   Metalstone Technologies, Inc. specializes in preventive building maintenance. We are committed to giving you

the best quality care, craftsmanship and service in maintaining your metal, stone, ceramic and wood surfaces.

   Because of it’s combination of strength and beauty, stone has been used since the beginning of time in buildings all over the world. Metalstone Technologies, Inc. will restore and maintain all of your favorites: granite, marble, travertine, and limestone.

 

Granite is a coarse-grained igneous rock made up of feldspar, mica, and at least 20 percent quartz. Granite is usually whitish or gray with a speckled appearance caused by the darker crystals. Potash feldspar imparts a red or flesh color to the rock. Granite crystallizes from magma that cools slowly, deep below the earth’s surface. Granite, along with other crystalline rocks, constitutes the foundation of the continental masses, and it is the most common intrusive rock exposed at the earth’s surface. Granite has greater strength than limestone and marble and is more difficult to quarry.

 

Marble is a form of limestone transformed through heat and pressure into a dense, variously colored, crystallized rock consisting primarily of calcite and or dolomite. Pure calcite is white, but mineral impurities add color in variegated patterns. Hematite, for example, adds red; limonite, yellow; serpentine, green; and diopside, blue. Commercially the term marble is extended to include any rock composed of calcium carbonate that takes a polish.

 

Travertine is a whitish, porous or crystalline mineral form of calcium carbonate, deposited in layered formations by hot and cold spring waters. The compact variety of travertine has been used as building stone since ancient Roman times.

 

Limestone is a sedimentary rock formed from the skeletons and shells of ocean organisms that consist mainly of calcium carbonate. Limestone is usually white, but with impurities such as sand, clay, iron oxides and hydroxides it can be found in almost every color. When limestone undergoes metamorphism (long-term heat and pressure), it turns into marble. Limestone is an important building stone in many parts of the world where the relatively soft nature of the stone allows for decorative carving.
