Dimension stone converted to dimension stone production. However, first the stone shattered by heavy and indiscriminate blasting must be removed. Dimension stone is separated by more precise and delicate techniques, such as diamond wire saws, diamond belt saws, burners (jet-piercers), or light and selective blasting with Primacord, a weak explosive. A variety of igneous, metamorphic, and sedimentary rocks are used as structural and decorative dimension stone. These rock types are more commonly known as granite, limestone, marble, travertine, quartz-based stone (sandstone, quartzite) and slate. Other varieties of dimension stone that are normally considered to be special minor types include alabaster (massive gypsum),
Cottonwood Limestone its region can often be recognized by the use of large cut blocks, near-white or buff color, and showing abundant fossils or molds of “wheat-grain” shaped fusulinids coupled with general absence of spalling, splotchy black coloring from mold that find portions of the stone particularly favorable, and sculptured or protruding rough faces. Especially in older buildings close to a source, Cottonwood Limestone is sometimes paired with the Neva Limestone that is commonly exposed only 35 feet lower in the hills. In this combination, the softer, massive Cottonwood is used for carved trim while the Neva is used, cut or rough,
