Ephraim’s Journey with Functional Glazes and More

Making pottery requires great fortitude and courage. Six years ago we switched from our earthenware clay body to a stoneware clay body, which would support the studio in developing a line of functional pottery over time. Concurrently, the new stoneware clay body would sustain Ephraim’s existing and ever-evolving line of art pottery. Many of the studio artists began their potting careers as functional production potters and enjoy the idea of returning to their roots in functional ware. This leap initially required our glaze chemist to reformulate all of the production glazes so they were compatible with our new clay body a huge endeavor!

As our standard production glazes stabilized, the shift in materials generated new, innovative techniques for glazing pottery. It laid a foundation for us to formulate a new line of glazes from scratch that were fired at a higher temperature and suitable for functional ware.

Glaze Development – Midfire Glazes

Just like staring at a blank canvas with a palette full of paint, setting out to design a new glaze line can be daunting. It forced us to imagine how we wanted these glazes to look and feel:

  • Should they look like our earthenware glazes?
  • Should they relate to each other?
  • Should they be entirely different from our signature glazes?

These were all questions that we would explore in great detail over the coming years.

Three long years of testing ensued that yielded several complete failures, along with a portion of promising results. From this humbling experience, we firmly concluded that these functional glazes had to not only be pleasant, but extraordinarily beautiful. Indeed, beautiful enough to eventually hold their own beside the masters of mid-century ceramics that we deeply admired. With each glaze test we were reminded that while making art is academic and inspiring, it is equally hard and requires extreme patience.

Inventing a beautiful, stable and functional glaze turned out to be a fraction of the development necessary to bring our vision to life. We still had to develop methods of applying the glaze and firing the pieces that also looked beautiful. From dipping, to spraying and everything in between we tried countless methods to achieve the stunning look we were after.

 

In addition, we needed to extensively explore the perfect form for these functional pieces, one that served as an elegant and refined canvas for our elegant, functional glaze. Coffee mugs in every shape and size imaginable were created and, over the course of a year, friends and family were surveyed to evaluate the most compelling coffee mug features. Our first functional offering is indeed a coffee mug, the Cauldron Mug, presented in October 2018. The form features a thin rim, subtle break in the main body form, and comfortable large handle with a modern, elegant foot. The form shows off the feathery, buttery glaze perfectly and we couldn’t be more proud.

The journey goes on as we endeavor to create bowls and more mug designs in 2019, continuing to use our experiences, good or bad – failure or success, to move us forward.
