Quartz worktops are made of pieces of natural stone bonded together with a small amount of adhesive. The stone used is quartz, one of nature’s toughest materials, and a very versatile one. Quartz worktops are 90-99% quartz. The exact ratio depends on the manufacturer and type of quartz worktop. As an example, Samsung Radianz Quartz is 93% quartz, as it is quite fine grained.
Marble cladding and marble flooring can be primarily composed of one or more carbonate materials such as dolomite or calcite. The purest calcite marble is white, but there are usually patterns found in marble to give it its unique look in a marble worktop. The crystallisation process of marble gives it more solidity. Not only that, but it allows the stone to be polished up far more brilliantly than other materials.
