Unity Formula


A unity formula is just a formula that has been retotalled so that the RO group of oxides total one. This is also called a Seger formula and this standard provides the basis for comparing glazes. The three column format of expressing a formula was first used by Hermann Seger. The unity is normally set to the fluxes. Here is how we would recalculate the above raw formula to a flux unity formula:

           Raw              Unity
Oxides Formula Formula
-----------------------------------
K2O 0.6 / 2.20 = 0.27
CaO 1.3 / 2.20 = 0.59
MgO 0.2 / 2.20 = 0.09
ZnO 0.1 / 2.20 = 0.05
----- ----
Flux Total 2.2 1.0
Al2O3 0.9 / 2.20 = 0.41
SiO2 9.0 / 2.20 = 4.09
