Metamorphic stone originates from a natural change from one type of stone to another type through the mixture of heat, pressure and minerals. The change may be development of a crystalline formation, a texture change, or a color change.

What’s the difference between marble & granite?
Although both are stones and both are quarried from the earth, granite and marble (and marbles relatives-limestone, onyx and travertine) are very different from each other. Granite is formed deep in the earth’s mantle at extremely high temperatures, and is a very hard, resistant stone made of crystallized minerals.

The marble family-limestone, travertine, marble, onyx-starts out as sediment-animal skeletons and shells, plant matter, silt-at the bottom of bodies of water. After millions of years this solidifies (lithophytes) into stone. Because it main component is calcium, it can be affected by acids such as vinegar and citrus beverages.

It is necessary to seal stone?
All stone, even granite, is porous to some degree, and will absorb stains over time. Some stones are more porous than others, so it is important to use a penetrating sealer to prevent stains from oil, wine, or other liquids from soaking into the surface. Go to Stone Maintenance.

Do I have to buy the whole sheet/slab?
Slabs are always sold intact. Buying random slabs is similar to buying fabric. Like a seamstress or tailor, your fabricator buys the raw material and sells you a completed installation. In the price is included the cost of transporting the material, making field measurements and templates, cutting, polishing, bringing the pieces to your job site and fitting them into place. How much material he needs is determined by the layout and the amounts of waste. The fabricator will lay out your job in a way that will minimize the amount of waste material while maximizing the natural beauty of veining and pattern.
