Split finish

Split face will normally have a dark blue-grey colour with random paler flecks where crinoids are present.  Splitting produces an irregular surface which amy have quite high relief.  Humps, hollows and pits will be randomly developed on the surface and may extend across the block edges.  Ashlar traditionally had a chisel dressed edge applied to the exposed face.  It will be necessary to dress areas of split stone using a point to remove the ivsible sawn edges.
