Expanding Your Palette in Mid-Range Firing

Posted On December 14, 2010 5 Comments

Many people may be thinking about switching their firing method from high-fire to mid-range. For instance, students who recently graduated and lost access to school gas kilns, people with a day job and those who work in their garage studios, or production potters who are concerned about fuel conservation and energy savings. This reference is intended as a tool for those people to start glaze experimentation at mid-range that can be accomplished with minimal resources.

Technofile: Glaze Fit

Posted On May 5, 2010 2 Comments

Though many are unaware of it, poor glaze fit can reduce the strength of a fired ceramic piece to as little as one-fifth the strength of a similar piece with ideal glaze fit. While good glaze fit seldom occurs by accident, it can be planned for and controlled. Some ceramic artists use glaze fit to induce crazing as a decorative technique (crackling) while others artists may want to avoid a “crackle” glaze.

Critical Care: The Art of Self Critique

Posted On March 1, 2010 11 Comments

I use one tool everyday, on every pot or sculpture, whether I made it or not. This pervasive tool is critical analysis, and I use it to assess the pot I am currently throwing, the work I made yesterday and the work I made years ago.

How Glazes Melt: In Search of the Elusive Eutectic

Posted On December 9, 2009 2 Comments

Phases are specific forms of materials. The most familiar phases are solid, liquid and vapor. Any phase of a material is identical in composition and structure in all parts of that phase. For instance, a glass of water is the liquid phase of H2O, top to bottom; if it weren’t, we’d call it something else, like ice if it were solid (structural change), or lemonade if it had lemon and sugar dissolved in it (compositional change).

Posted On December 9, 2009 3 Comments

As a studio artist, it is often hard to spend large sums of money, even if doing so would pay off in the long run, so glass artist Hugh Jenkins set out to determine just how well he could do with a home-built heat recuperator.

Of all the well-known Japanese ceramic artists of the past four hundred years, men like Raku ware’s Chojiro, the Kyoto designers and decorators Ninsei Nonomura and Kenzan Ogata, and the innovative and technically brilliant Kozan Makuzu, by far the most famous and influential has been the twentieth century folk craft (mingei)  movement potter Shoji Hamada (1894-1978).

Landfill Gas and Alternative Fuels

Posted On December 7, 2009 0 Comments

Significant cost savings can be realized by potters without access to a landfill through a variety of strategies and fuel choices. These can be divided into categories and discussed in terms of benefits and difficulties. Solid fuels are difficult, liquid fuels are moderate, and gases are easier.
