Today's top-of-the-line premium home appliances all have one thing in common. Know what it is? It's a 4,000-year-old material that protects and beautifies. All the latest appliance innovations, whether a refrigerator, stove, dishwasher, microwave or washer and dryer, feature gleaming finishes and vibrant colors. The best of these all feature one thing that ensures easy care and long-lasting beauty: A porcelain enamel finish on all key surfaces, inside and out. And the process, which permanently fuses a molten glass composite to red-hot sheet steel, offers a rock-hard surface that resists staining, cuts and scratches, color fading and corrosion. It was first used by the Egyptians back in 4,000 BC, and many of their pieces still retain their original form and beauty. Want a finish that will endure and last for ages? Think like the Egyptians -- buy porcelain enamel. For more tips, visit our Web site at onthehouse.com. And that's the On The House tip for today.
