On the surface fireclay sinks may look like cast iron sinks, but their material and construction processes differ. Fireclay kitchen sinks are made by molding clay into the shape of a kitchen sink, adding a glaze, and then firing it at temperatures higher than cast iron sinks. This process allows the clay and the glaze to bond with one another, essentially becoming “one”, and results in a heavy-duty sink.
Fireclay sinks are tougher than cast iron sinks, but they come in fewer color options and are more expensive. They are mostly found in apron front/farmhouse style and in white. Their ultra tough nature might not give you as much flexibility against the vibrations of a garbage disposal. As such, they can crack if you install a garbage disposal too tightly. But they will not rust when cracked like cast iron sinks because they aren’t made of metals.
