This is the chemistry of the material (the formula compares numbers of molecules, the analysis compares them by weight). In glazes, the composite chemistry of the mix is the main factor shaping fired properties (e.g. color, melting temperature, surface). In bodies we are interested in their physical properties (e.g. shrinkage, porosity, strength), these are a product of the mineralogy of the materials.

The manufacturer describes it as a fine-grained engineered blend offering excellent bonding and forming characteristics. Ideally suited for extrusion, dry and wet pressing applications. This material is an alternative to, for example, OM#4, it has a lower coal content and fires a little lighter in color.
