Earthenware: This type of ceramic is very porous and brittle, so it has to be fired and glazed. Because it is porous however, it is also able to soak up bright colors and produce bold ceramic pieces. Stoneware: This type of ceramic is waterproof, smooth, and has a higher firing temperature than earthenware when out in a kiln. Porcelain: This type of ceramic is one of the most durable types, and is commonly used for purposes such as dinnerware, bathroom toilets and sinks, and dentistry (fillings for cavities). It also has a high firing temperature, is translucent, and no-conductive after firing.
