Porcelain countertop slabs are thin, dense ceramic panels fired at high temperatures. They can resist heat and sunlight well, making selected products suitable for indoor and outdoor applications. Quartz is thicker and more forgiving during some fabrication processes. Its resin-containing construction can be affected by excessive heat and prolonged exterior ultraviolet exposure. Porcelain edges and corners can chip if struck, and detailed fabrication requires specialized equipment. Quartz can also chip and should not be treated as impact-proof. The choice should consider edge style, sink fabrication, outdoor exposure, installer experience, and the specific product warranty.
Key considerations
- heat resistance
- stain resistance
- UV resistance
- thin slabs
- engineered designs
- indoor and outdoor options
