As usual, I find the bottoms of bowls almost more handsome than the rest. 
One great addition this firing was the use of Bauer Orange Flashing Slip: 41.9 EPK
41.9 OM 4
5.7 Borax
10.5 Zircopax
Apply very thinly to bisque. Works on greenware, too. Do not apply over glaze.

What we learned in this firing is that using two 5 gallon buckets of clay and door mud and sealing the #$%^ out of the kiln door creates a massively intense reduction atmosphere -- there is no way except through the burner ports that oxygen can get in the kiln. This has the effect of making the 750 brown clay body very dark with iron spotting and lots of steely gray "carbon trapping" in areas that get blasted with sodium glass from applying the sodium carbonate mixture.
