Notes

Lincoln fireclay has a smooth and very pleasant feel and is used as a major ingredient in many commercial west coast USA stoneware and middle fire clay bodies. It is quite fine, 99% minus 100 mesh, 97-98% minus 200 mesh. It provide excellent drying properties considering its high plasticity.

Although this material is called a fireclay by many, it is not. It matures around orton 10, reaching zero absorption at that point.
