There is a story to this firing:
This is the vase shown in the first photo before firing.
It has been painted with ferric chloride, sprinkled with sea salt, and had a few horse hairs placed on it. It will be loosely wrapped with the aluminum foil it is sitting on and placed in the barrel.
Pots are carefully placed in the "high-tech kiln". One of the guild members is adding dried banana peels to the mix. The blue substance is Miracle Gro. The amphorae are mine.
