What’s in a Celadon, anyway?

amaco celadon glaze

Over the last few years, as the glazes for Cone 5 and Cone 6 has expanded so much Amaco, Coyote, and Spectrum have introduced mid fire Celadon glaze lines. It made me start to wonder, “what exactly does it mean to be a celadon, anyway?”



Gita working towards her BFA at Metropolitan State University in Denver and has taken several advanced ceramic classes recently. I asked her to tell me more about Celadon glazes. 🙂

Shards of pottery with celadon glaze have been found in the Eastern Han Dynasty of China dating back to 25-220 CE. Even though its origins are in China, the sought after glaze spread throughout Asia, including Japan, Thailand and Korea. Traditionally, celadon glaze is a translucent green ranging from a pale green to a deep jade. Though these shades of green are the most coveted, celadons come in a variety of colors including grey, blue, yellow, and white depending on the thickness of application, the type of clay used, and the chemical makeup of the glaze.
Celadon glazes are traditionally fired in a reduction atmosphere because the transformation of iron oxide from ferric to ferrous in the oxygen poor environment is what creates the delicate palette of colors found in celadon glazes. Unfortunately, not all of us potters have access to a gas kiln or maybe we don’t want to deal with quite such a large undertaking in a private studio space. This leaves the option of firing in an oxidation atmosphere in our electric kilns. There are some really lovely cone 10 oxidation celadon recipes available but if you don’t have the space or the time to mix your own, you should consider the array of cone 5 commercial celadons available.
Currently Amaco, Coyote, Mayco and Spectrum all produce lovely celadon lines, each with their own take in a wide variety of colors. Many of these glazes are mixable within their line or other lines from the same manufacturer. They also are perfect for accentuating texture and carving. Add dimension to your work by experimenting with the new incarnation of an ancient glaze tradition.
