Casainc fireclay sinks are kiln-fired at high temperatures of 2200°F and feature solid core construction that makes them highly resistant to impact and thermal shock. At the same time, using advanced glazing technology to create a durable, non-porous finish against scratches, rust, and stains, it will not yellow or fade over time. These properties make Casainc Fireclay sinks a superior choice compared to alternative materials such as cast iron enamel and ceramic sinks, which can easily chip or crack. The 36-inch fireclay sink gives you plenty of usable space for filling pots, stacking dishes, and preparing meals.
