was something entirely different - in a firing that was well reduced and
produced good carbon trapping with other glazes, this turned out pure white
and it crazed. Any ideas of what might be making this happen. The redart di=
d
go into it.

The last sentence answered your question: " The redart did go into it."
The redart being your primary source of iron.
