Before working with clay, I had no idea that celadon is both a family of glazes as well as that particular green we all know and love. I ordered a sampler of Coyote cone 5-6 celadons, named "Franks Celadons". I found the name funny...but the glazes are seriously delicious. And with names like rainy day and stormy sea, they are that much more appealing. So, thanks Frank. Whoever you are.
