Alberta Slip is a great base for black glazes at cone 10 reduction, only 1% black stain is needed to obtain a jet black glossy. Increasing amounts of stain up to 5% move toward a matte black for Mason 6600 (they remain glossy for Mason 6666). Adding 5-10% black stain and 5-7% iron produces a crystalizing intense gunmetal black. Mixtured additions of Mason 6600:6666 (e.g. 1:1, 2:2) produce metallic surfaces.

Like other high-percentage Alberta Slip glazes, you must use a mix of calcined a raw powder. See the preparation page at for more information.
