Authentically crafted fireclay sinks are made of a unique clay capable of being fired at extremely high temperatures. These high temperatures cause the clay and glaze to fuse together, virtually creating an entirely new form. This clay is found in limited regions around the world, making true fireclay sinks some of the most durable sink options. Resistant to acid, alkali, scratches and impact many fireclay sinks outlive the very spaces for which they were created. ROHL's fireclay sinks are crafted with environmentally friendly materials and are completely lead free and recyclable.
