Porcelain crystal stone is an example of metamorphic group stones that this stone formed under heat and pressure and then become new stones with new features and characteristics.
Crystal stones, which are same as porcelain stones, are obtained from transformation of marble stones, and in this process, make new stone that has large and visible crystals. In fact, these types of building stones belong to the marble stone group. And this stone is different in each region and mine in terms of their degree of metamorphism and chemical composition.
People who see porcelain stones and don’t know about building stones, they think these stones are imported from china, and this is a common mistake that is seen and heard about this stone.
