Marble is a softer and more porous surface than granite or quartz so it can wear slightly. Part of marbleâs charm is its changing luster as it ages, though it can always be re-polished and restored to its original shine. Marble typically requires sealant every year as well.arble is a metamorphic rock composed of recrystallized limestone or carbonate minerals, such as calcite and dolomite. When these rocks are exposed to extreme temperature and pressure, the recrystallization process forces each molecule closer together and forms an interlocking carbonate crystal structure.
Porous ceramics are made by the sol-gel process. These ceramics have spongelike structures, with many porelike lacunae, or openings, that can make up from 25 to 70 percent of the volume.The pore size can be large, or as small as 50 nanometers (2 Ã 10 â6 inches) in diameter.anufacture of Traditional Ceramics. Traditional ceramics are made from natural materials such as clay that have been hardened by heating at high temperatures (driving out water and allowing strong chemical bonds to form between the flakes of clay).
