Notes

Originally referred to as FAST CAST, F.C. Clay is a secondary, coarse grained Georgia Clay with a particle size distribution approaching that of fractional clay. The chemical analysis is close to that of theoretical kaolinite. Uniformity, excellent color, low C.E.C., surface area, ease of dispersion and coarseness are notable characteristics. It is available in lump, dried, airfloated and slurry forms.
