glazing and firing the curvy vase, a four day process

the inside of the curvy vase is glazed first, the drips wiped off and the vases left to dry overnight. the outside is glazed the next day, again left to dry overnight
the vases are loaded into the kiln, and fired over the next twelve hours, going up to 2300°F. after reaching temperature, the kiln takes about eighteen hours to cool down before it can be opened
the glaze melts, and the inside color shows when the vases have been fired to 2300°F, you can also see how much the vases shrink in the firing, about 10%
