- Raw Mineral: No
- Generic: No
Notes
A very plastic ball clay of fairly high coal content. This material has some iron stone concretion material in it and thus it does contribute to some iron blossoms in cone 10R if not ground fine. RA2 has some soluble salts that produce a brownish surface coloration in reduction firing.
RA2 is similar to most commercial ball clays except that it has a higher iron content and it does not deflocculate well for use in casting slips due to the solubles content.
RA2 fires to a yellow to grey buff in oxidation and reduction.
