Stone is a great floor finish and is affordable in many countries; Italy and India are both known for the variety and quality of stone they produce. There is a great advantage to stone that is almost unique to floor finishes: you can polish it, and thus make it look and feel like new, at any time in its life.
Granite is a volcanic rock (it was originally lava that cooled to form solid rock) that has the following properties:
• It is very hard, strong, and abrasion resistant
• It is resistant to acids
• It can be polished to a mirror-like smoothness
These properties make it a great choice as a floor or countertop finish. It can also be used to clad walls. However it is available mainly in dark colours: black, red, grey. This darkness in colour does tend to limit its use in certain areas. Its surface can also be worked to produce a variety of textures other than smooth.
These rough finishes are mostly used outdoors, on pathways. The famous cobblestones of Europe are granite, for instance.
Marble is a metamorphic rock (meaning that it was made by the intense pressures and heat deep within the earth), and has the following properties:
• Most marbles are soft, and not very abrasion resistant
• They are not resistant to acids
• They can be polished to a mirror finish
• It is translucent - light can pass through it to the extent of a few millimeters
Thus, marbles should not be used in high-traffic areas such as the entryways or staircases of public buildings - granite would be much better in those cases. Since it is not acid resistant, you should not use marble under urinals (urine is acidic), and in kitchens, where lemon juice and other acids are present. But marble is prized for the beauty and richness of its finish; it also feels very special underfoot. It is available in a wide variety of colours, mainly light colours.
Sandstone is a sedimentary rock (rock formed by ancient rivers that slowly
deposited material on their beds, that built up layer by layer over millions of years). It
has the following properties:
• It is abrasion resistant, but not always strong, as it is formed in layers.
• It is usually highly resistant to acids
• It has a rough finish, and cannot be mirror-polished, as it consists of grains
These properties mean that it is good for decks and external areas because of its anti-slip properties. Since sandstone looks and feels very different from granite and marble, it has become fashionable to use these in boutique stores. Steve Jobs famously saw a bluish-grey sandstone on a trip to Florence, and many years later insisted that that very stone be used in all apple stores because of its 'integrity'. The stone is quarried, cut into tiles, and every piece graded individually for colour tone by master craftsmen. The tiles are then arranged so that pieces with similar colour are placed together, which makes them seem more uniform to the eye.
