Marble is often confused with granite but is only similar in that they are both stone. Marble is a metamorphic stone made over millions of years under great pressure. Most marbles are made of metamorphosed, or somewhat fossilized, sedimentary stone. Marble is calcerous and, therefore, less hard and susceptible to acids and scratching.
While marble is occasionally used for kitchen counters, it is not advisable. Marbles are suggested for fireplace mantels, hearths and surrounds. Columns, furniture tops, backsplashes, and vanities are other excellent applications for marble.
