Questions about this item

Four shapes: a kidney, a crescent, a pointed rib and a straight-edge rib.

The largest is about 3.9 x 2 in; the others are a little smaller.

Compressing the floor of a pot to prevent S-cracks, smoothing thrown walls, clearing slip and refining curves without leaving marks.

Rubber flexes to follow curves and leaves a smooth, compressed surface. Wood is stiffer for shaping walls on the wheel. Many potters keep both.

They are made for clay. Keep a separate rib if you want to spread slip or underglaze.
