Salt glaze mug vertical wiggle and horizontal banding

Stoneware mugs fired in our new salt glaze kiln. These mugs have had pattern and texture added to them to bring out more interest in the surface, which is unique to the salt glaze technique. The finish is varied as the salt vapourises and moves through the kiln hitting some things more than others. It will be pot luck (no pun intended) as to which one you get but they will have the same surface decoration on them.
