Material Origin and Qualities
Marble is a metamorphic rock derived from limestone, composed mostly of calcite (a crystalline form of calcium carbonate, CaCO3). The original source of the parent limestone is the seabed deposition calcium carbonate in the form of microscopic animal skeletons or similar materials. Marble is formed when the limestone is transformed by heat and pressure after being overlain by other materials. The finest marbles for sculpture have no or few stains (some natural stain can be seen in the sculpture shown at left, which the sculptor has skillfully incorporated into the sculpture).

Famous quotes containing the words material, origin and/or qualities:
“Since art is the expression of beauty and beauty can be understood only in the form of the material elements of the true idea it contains, art has become almost uniquely feminine. Beauty is woman, and also art is woman.”
—Rémy De Gourmont (1858–1915)
“Each structure and institution here was so primitive that you could at once refer it to its source; but our buildings commonly suggest neither their origin nor their purpose.”
—Henry David Thoreau (1817–1862)
“Man is by nature a pragmatic materialist, a mechanic, a lover of gadgets and gadgetry; and these are qualities that characterize the “establishment” which regulates modern society: pragmatism, materialism, mechanization, and gadgetry. Woman, on the other hand, is a practical idealist, a humanitarian with a strong sense of noblesse oblige, an altruist rather than a capitalist.”
—Elizabeth Gould Davis (b. 1910)
