Instructions

This glaze is from Greg Daly's book, Lustre.

The test tile is B-Mix, fired in oxidation and re-fired in a reduction atmosphere.


This glaze needs to have a post-fire reduction to get its incredible iridescence.  Blue stripe on test tile is acid-etched.  Original recipe called for cobalt oxide but cobalt carbonate was substituted.
