초록
This study was to grasp the change of materiality of natural material through decomposition techniques after the raw material are extracted from natural material. In addition, it is to analyze examples to achieve the purpose that is to apply expressive possibility of new material into the space design. The results of the research are as in the following. First, the development of technology could allow use in various directions on nature material which has not been applied on architectural and spatial until now. In particular, material properties and surface design are shown differently by 'decomposition techniques'. Second, decomposition techniques fall into two categories. One can be subdivided into 'thermal decomposition, catalytic decomposition and electrolysis' that is the technology to decompose nature material with the chemical combination. Other is 'cutting, grinding, crushing and pressing' that is to dissolve nature material with physical power. Third, 'thermal decomposition' and 'catalytic decomposition' technology changed into natural ingredients which are to complement properties than raw material by removing harmful or unnecessary ingredients of nature material and 'cutting' technology changed color, form, and patterns etc hidden in natural material into the ways to express outwards. In addition, 'grinding' and 'crushing' technology confirm characteristics that are unlike earlier by vanishing most of existing properties. Forth, surface design is appeared as realistically, metaphorically, concretely, timely and autonomically. Therefore, decomposition techniques expand the area of expression by leading (inducing) differences between the change of materiality and surface design. Also it will serve as a foundation that excellent properties of natural resources appear in a positive qualities and will have a great influence on various use as an advanced material.
