Dolomite washbasins are conglomerate sinks. They are produced from polyester resins filled with calcium and magnesium carbonates and quartz flour with various granulation rates. Physical and chemical properties of polyester conglomerates have features similar to natural granite. In many respects, it outweighs granite (eg the lack of micropores found in natural granites, which are the habitat of bacterias). The top surface is covered with a layer of sanitary coating. The external coating is dyed in the technological process and is characterized by high hardness, high gloss and it is easy to clean. The color is resistant to the influence of UV radiation. The distinctive feature of dolomite washbasins from ceramic counterparts is the ability to give them attractive shapes. They have clear, straight edges and a smooth surface. As a result, such sinks are especially attractive to bathroom furniture.
