Robin Hopper offers in Appendix 8 of Clay and glazes for the potter revised,
of Rhodes some raku glazes with very high alumina , like this one
3195.................75
custer...............25
for 012-06

Did anyone try it ?
I think 0.5 mole alumina is pretty high for ^6 ox.
Do I learn something new?
