Igneous rocks are rocks from the mantle or crust by melting or partial melting of the material such as magma cools consolidation formation, granite is an igneous rock; sedimentary rock is not too deep in the  wet saw blades ground where the other rocks and some volcanic weathering products ejecta, moving through water or glaciers, sedimentation, diagenesis rocks, limestone and sandstone fall into this category; rocks and minerals at high temperature and pressure under the action of a mixture of natural deterioration from one stone to another stone, marble, slate, quartzite rocks belong.
Granite is a very hard igneous rock, its high density, resistance to scratches and corrosion. It is ideally suited for flooring and kitchen countertops. There are hundreds of varieties of granite.
Marble is a derivative of limestone, marble, a metamorphic rock can be polished. Marble has a soft easy to scratch or turbo diamond blade  acid corrosion. Around the world there are countless types of marble.
Limestone is a sedimentary rock is composed of calcite and sediment composition, forming a variety of colors.
Sandstone is a sedimentary rock, which is mainly composed of loose particles of quartz sand, rough texture, sandstone, there are many varieties to choose from.
Travertine is part of the metamorphic limestone, due to its structure, can fill, you can polish and high density, it has become one of the marble.
Slate is a metamorphic rock, original rock was muddy, silty or neutral tuff, management direction along the plate can peel into thin slices. Slate color with impurities they  12 inch saw blade contain varies, iron is red or yellow; carbonaceous for black or gray; calcium can cause foaming in case of hydrochloric acid, so named for the color of its general classification, as will green slate, black slate, calcareous slate.
Artificial stone is a mixture is made of non-natural, such as resin, cement, glass beads, aluminum powder, etc. plus gravel adhesives. Artificial stone (also known as "artificial marble"). Artificial stone came 30 years ago in the United States, one of the earliest applications of artificial stone as a decorative material is the mid-1990s a number of coastal cities, a few years after the widely popular.
