Product Overview

A medium-range stoneware body that mimics a gas-fired reduction clay body in oxidation. Warm medium black/brown color (NOT A TRUE BLACK CLAY). Not recommended for use in reduction.
Contrary to appearance, this clay doesn’t have any grog in it. Any lighter colored speckles in the clay are from the hawthorn fireclay, which is one of the clay based ingredients in the recipe. Because of the darker color of the clay body, the lighter particles of the hawthorn show up, especially after firing. Grog is often fired particles of fireclay, but after it’s fired the particles no longer shrink and no longer absorb moisture. But in a moist clay body, it kind of feels like grog and looks like grog. But it doesn't have the thermal shock reduction properties of grog and it doesn't make the clay dry and fire more evenly like grog would. 
Also check out the linked YouTube video, which shows Anne W holding a 5/6 Black cup held against a white wall, then Aardvark Cassius Basaltic, then Standard 266, then Nara Cone 5 porcelain. Anne M Bracker's voice can be overheard narrating. There aren't any fancy lights - only the fluorescent lights that were on in the room and there definitely isn’t any fancy production value.
