Description: | Here is seen the lines of bedding called by the workmen 'rives' which determine the thickness of the flags and the joints called 'backs' which decide their area. 15 feet by 15 feet is the largest slab that can be got. Owing to the 'bate' or line of cleavage the ends have to be sawn off. [Diagram with A, B, C, D] AB line of rive or bedding plane, AC is the bate or cleavage plane. |
