Porcelain is composed of fine clay and a mineral called kaolinite, and can also contain many other minerals found naturally in clay. This material is made by taking the clay and the minerals and heating them to extremely high temperatures. Porcelain is very dense and non-porous; making it low maintenance, heat resistant, and stain-resistant. Porcelain is very durable and is beautifully made to look like natural stone, making it a great option for applications like countertops, shower walls, fireplace, and much more.
