This analysis is one of many given in Notes for Potters in Australia, by
Ivan McMeekin:

Average of 10 analyses of New South Wales (Australia) eucalypts:
SiO2 30.1
Al2O3 2.1
Fe2O3 2.6
MgO 13.3
CaO 21.7
Na2O 10.4
K2O 10.8
MnO 0.6
P2O5 3.8
SO3 4.0

I don't know if the book is available in the USA. It's published by the New
South Wales University Press.
