Marble is a metamorphic rock formed from the recrystallization of
limestone under intense pressure and high temperatures within the earth.
During this process, other minerals are introduced into the structure,
which produce beautiful colors and veining which characterize marble.
Marble colors vary from white to black, being sometimes yellow, red and
green, and frequently beautifully veined or clouded. Marble is scratch-
and stain-prone, as it is not as hard as a granite surface. It is not
preferred in the kitchen, but works well in bathrooms, on hearths, and
in some furniture applications.
