The Roman Empire
This kiln must be the beginning of the Roman Empire. We have two small arches laid and 8 more to go. 2 Arches over the fire starter, 3 arches for the grates, arch over stoke door, arch over firebox, two arches for the throat and of course the arch over the pot chamber. 10 arches in total. Perhap this kiln ought to be named Archie.
