This body is a plastic fireclay base having 13% 20/48 grog and 10% 65 mesh silica sand. But the texture is far coarser than one would expect. That is because it has 4 cubic feet of perlite per thousand pound batch. If desired the surface can be trowel smooth. This works well partly because the perlite particles are soft and easy to crush.
