Note the bottle protruding from the kiln lining at top right. This is a temporary stopper for one of the high level “pigeon holes” which are used as spy holes and for some sidestoking. The sidestoking in these ports is for atmsopheric control rather than for producing ash deposits. The tiles in the picture below show the construction of “the wall”, a structure across the kiln which is rebuilt for each firing. It has openings for flame passage at the bottom and is designed as an obstacle to slow the flames and draw them down to the bottom of the chamber. The new sidestoking port shown under construction here is immediately uphill of the wall. |
