  • An old Porcelain Stone Mine

    It’s surprising to me how often archaeological discoveries seem to be made in Jingdezhen, but then I remember that wherever I walk in this place there are deep layers of shards beneath my feet. A friend of mine was given samples from a recently found porcelain stone mine dating from the Five Dynasties Period.  Apparently the find has not gone […]

  • Triaxial testing

    A lot of potters in China still seem to mix glazes the old-school way- one cup of this, two cups of that.  And strangely enough this technique seems to work pretty well for complex traditional materials.  Being a foreigner I tend to make things overly complicated.  I am also terrified of mixing up a great glaze […]

  • Sanbao Porcelain Stone and Saggar Kiln

    Nestled in the beautiful mountains near Jingdezhen is Sanbao, a traditional source of porcelain stone. Porcelain stone comes in many types characterized by the local geography. Sanbao stone is primarily used in making porcelain bodies, but it can also be used in glazes.

  • Ash Glazes

    All of the following ash glaze recipes and more can now be found on my new open-source ceramics recipes website, Glazy: https://glazy.org/search?base_type=460&type=1060 I’m not particularly an ash glaze aficionado, and I’m far from an expert.  But it’s surprisingly easy to make an interesting ash glaze, and it’s nice to have some “natural” glazes which give interesting surfaces on functional ware. The digitalfire […]

  • How I Make Glaze Test Tiles

    October 2020 Update I’ve simplified my test tiles. Now, the test tiles themselves are just simple slabs of clay. But I make test tile holders out of a strong clay. Flat, Square Test Tiles Flat test tiles cut from slabs are ideal. You can easily make them from any type of clay. No need to […]

  • Qinghua Stone

    Pictured above is a type of stone (叫珠子) mined in Zhejiang province and sold in Jingdezhen.  It is primarily used for making Chinese underglaze blue & white (qinghua).  These hard nuggets are quite expensive, while the softer stone surrounding these nuggets is about six times cheaper. In the magnified view you can see that this stone is […]

  • Porcelain Stone Glazes

    Jingdezhen Porcelain Stone There are a number of types of porcelain stone mined throughout Jingdezhen and the surrounding countryside.  Some are more suitable for making porcelain clay, while others are traditionally used for glazes.  It is difficult to know how similar modern-day porcelain stone is to traditional materials.  During the few years I have lived […]

  • Planeware

    Ceramics is not an independent craft, it has evolved in a complex environment of discourse with other craft traditions.  In Chinese ceramics this condition is reflected in the prevalence of skeuomorphisms, with ceramic vessels emulating the forms and manufacturing artifacts of more “valuable” metalworking traditions including bronze, silver and gold. The Planeware series is an exploration of the […]

  • Paperclay: Art and Practice

    My work is featured in Rosette Gault’s new book on paperclay.  I should note that only some of my work uses porcelain with small additions of paper.  Porosity is a big issue when making functional ware, and additions of paper can cause all kinds of problems.  In the past I tested cone 6 stoneware bodies […]

    In the future I’ll be adding articles to this website.  The first article that came to mind was a review of an excellent pyrometer I recently purchased, the Omega HH506RA.

  • 纪录片《china-瓷》

    It’s said that you can tell how long a foreigner has been in China by the number of appearances they have on Chinese television.  I’m not doing well, I guess, because I’ve only been in one documentary.“China · porcelain” is a documentary about the fascinating history of Chinese export porcelain in the Ming and Qing […]
