The Clayboard by Cool Tools offers a smooth Teflon surface that metal clay won't stick to. The board features non-skid feet so your work is up off the table and the board stays where you put it. The tough Teflon surface can be used for rolling and assembly. The Clayboard Teflon surface is easy to replace if it becomes worn over time. Our Clay Thickness Rolling Frames work perfectly with this surface. Place the Rolling Frame of your desired thickness on the Clayboard, place your clay and in center and roll for perfectly calibrated sheets.
