ABSTRACT
Any material inherently comes with its physical and chemical properties. The material scientists and allied engineers work on these properties in order to unearth newer findings. The change in the properties of a material through various process directly affects its characteristics and behaviour. Significant research on material science and metallurgical engineering have been done based on physical properties of the substance. Out of many physical characteristics of materials, this paper focuses on optical properties based on human visual perception. The particular research aims at an interdisciplinary approach to investigate how visual perception plays an important role in design and analysis of materials. Two particular cases have been analysed for this purpose, one in the domain of micro structure analysis and the other relating to the external physical visual characteristics of a material. Through this analysis a generic process framework is evolved which could be applied in material research as a theoretical discourse. Additionally an expert opinion survey reinforces the establishment of the evolved process framework. It would help scientists and `engineers adapt and relate to a process so far as designing of new materials or comparative assessment of materials are concerned based on human visual perception.
INTRODUCTION Materials have various physical properties such as acoustical, atomic, electrical, magnetic, mechanical, thermal, radiological and optical properties. Optical properties of material include colour, reflectivity, transmittance etc. Based on such optical or visual properties, materials start getting its socio cultural values. Materials have strongly gained cultural significance and symbolism based on this property. Combination of other factors 1167

such as rarity, affordance and conflict combined with optical properties start deriving a particular meaning in the society. For example, platinum, when combined with its factors of rarity, production and economy with the look of the material, it becomes a very precious thing in the planet. DESIGN AND ANALYSIS OF MATERIAL New materials are designed for various purposes. For enhanced physical properties often materials are experimented with. Despite a deep understanding of the properties of individual atoms -- the 'ingredients' that make up a crystal -- scientists found that, when they are combined they
