This is one of the pieces I threw while at the Fair at the beginning of this month. It is a vase with four Koi fish carved in a water pattern. You are looking at the head and body of one of the lower ones. I use a brown glaze that is brushed on over the carved areas, then sponged off. Then a dip into a light blue glaze. That is followed by brushwork with an orange glaze over the fish bodies. You can see the iridescence that happens when the overlapped glazes pool. The blue glaze is fat and creamy, with tiny bubbles under the surface that reflect light. I think this is as close to a Chun glaze as I will be able to get with the way I am firing. One of the descriptions for a Chun glaze is "a milky, opaque finish where tiny bubbles are clearly present"
Well, sorry about the link. I have tried to get it to work about 4 times. Try this and see if it works for you. Otherwise, just google Chun glazes. http://www.websitetoolbox.com/tool/post/clayarts/vpost?id=1716193
