Sintered stone is an ultra-compact and high performance surface product that is made entirely of natural materials through a special process called Sintering. The sintering process involves the crushing of natural materials under immense pressure (over 6,500PSI) and baking in extreme high temperatures (over 1250°C) . By exposing natural materials to extreme pressure and heat, the end-product forms a solid, impenetrable surface, and becomes Sintered stone which is extremely hard to scratch, burn, or stain
