Does green Marble require special treatment?

Some green stones, such as the “jades” from Taiwan, are not truly marble, but a different material called serpentinite. Serpentinites, or serpentines, as they are sometimes called, do not etch or react to acids the way limestone and marble do, and are somewhat harder. Green tiles of this family must always be installed with an epoxy adhesive to prevent the curling that can take place if a water-based setting material is used.
