What Is the Difference Between a Quartz Slab and a Porcelain Slab?

Quartz stone is currently one of the most popular materials in the kitchen and bathroom space, with a more balanced appearance and performance that is well-liked by customers. Rock slab is a relatively new material that has just gained popularity in the last two years. Rock slab brother believes that in the coming years, rock slab will have a significant impact on quartz stone material, and it may even replace quartz stone.

The following comparison will help you grasp the difference between rock slate and quartz stone based on composition, production environment, appearance, performance, application, and other factors.

1、Composition.

Natural stone powder, clay, and other materials are the primary components of rock slabs. Quartz stone is primarily made out of natural quartz, resin, curing agent, and other ingredients.


2The production environment

Rock slabs are produced by burning at a high temperature of over 1200 degrees Celsius in a 10,000-ton press (15,000 tons or more). Quartz stone is created using a vacuum press, followed by heating and curing.


3. Physical appearance.

Rock slabs are typically huge in size, with thicknesses ranging from 3 to 20mm; the pattern is similar to natural stone, and the blank and surface color is continuous throughout the body. The look of quartz stone is richer in color, but the texture and natural stone are more dissimilar, with thicknesses ranging from 8 to 30mm.


4、Performance.

The rock slab's performance is comprehensive and outstanding: waterproof, fire, high-temperature resistance (1200 °C), low-temperature resistance, high concentration of acid and alkali resistance, anti-seepage stain, wear scratch, impact resistance, can be in contact with food, no radiation, environmental protection, can be 100 percent recycled, durable, and non-fading.

When compared to a rock plate, the performance of quartzite is poor, such as open fire can be ignited and release the smell of paint, high temperature will be discolored, yellowing aging can withstand low concentrations of acid and alkali, high-temperature resistance of 300 °C, not resistant to oil; waterproof, wear-resistant scraping performance is not bad.


5、Application.

Because of its high performance and plasticity, it can be deeply processed and utilized not only as a decorative material but also as the main structural material. It is extensively used in countertops, tabletops, walls, floors, door surfaces, and other industries. Quartzite is commonly used for countertops and tabletops.

In conclusion, while both rock and quartz stones are man-made panels, the differences in production environment and procedure have resulted in varied performance and texture, as well as a variation in market value.


Quartz stone has become one of the most popular materials in the national kitchen and bathroom sector, whereas rock slab is a new material that was introduced to China from Europe only a few years ago. With the present market trend, rock slabs are becoming increasingly popular among customers, designers, and home customization makers, and are on the rise.
