Here are some important vitrification and crystallisation facts. There are two ways to achieve a polished stone finish to marble and they are: Vitrification (also known as crystallisation) which usually involves a 2 step sandwich process. How is this managed? The restorer will spray down on the marble tile an acidic solution which reacts with the calcium in the marble.
