We unloaded the kiln yesterday, and the firing seemed pretty successful. I had a couple vases pinhole with our matte black glaze. The glaze probably needs to be fired a little hotter, or soaked longer.
Loaded the kiln tonight to be fired again tomorrow. Seems like each cycle we end up with enough pots to fire several times- back to back. This also allows us to get into a 'glaze groove'! Here's some pics from our first firing.
