Thin sections of marble or like stone are made by sawing of a block to produce preliminary slabs which are held together, either by integral bridging portions, bonded base portions, or external shoring, while a spacer material, for example resin, is introduced into the clefts between the slabs. A second sawing operation then divides each slab into two halves, which can be ground and polished before separation.
