Pouring Vessel

Gas firings are interesting because, as the potter reduces the amount of oxygen entering the kiln, the fire gets the needed oxygen from the glazes.  Removing oxygen from the glazes changes their color.  The firing goes to about 2300 degrees Fahrenheit and takes about 12 hours, during which the kiln must be watched at all times. The kiln is then cooled for about three days and finally opened.  I especially love ancient Asian celadon glaze recipes for this kind of firing.  These glazes are made with red iron oxide but when the fire removes oxygen the glazes, the red changes to a luscious, soft blue or green.  I think these glazes are beautiful!
