Interior of a groundhog kiln

Figure 17 shows the interior of a groundhog kiln during firing. Note the cherry-red color of the pots as the clay within them fuses together to make them hard and impervious. This is where the magical transformation of mud to stone occurs. This photograph is used here courtesy of Terry Zug, who took it through an observation port in Burlon Craig’s kiln.
