The Vitrification or crystallization is the method to achieve a high gloss finish. This procedure is recommended by NYC Stone Care to be applied as a regular maintenance in high traffic areas that requires constant shine such as hotel lobby.
In order for this method to work we need to create a chemical reaction on the surface of the stone with the help of steel wool and formulated chemical compounds. The only stone that can’t be vitrified is Granite. Marble, travertine and most limestone can be perfectly vitrified because they contain calcium carbonate.
