The system describes
the glaze in terms of the proportional relationships between the
flux group of oxides and other oxides.
In the example
formula in the chart for every one molecular part of flux oxides
their is 0.4 Al2O3 (alumina) molecues, 0.1 B2O3 (boron) molecules,
2.6 SiO2 (silica) molecules and 0.2 (titania) molecules.
that the molecular parts of the flux group of oxides total one.
We can therefore
refer to the following molecuar ratios:
to Al2O3 ...........1 : 0.4
to silica ............1 : 2.6
