Porcelain countertops are made from non-porous ceramic clay that contains various minerals, such as kaolinite and silica. As with all-porcelain products, the material is baked in temperatures ranging from about 2200-2650 Fahrenheit. These extremely high temperatures produce a durable countertop material that is resistant to scratching, cracking, UV light, and heat. It also offers resistance to staining.

With porcelain countertops, you really only have two edge options: square or mitered. Because the material is so thin, manufacturers will often create a mitered edge to give it a thicker look. You don’t have as many finish options for porcelain countertops as you do with quartz or natural stone.
