Woden Firing 47

Level by level images of Bill's pots as they were loaded in the back section.

Trying to leave spaces and height for the hot air and flames to circulate during the firing.

The lowest level has the unfired, unglazed urns, in the coolest part of the chamber, where glazes tend to be underfired. The unfired pots need to be heated up slowly to start with, to dry them out carefully - or they will explode as the steam is generated.

The pale unglazed surfaces will turn much darker during the firing, as the iron oxide in the clay is reduced - oxygen is removed from the oxide to produce a darker coloured oxide with more iron and less oxygen.
