Manufacturer says: C-Red is a fine grained, iron bearing, plastic clay. Great for throwing bodies or anybody where warm color and plasticity is desired. Like all our milled clays C-red is air floated.

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.

Physical data can be found on the link to the product information web page of the manufacturer.

Industrial Minerals states: Due to the variations of natural occurring clays and minerals which limit our quality control and the variety of applications for our products over which we have no control, our products are sold with the understanding that the user is solely responsible for determining suitability for any purpose.
