Artificial stone is a composite material in which crushed stone is held together with an adhesive to create a solid surface (most commonly polymer resins, and some newer versions use a cement mixture). This category includes engineered quartz (SiO2), polymer concrete and engineered marble. The uses of these products depend on the original stone used.

Engineered marble's most common applications are indoor flooring and walls, while quartz-based products are primarily used for kitchen countertops as an alternative to laminates and granite. Related materials include geopolymers and cast stones. Unlike terrazzo, the material is factory manufactured in either blocks or slabs, cut and polished by fabricators, and assembled on site. Processed stone is also commonly referred to as agglomerated stone or agglomerated stone, the latter term being recognized by the European Standard (EN 14618), but due to the confusion of terminology this standard does not include Materials are also included. The quartz version (which is likely to be handled directly by the end consumer) is commonly known as "quartz surface" or simply "quartz".
Manufacturing equipment Breton S.P.A. is a privately held company in Treviso, Italy that developed the large-scale Breton process in the 1960s and is a leading supplier of synthetic stone manufacturing equipment. Breton was the first manufacturer of forming equipment and still holds several international patents for its process, although several other companies now make similar machines.
Composition Granular and powdered 99.9% pure silica constitutes 90-93% by weight of the body and is dispersed in a matrix of unsaturated polyester resin (7-10%) mixed with peroxide catalyst and cobalt promoter. Accelerates curing of thermosets at ambient temperature. . The cured material is typically stored for 24-48 hours prior to polishing, and a finishing absorber is also added to the chemical mixture to prevent discoloration as a result of the reaction between the unsaturated polyester resin and UV light. Synthetic quartz stone manufactured using unsaturated polyester resin has lower water absorption, better chemical durability, higher hardness, higher bending strength, and better thermal shock resistance than granite and marble. There is a feature that
Process Compaction by an oscillating compaction vacuum process uses an elastomeric mold that casts a mixture of crushed stone and resin on a moving belt. A mixture of approximately 93% stone aggregate by weight and 7% polyester resin (66% quartz and 34% resin by volume) is heated and compacted under vacuum in a large press. Vibration helps compact the mixture, resulting in an isotropic slab that is virtually pore-free. Artificial stone is processed in basically the same way as natural stone. Some companies import their own cobblestone and grind it into lumps (stone flour) of various particle sizes to make their products, while others simply purchase already ground stone flour.
