RATIONALIZING DEMANDS for OBJECTS and their SURFACE SYSTEMS

Post 640 –by Gautam Shah

Objects and Surfaces have their demands, which must be tackled before one can use them. Objects are used for their dimensional features, mass, form, engineering attributes, and other consecrations like cost, availability, ecology, etc. whereas the surfaces are used for sensorial purposes. Objects and Surfaces are rationalized to prepare them for technical use, handling, environment and assembly.

We do so by matching the requirements with readily available lots. However, we need to prepare, process or manufacture the objects or surfaces through several conversions. The processes of rationalizing, though begin with the object-modification, may eventually include changing the environment. Changing the environment immediately can bear upon a very vast field of actions. Like the old fable, for the king it is more efficient to cover own feet with leather shoes than layer streets of town, to protect from dirt’. ‘Similarly one may open the umbrella during the rain and not at other times’. It is more efficient to deal with the environment in space and time.

The time and effort expended in modifying the entity or its environment, is not very efficient. It is often more effective to compose a new entity (functionally, technologically and economically), than expend too much effort in improvising it. It is better to buy a new razor blade with a sharp edge, than polish the blunt one, or join a bone mechanically, than allow passage of time to do so.

Objects and the surface systems, if of single material, the operative demands are simpler, but if composed of many materials (similar or dissimilar), have complex and often in-specifiable demands. It is ideal to reform the object entity by integrating its surface systems with it. Where such one-to-one integration is not possible, the object entity and its surface system both may be individually refashioned to become each a single material entity.

A surface system can be facilitated by delaying or curtailing the effects of environment, for the functional period of the entity. Environmental effects are from specific orientation and for duration, and so a surface systems can be designed to be selectively local or dynamic. Liquids and gases have no stable object boundary, so must be contained, and for such material phases the container becomes the apparent surface system.

Ordinarily surface finishes are fashioned, only after the object and its relevant environment have been conceived. But sometimes an object could be so hazardous that until a really workable surface system is designed, the object cannot be allowed to exist or function. Similarly an environment could be so harmful that till an appropriate finish system is devised the object cannot exist, much less function in it.

The environment influences objects in such a complex way, that any search for logic is sometimes impossible. This is the reason why many surface makers seem to work with their intuitive faculties. To some people, ‘providing a surface system is an art or craft, rather than a scientific discipline’.

At any cross section of time, we find a large number of surface systems are overtly attached to the object or in the process of being integrated to the entity-base. It is very necessary that a surface system in such a situation, be singular in constitution or at least be effective in that manner. Finish makers aspire to provide a singular surface system in place of a multi-component system. However, in a finish maker’s world there are very few situations where singular surface system can satisfy all the demands. Multi-component surface systems are reality.

NATURAL OBJECTS and SELF FINISHES

NATURAL OBJECTS are created by various formative and destructive processes of nature. We pick such objects off the surface of the earth, mine them, or obtain by breaking off from a larger unit. Such objects once removed from the place of origin, invariably change further by the environmental processes called weathering effects. A freshly opened face of such objects present a surface finish, different from the face already exposed. Objects of the same specie may show up different surface finishes, depending on the angle of cut or cleavage, technique, and tools used for down sizing and finishing.

Natural objects have time and space relevance. It may not be possible to amass enough quantity within a set schedule, or may not be economically viable to transport the required type and quantity.

SELF FINISH is a surface component of the material itself. Self finishes occur on Natural, Modified and Manufactured objects. Since such finishes are integral part of the object, the engineering properties of the object continue to be affective through the surface system.

Natural and modified objects have inherent limitations, such as: Technologically, one can obtain a surface system equal to or smaller than the naturally available sizes and shape of the object. Identical surface qualities (colour, texture, pattern, etc.) are not available in every sliced section of a large object, because deeper or core regions show different surface qualities than the outer parts. Surface properties vary a little within a specie.

One adjusts such qualitative differences by randomly distributing the variant, as small components in a large composition. Though agglomerated assemblies have their own problems, of joints and joint materials.

  • Manufactured objects have self finishes. Bronze statues and outdoor objects have an induced self surface finish consisting of a green, brown, blue, and black patina of copper compounds. Silver is oxidized in an electrolytic liquid and then selectively ground to show a composition of dark (oxidized) and bright (polished) surfaces. Mild steel surfaces are burnished (burnt) to a blue finish. Iron is sometimes allowed to rust until it acquires a satisfactory colour, and then the process is arrested by lacquering. Stone washed jeans are intentionally created finishes.
