Lincoln Fireclay is plastic, it can be thrown on a potters wheel
The left two were made from a 100% mix of Lincoln 60, the right one adds 2% bentonite (Lincoln 60, by itself, matures into a stoneware at around cone 8). While it was possible to throw the pure material, the plasticity is a little lower than a normal pottery clay. That being said, it is smooth and has a soapy feel that makes it very pleasant to work with. A simple 2% addition of bentonite transformed it into a delight to throw! That only increased the drying shrinkage by about 0.5%.
