Building stones of Edinburgh: quarrying methods -

James Gowans introduced a new technique which was said to be an improvement on the traditional wedging method at his quarry at Redhall in about 1850. A row of 7.5 to 10cm diameter holes of considerable depth was drilled at a suitable distance from the quarry face. These were then charged with gunpowder and fired simultaneously by an electric battery. The method produced a large amount of stone ...
