Description: Albany Slip Substitute
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.
Fired at cone 01, 02, 03, 06 (top to bottom).
Albany Slip successor - a plastic clay that melts to dark brown glossy at cone 10R, with a frit addition it can also host a wide range of glazes at cone 6.
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.
