Holy Quartz Co., Ltd. -

HolyStone quartz surfaces meet exacting standards of excellence from the initial procurement of raw  materials to the final quality control check. Our manufacturing process in includes the following:

Feeding & Mixing

Raw material are inspected, then fed into mixers and blended together.


The mixture is then poured into a mold and formed into slab size of 300*140cm or  320*40cm.


The slab is then compacted by a special vacuum and vibration process at a  pressure of 100 tons.


The slabs are moved to the curing klin and heated to 90 C for  25 minutes which  gives our quartz  slabs ultimate strength and solidity.


Slabs are then gauged, calibrated and polished to a perfect finish in a wide range of  colors and designs in one of our three textural surface finishes: Polished, Honed.
