Salt Glazed Texture
Salt glazing
is a firing process in which pottery is engulfed in a sea
of sodium vapor
and fire.
Salt is
introduced into the firebox of the kiln at 2000 degrees.
The intense heat releases sodium from the salt,
which then fuses with the (clay) pottery,
making a glass surface.
The entire process is referred to as "vapor
glazing".

Wad Marks
The process
of salt glazing, and wood firing, naturally creates glazed surfaces on
pottery, but also coats the shelves where the pottery is stacked in the kiln.
Wadding
prevents pottery, 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. |
