Custom High Hardness Artificial Quartz Slab Class A Crack Resistant
Quartzite is a naturally occurring metamorphic rock. It is created
when sandstone is subjected to extreme heat and pressure caused by
tectonic plate compression in the crust of the earth. The stone is
mined and sawn into slabs which are later precisely cut to become
countertops. The tops are polished and sealed for beauty and
Quartz countertops are often called artificial countertops because
they are fabricated from natural silicon dioxide and synthetic
materials. Our quartz slabs made up about 93 percent of the
Mohs: around 6-7
Slab size: 1.6*3.2m
Welcome CUSTOMIZED DESIGNS, There are more than 100 pcs of patterns
available now in our factory.
Quartzite is generally found in white to gray. Pink and red hues
are a result of iron oxide in the stone.
Yellow, blue, green and orange quartzite results from the presence
of other minerals. Regardless of the color, the quartzite will have
streaking caused by varying degrees of pressure in its formation
and the random presence of iron oxide or other minerals.
Quartz, because pigment can be added, is available in a much wider
range of colors for you to consider. The way the countertop
material is formulated gives it the appearance of natural stone
such as granite or marble.
Hardness and Durability:
Quartzite is harder than granite, so it is quite durable. It
withstands heat very well. Quartz is hard too, but not quite as
hard as quartzite. The resin used in manufacturing quartz
countertops is a plastic, so it is prone to melting in heat above
300 degrees Fahrenheit.
Where quartz has an advantage over quartzite is that it is less
prone to denting and chipping because it is more flexible. Both
countertop materials can be scratched by sharp objects, and a
cutting board should be used.
Quartz requires very little maintenance. It wipes clean with a damp
cloth. Abrasive cleaners should not be used on quartz, and they
really aren’t needed. Ease of maintenance is the main advantage
quartz countertops have over quartzite.
