Bi-Clay strips have curled during drying. But there is a problem.
The front bar was dried with the white engobe upward, the rear one with it downward (an EBCT test). While both have curled toward the red body, the front one has done so less. To enter the results we will average the amount of bend. But there is another problem. During rolling, the white body thinned more and is thus not as thick as the red. Thus there is question about whether the bend is because of this or because of higher shrinkage of the red.
