A bstract A method is given for correlating the chemical composition, relative amounts of glassy bond, and properties of fired ceramic bodies. The procedure consists of (1) plotting the compositions expressed in simplified terms on a reference diagram and (2) plotting data on the physical properties vertically from the plane of the reference diagram. Because the reference diagram contains the appropriate equilibrium diagram, the quantities of liquid and crystalline phases calculated for preparations of pure raw materials heated to equilibrium at a given temperature are useful (1) in estimating the relative quantities of glassy bond in fired bodies and (2) in differentiating fired bodies with respect to phase constituents. Data on fired whiteware are used to illustrate the relation of composition to the following properties: porosity, shrinkage, dielectric strength, and specific gravity.
