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.
