Description: Beltmoss Quarry, Kilsyth, Strathclyde. Fashioning kerbs from quartz-dolerite. Placing wedges before splitting the block. A series of narrow holes have been drilled a few inches apart and wedges inserted. Using the large square-faced hammer a succession of blows will be given to each wedge in turn causing the block to separate in a clean split. On the top face are the remains of four previous drill holes, evidence that the rock has been split in that direction previously. 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).
