.History_and_development_of_Artificial_StonesFinishes are inherent on natural objects or fashioned out of such objects. Objects are also produced with required finishes, or the manufactured objects are finished with desired quality of surfaces. A surface finish nominally represents the nature of the material, however, many finishes are pseudo or make-believe effects. These are imposed on the objects. The relationship between the ‘nature of the material’ and its surface quality, some times it becomes a restrictive condition.

Processes for Natural Surface Finishes: Natural Finishes result due to many different factors, such as: Elemental conditions of formation, subsequent responses like weathering, cognitive affectations, and later, natural or man-made interventions (angle of cut, tools and techniques used, etc.).

Natural surface finishes have three main cognitive affectations: Colour, Pattern and Texture. The colours are of original formation, subsequent weathering, readjustment of stresses, or induced by physical and chemical changes. The patterns result from the stresses, mixing of constituents, weathering, and the varied reactivity of different parts and constituents. Patterns also result from granular or fibrous orientation, method of cut, cyclic nature of growth, formation of residual products, deposition of contaminants, and tools-techniques of handling and processing. Textures primarily result from the degree of homogeneity, angle of cut, differential weathering, and various formative processes.

Processes for Manufactured Surface Finishes: Manufactured Surface Finishes result at three levels: Raw material stage, Product formation stage, and later, through Application of surface finish on Completion of the system. In an integrated production set-up all three could be a single stage or plant process, but in most other fabrication shops only the last two processes are combined. For a site fabricated systems like buildings, the last process, i.e. surface finish application, is a distinct process as it is carried out at a site. Manufactured surface finishes as a result are of two categories: Plant based and Site-based systems. Though lot of preparatory work may occur in the industrial plant for the site-based surface finish application. Products fully surface finished in industrial plants require very careful handling (transportation, loading, storage, delivery and positioning), and so may carry protective but removable coatings or shields.

Make-believe or pseudo finishes: These finishes are of two basic types:

● Surface finishes that duplicate the natural materials, such as: wood figure (pattern) or texture effects in polymers, stone like effects in ceramics, cotton like fabrics made out of polyester, or synthetic gems and diamonds.

● Surface finishes that copy the effects of other manufactured finishes, such as: chrome polymers for metals, white metal ornaments for silver, or acrylic for glass. Future possibilities include flexible glass, elastomeric metals, polymers with programmable colouring or texture forming system, metals lighter than ceramics or polymers, biodegradable ceramics, etc.
