Notice how ware is set on pads of clay to enable the salt vapours to access the underside. Salt and soda kilns degrade over time as the sodium eats away at the interior bricks. Shelves must be covered in kiln wash to preserve them.
Salt firing is a process where unglazed ware is fired to high temperatures and salt is introduced to produce a vapor that glazes the ware.
