I hope this damage at least allows DoC staff and NZHPT people to make a good record of and interpretation of the construction of this kiln.

The craftsmanlike and very attractive outer stone skin belies the inner chaos of rubble fill and what appears to be an unlined inner furnace. Surely the furnace was lined with fire bricks ?

The material between the outer wall and furnace surface is substantially made up of small stone and fine (limestone) which would have made logistic sense at the time but this material would particularly have transmitted non-reversible expansion force initiated outward movements. Without restraining bands in tension, a kiln like this is going to have a limited life - earthquakes or no earthquakes.

I hope to follow up on the interpretation of the furnace lining shortly.
