I finished the final glazing on the art bra piece last night and fired it with help from Lisa Dawn and Scott Galbraith. They did some nice brushwork with some of my specially formulated silver nitrate glaze on the scales of the piece with the dragon head. It was a long night of epic adventure fraught with great peril. We werent able to open the reduction chamber until moments ago. Had to wait for the chamber to cool from 1850 degrees to room temp . And so we waited until this afternoon to see if they shattered under the stress which often happens due to massive thermal shock inherent in the Raku process. This firing technique deposits thick smoke tar on fired pieces that has to be scrubbed off in order to determine success or failure with the glaze colors. If oxygen gets to the Raku fired piece before it cools to 400 degrees, all color glazes revert to muddy brown. And so it turns out the pieces survived the thermal shock and stayed protected from oxygen contamination under layers of carbonized sawdust & paper. SUCCESS!!!! I can finally get a good nights sleep after weeks of working on this project. Soon I will start the leather and metal work to turn it into a functional dragon bra. :-D
