The pot and additives are wrapped like campfire potatoes using a double layer of heavy duty aluminum foil being careful to seal it tightly. Fire the kiln up to anywhere between 1200 F to 1450 F.  When you see the foil is dull rather than shiny, possibly puffed up, it is done. If you over fire the foil, the colors may be lost.
