A very high iron refractory clay well suited for many ceramic applications requiring bright red color. It fires to a toasty red up to about cone 3 and then turns dark red to brown (partly due to soluble salts on the surface that darken the color). This material has a plasticity similar to a typical pottery clay body. Carbondale red provides formulators with an economical source of iron oxide.

Some have suggested this as a substitute for Newman Red, however it is much more vitreous and higher in iron.
