    ANSWER is we have a phase rule of P+F = C+2 P= phases out if minimum no of components C= components minimum no of chemical constituent which makes all the phases . Components are generally of oxides I have listed below. 2 = indicates the Temperature and pressure are variable . if isobaric or isothermal condition we take it becomes 1 F = degree of freedom.

    Diagramtically it's bit complicated to explain without verbal talk

    that means it's same as phase rule used in igneous systems... and instead of binary system diagrams we have ACF and AKF diagrams?
