Ceramic Brains- What say You?

This morning I threw a couple of saggars for Sheila's boxes. She likes the look of our dry ash glaze best on the inside of the box. The outside especially where thick fluxes and she is convinced it is the atmosphere created from the burners. We are going to try to saggar the pots.She likes dry and crusty which could have been her attraction to me.
One thing I've discovered with doing this blog is that it is strangely enuff potters that read it. Whodda thunk it??? Any ideas on this hypothesis of saggared glazes!
