Notes

It is a low-melting iron stained clay (hits zero porosity around cone 1). Very plastic (11% drying shrinkage) and slow drying (Albany Slip, by contrast, is non plastic and fast drying). Alberta Slip is more plastic than Albany, but not nearly as plastic as this.

Clays that are not kaolins, ball clays or bentonites. For example, stoneware clays are mixtures of all of the above plus quartz, feldspar, mica and other minerals. There are also many clays that have high plasticity like bentonite but are much different mineralogically.
