Salt Glaze Process
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 or pottery, making a glass surface.
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 and leaves off white marks on the surface of the pots. 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 behind flame flashing patterns on the surface of the pots.
