, it absorbs water and becomes weaker, stains when exposed to oil, tea, wine, soy sauce, dirty finger prints, etc. It is very weak so it is not usually good for large work. 

*** Internationally, silicone waterproofing agents are not suitable for tableware due to food hygiene laws.

3.a. 平面
3.a. Smooth

If the porcelains used are chemically suited to each other they will vitrify within the same firing range.

Made in the UK in 1995 and 1997 and first shown publicly in Japan at the Seto Ceramic and Glass Center when she was a resident 1999~2000.

3.b. 波状の面
3.b. Wavy surface


If two types of porcelain are used, However, the shrinkage/vitrification point is within the same range of both porcelain clay but is not always the same. The result is a very interesting effect, like a small wave on the surface of the water. 


Dorothy Feibleman was the first ceramist to make available to the public, seven intermixable colors of translucent porcelain clay. It was sold by Podmores in Europe (later Potterycrafts) from 1984 until the company became part of Limoges.

In 1997, the late 松井 康成 MATSUI KOUSEI saw her translucent white and white textured vessels she produced at Shigaraki Ceramic Cultural Park. Like the small cup pictured on the left below. He said to the translators, "I want her clay" and Dorothy told him anyone could purchase it from Potterycrafts (the D.F. colored porcelain sold since the early 1980s). He purchased one ton of Dorothy's dry translucent porcelain clay from Potterycrafts U.K.

This white/white translucent piece was displayed in the Art Section 1998 at International Ceramic Festival Mino. It was soon purchased for the permanent collection at the Metropolitan Museum of Art in New York City.

This page was mainly about white/white work and was put on in 2010 in English.
Below is a piece that was in the same Mino '98 as the work that the Metropolitan Museum acquired.
It was made from translucent porcelain but was not photographed with light. It looks totally different with light shining through it.

In 1998 Mino Competition, Dorothy was awarded a silver in the design section for this piece of her colored work.
會田 雄亮 Yusuke Aida was the head judge in the design section that year.

In 1986, Dorothy Feibleman's laminated porcelain work was exhibited for the first time at Mino International Ceramic Festival in Gifu Prefecture. She won the Inax design prize in Japan in 1993, and since 1997, she has been making work in Japan regularly. After her production activity at the INAX Experimental Studio in 2000, she established an independent workshop in Tokoname City, Aichi Prefecture.

DOROTHY X NIKKO - Dorothy's nerikomi expression in bone china - online catalogue

Dorothy's nerikomi expression in bone china produced in Japan by Nikko Ceramic Company
Catalogue online today.
Three new lines by Dorothy. 

The catalogue is also coming soon in English.  
There are three new ranges.

I made the pastry (in the photo with the tea) on my new bone china tableware. I have made it since about age 10. Many people who taste it think it is from their country. I used to take it to Lucie Rie when I would visit her. It makes everyone happy. Here, I have put my general version, that I sent to a friend, one of the times I was a guest artist at Togei no Mori, in Shigaraki. When I was at university, I would put it in the freezer and secretly bake it in the test kiln (do not do this it is bad workshop practice) when the teachers were in meetings. They would come back and comment the department smelled wonderful. But,it would all be gone by the time they finished their meetings. I came back after Christmas break one year and Caroline had eaten it all and the freezer was empty. She couldn't stop eating it over the vacation. It even made my very dry teacher Franz Wildenhain smile. He left a meeting for it - he had a good nose.  Making it is similar to making my ceramic work. It is structural. I do serve my edible work  on my work often.  I always make it when I give workshops. So, we will make it at Meridiana for the students in Tuscany who attend my workshop. Since then, I must admit, that as an Inax Design Prize winner, in 1993, in Japan, I did bake a noteworthy chocolate cake (a recipe from Lucie Rie's family that she gave me) in a ceramic dry box in our workshop (not in the company). It took 4 hours but it worked perfectly. (I am not recommending dry boxes or kilns for preparing food in . But,I have a horrible suspicion, all potters do this at some time in their lives with the full knowledge it is idiotic. At the time seems convenient but they know it is really a bad idea). I have worked in companies (in the 20th century - I did not say 21st century) where at 2a.m. I smelled steak and followed the smell and there it was, on the kiln shelf at the end of the tunnel kiln, a thick sirloin steak and onions and baked potato in foil, on aluminum foil, next to a cooling down product.

The recipe is below:
