Chip Data

The chips used in Terrazzo can be defined to include all calcareous, serpentine and other rocks capable of being ground and taking a good polish, e.g. marble, onyx, etc. Some other materials such as quartz, granite, quartzite and silica pebbles are suitable for those finishes that do not require polishing, such as Rustic Terrazzo. Chips are graded by number according to size in conformity with industry standards adopted by the marble producers.
