The second article will complete the account of granite quarrying. The final two articles concern the process of finishing granite and will conclude with a discussion of power sources, toolmaking, patents, granite workers, labor unions, and safety and health issues. The four articles will appear in consecutive issues of The Chronicle. Granite Composition ranite is a very common stone found world-wide. Figure 1. Distribution of granite and allied rocks in the United GGranite has been commercially quarried in the States. The three primary areas are the along the Appalachian United States, Canada, Scotland, Finland, Italy, Ukraine, Mountains on the east coast, Wisconsin and Minnesota in the Great India, China, and Africa. Granite is found throughout Lakes region, and California, Colorado, Idaho, and Arizona west of the Rockies. the United States and has been commercially exploited in every New England state (Figure 1). Granite is com- posed primarily of quartz and feldspar with smaller amounts of mica. Quartz contributes to granite’s strength, hardness, and luster, and acts as a cement binding all the elements together. Feldspar, granite’s principal ingredient, occurs in a number of forms, mostly sodium/aluminum/silicon-rich plagio- clase and potassium-rich microcline. In addition to contributing to strength and hardness, feldspar primarily determines granite’s color, resistance to discoloration and decay, and ability to receive a polish. Mica (mostly white muscovite and black biotite) is present in much smaller amounts. The rela- tive amounts of white and black mica are an important factor in both the color and commercial value of the granite. If white mica predominates, the granite will be light-colored, and if the black predominates, the granite will be dark, often approaching black. If the white and black occur in roughly equal amounts, the granite will be speckled. Since mica does not polish well nor does it retain its luster, excessive amounts of mica decrease the com- mercial value of granite. As an example, granite of the Barre, Vermont, area contains 31.7 percent plagioclase feldspar, 26.4 percent microcline feldspar, 23.3 percent quartz, 6.4 percent muscovite mica, 4.5 percent biotite mica, 2.7 percent orthoclase, 2.1 percent chlorite, and 1.6 percent calcite. Granite is an igneous rock, formed by high heat and pressure from mol- ten rock called magma. Deep magma over time forced its way up through Figure 2.

Marble, limestone, and slate are granite’s chief competitors. Marble is easy to rough out but difficult to finish. It carves beauti- fully and takes a sharp carved edge. However, marble does not stand up well out of doors since it dissolves, pits, and discolors in pol- luted air. Limestone is easy to work when freshly quarried, takes a sharp carved edge and weathers well outdoors. Slate is easy to work but due to its strong lines of cleavage is subject to flaking both while being worked and as it ages. Brownstone and sandstone Figure 3.
