Blue Celedon on Matrix Limits Graphs
Matrix uses a number
of different types of limits graphs.
The graphs on this
page show the unity formula for Nicki's Blue Celedon registered
as yellow rectangles on the limits graphs set for C.12
This graph reveals
that the flux oxides for Nicki's Blue Celedon fall within the
range suggested by the limits for C.12.
The Al2O3 and SiO2
oxides are shown to be on the low side for this temperature particularly
the alumina content.
& SiO2 Limits C.12
This graph focuses
only on the Al2O3 and the SiO2 content of the glaze being studied.
While the SiO2 value
for Nicki's Blue Celedon is just below the recommended limit,
the Al2O3 content is well down.
