Caption: Beltmoss Quarry, Kilsyth, Strathclyde.
Description: A series of narrow holes are drilled a few inches apart using a pneumatic drill. A series of hammer blows are delivered on the wedges in succession so producing a straight split in the block. This process is essentially the same as the 'plug and feather' method of splitting granite illustrated in the photographs of the Silver Grey Quarries, Creetown (C03736-C03737). Fashioning kerbs from quartz-dolerite. Large slabs are first broken into more manageable blocks by drilling and wedging. Note the colour of the fresh rock in the blocks to the left, contrast it with the thin yellowish exterior of weathered joint faces.
