Sintered stone countertops, also referred to as ultra-compact surfaces, compact surfaces, and pyrolithic stone countertops, are large format surfaces engineered primarily from minerals without resin binders. As described here, these slabs can be used as countertops, though they may also be used as flooring, wall paneling, and cladding. They are made by pressing very finely ground minerals and inorganic pigments into a mold under high pressure and firing the material between 1,000-1,200°C. Under these conditions, the mineral inputs sinter into a hard, durable, and low-porosity material that resembles natural stone. The content information is commonly provided in terms of the raw materials combined to make the surface and is therefore provided as such here. The firing process alters the structure of the material. While similar to ceramic or porcelain materials, sintered stone differs in mineral inputs and processing. The resulting product is very dense with designs and patterns typically propagated throughout, negating the need for printing, glazing, or sealing. The unique process also allows for large format offerings in greater thicknesses than other ceramic or porcelain materials. The exact mineral inputs and pigments vary by manufacturer and product. See the All Contents tab for additional pigments that may be used.
