Notes
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.
Typical Sieve Analysis:
80 mesh: trace
100 mesh: 0.2%
200 mesh: 2.5%
Total Shrinkage
Cone 5: 12.3
Cone 10: 13.4
Absorption
Cone 5: 13.2
Cone 10: 7.4
