Salt Glazed Texture
Salt glazing
is a process where pots are engulfed in a sea
of sodium vapors and fire.
Salt is
introduced into the kiln at 2000 degrees, releasing sodium which fluxes
silica and alumina in the clay body. This action creates a unique glaze.
The entire
process is called "vapor glazing

Wad Marks
Sodium (salt
glazing), and fly ash (wood firing), create glaze on pots, and on the kiln
shelves where pots rest in the kiln. Wadding prevents pieces, from fusing to
the kiln shelves.
The size, shape and materials used for wadding,
are important aesthetic considerations for the potter. In addition to
preventing pots from fusing to shelves, wadding acts as a color resist and
leaves flame flashing patterns
