BASE: metal, black varnished. TOP FRAME: metal, finishes: black nickel or titanium, or oxy grey varnished. UPPER TOP: smoked glass. LOWER TOP: "Arabesque grey" marble. ATTENTION: marble is characterized by porosity and cracking that, during the manufacturing process are filled with special resins or inserts in the same material. After the polishing the surface may present irregularities and natural micro holes, which, however, do not compromise the solidity of the product. For the correct maintenance of all marble surfaces, it is recommended to use neutral detergents and no degreasers nor corrosive detergents. Acid substances may spoil the polished marble surface. It is also recommended to avoid contact with liquids and acid food and to remove immediately these substances if they accidentally come in contact with the surface.
