The Hit Parade: The Beat Goes On

May 10, 2015

Central Mosque Djenne 1984 Once again, a big thanks to Rob Hunter and his inspired Ceramics in America 2014 ‘top ten’ issue. 

If my "Hit Parade" were to be about looks alone, I might have included the creative slip applications of English Mocha ware, or the bizarre, twisted explorations of George Orr, or the brilliant cobalt blues of German Westerwald salt-fired stoneware, or the wood-fired stoneware of Richard Bresnahan with whom I did my apprenticeship, etc, etc. etc.

But the genius of this exercise is to explore pottery’s intimate walk with humanity through the ages.  And it invites musing on one’s own relation to this incredible field as well.  Narrowing that down to ten entries is challenge enough!

For example, I could have easily included the Absalom Steadman stoneware jug c. 1823 which received the highest price paid at auction for early American pottery, thus illuminating the status of historic pottery in today’s art economy.  The 1840 William Henry Harrison transfer print pitcher by David Henderson speaks volumes about the part ceramics played in the development of our national politics.  The 11th century Central Mosque in D’jenne, Mali is the world’s largest adobe clay structure.  (But what’s that silly tourist doing there?)  Potters for Peace’s Filtron water purifier project highlights the enormous contributions of pottery to rural community development efforts.  The black pottery of Maria Martinez offers a classic example of pottery and cultural revitalization.  And the curious parallels between Richard Bresnahan’s unique wood firing process and astro-physics is fodder for an entire book in itself.

Every picture tells a story.  So does every pot.  The thing is, when it comes to pottery history’s ‘top 10,’ the story itself is quite often where it’s at.

And the beat goes on

How I Learned To Hate Everything

August 31, 2014

(an editorial thinly disguised as a book review)

A group of potters went to see a “Blue and White” ceramics exhibit at a major museum in a large city.  During the trip, one of the potters lamented how she was taught nothing in college about America’s pottery heritage. 

Most of the potters in the group, being of more or less the same generation, were taught that Asian porcelain was pottery’s culminating expression.  Anything outside that narrative – excepting modern pottery – was background (ie; easily dismissed).  Gaping educational holes were partially filled as individual interests randomly wandered.

Daniel Rhodes defined the ‘official’ narrative during my own college years.  Rhodes’ Clay and Glazes for the Potter, revised edition 1973, was our class bible.  (Boy, am I dating myself!)  Just as important as the book’s technical information were its pictures.  I poured over them and absorbed their implied lesson – see the rest, end with the best: Song Dynasty Chinese Imperial porcelain.  We were certainly offered a generic overview of the ceramic spectrum, but the ultimate lesson remained.

The Rhodes book had two images of early American pots; A sgraffito plate by Georg Hubener of Bucks County, PA, c.1790, and a mass-produced molded stoneware pitcher in the form of a waterfall or whatever by the American Pottery Company of Trenton, NJ, c.1840.  Without context or hint of other efforts, and compared to those oil spot and celadon glazes, I concluded, “no thanks.”

That “no thanks” attitude wasn’t so much like comparing apples to oranges as it was like believing apples for eating were “better” than apples for making cider, or for baking.  But why compare at all? 

Of course, Daniel Rhodes can’t be all to blame.  There were (are) plenty of books about all sorts of pottery types.  And yes, old Chinese porcelain deserves respect.  But we were poor college students.  The pictures in Rhodes’ book and the resulting chatter around the studio were our gateway (there was no internet back then).  The range of early American (and European) pottery expression hit me only after some intense overseas time induced reflection on my own background.

If we’re never taught that something has value we can easily assume it has no value;  “History is boring!”  “Who cares?”  “Been there, done that.”

When did you first see beyond these ridiculous notions?

World Class Connoisseurs of Salt-Fired German Stoneware

May 4, 2014

They say Germany’s two greatest contributions to Western Civilization were the Reformation and hops in beer.  And both happened at about the same time.

As condensed history, so it goes.  But hops also radically impacted pottery history.  Everybody wanted beer once early 16th century brewers, village housewives mostly, began producing it.  Kids even got their diluted “little beer” for breakfast.  And the best beer containers, before mass produced glass, were stoneware bottles.  Demand skyrocketed.  Germans had been tinkering with stoneware since the 10th century.  But 16th to 18th century salt-fired German stoneware became world renowned because of beer.

Unfortunately Germany’s Rhineland district, where the best work was made, was a playground of war for centuries.  Whole communities were continually uprooted by chronic warfare.  Rhennish potters from Raeren, Freshcen and Siegburg ultimately ended up in the somewhat calmer Westerwald region.

Along the way they picked up improvements in clays, sprig decorations, and brilliant manganese and cobalt highlights.  Their work spawned off-shoots, reproductions, fakes and revivals long after their dominance had passed.

German stoneware was so popular, English potters couldn’t prevent caveats from diluting their July 22, 1672 Parliamentary Order in Council meant to insulate local markets.  The final bill prohibited imports of “any kind or sort of Painted Earthen Wares whatsoever except those of China, and Stone bottles and Juggs.”

Tons of German stoneware, literally, were shipped to England’s North American colonies during the 18th century.  Ironically beer bottles and beer mugs, “krugen” and “cannen,” were not the top imports.  Chamber pots were.  But drinking vessels were close behind.  And they were scattered almost as far.

Colonists weren’t the only admirers of salt-fired German stoneware, however.  Many Native American burial sites included Westerwald jugs.  When pottery is done well, there are no boundaries to how far it will be collected.

Adam Smith Wasn’t Always Right

February 23, 2014

In economics, success and growth walk hand in hand.  Except when they don’t.  George Henderson’s Dorchester Pottery Works in Dorchester, MA started as a large industrial stoneware factory but ended up flourishing as a small family run pottery.

George started the business in 1885.  His factory employed 28 workers who turned out “industrial” salt fired stoneware crocks, acid jars, etc.  George built a gigantic newfangled gas fired downdraft kiln in 1914.  It cost a whopping $250,000 and was one of only two of it’s kind in the nation at the time.

This situation presented George with a choice: continue with salt firing (and what salt would do to his phenomenally expensive kiln) or switch to glazed work.  Glazing meant either an Albany slip or a feldspathic Bristol glaze.  George opted for the Bristol glaze.

The British invented the Bristol glaze as an alternative to both lead and salt.  The off-white Bristol glaze used zinc oxide, calcium, feldspar, and china clay to create the world’s first eutectic “trick.”  That is, by mixing zinc and calcium (both requiring very high temperatures to melt), their combined melting point becomes dramatically lower.  Thus, Bristol glazes matured at low temperatures, speeding up firing time and lowering fuel usage.

America imported Bristol glazes since their creation in the early 19th century.  But potters at the New Orleans Exposition of 1884 were especially impressed.  Before 1920 Bristol was generally used in combination with the black Albany slip glaze.  After 1920, it was pretty much Bristol all the way.

When George Henderson died in 1928, his son Charles struggled with the albatross his dad left him. Demand for industrial wares plummeted during the Great Depression.  In 1940, Charles’ wife Ethel took charge.  Ethel scaled everything way back and switched to just tableware.  In the process, Dorchester became the first American pottery to fully develop the Bristol glaze’s potential for precise detail and extreme control of painted decoration.

For the next 40 years Dorchester turned out decorative tableware.  Many of their most popular designs came from customer suggestions.  Ethel and George were even able to retain a few of the Italian potters George’s dad had imported to work in the factory, including their principle thrower Nando Ricci.

Fire destroyed the building and the business in 1979.  But the Dorchester Pottery Works left behind a reassuring legacy; It’s ok to be small.
