Marble

Is formed by metamorphosis ( that means “change in form”) of limestone and dolomite. The change is caused by heating and squeezing and melting deep in the earth.

It is often used for decorations in buildings and for sculptures because it is easy to carve.

Pure white marble is formed when the original stone was very pure. Colors, veins and swirls are due to various impurities in the original rock.
