Cracks and Shrinnks

Artificial products have advantage of homogenization and efficient productivity, on the other hand natural products have individual differences and heterogeneous property. However, the boundaries can be changed vaguely depending on the way of thinking. I think that even substances classified as artificial could have characteristics like natural ones. Without the production loop for human selfish reasons, the mixture of artificial things and natural ones can be located as a new value. This work is a proposal of a new material for reaffirming the perspectiveon nature. The raw materials are polystyrene, which has the property of shrinking by heat, and two types of acrylic paint, which shrink and crack following it. The variations of the properties of the materials, the firing temperature and time were examined to observe the curing. The resulting texture differs depending on the temperature of the oven, the thickness and density of polystyrene, the distribution and concentration of the acrylic paint, the humidity, the temperature, and the time spent in the air. CRACKS AND SHRINKS is made of artificial materials and is made by human hands but final shape of it can not be predicted by humans. It is a new material expression in which the texture changes due to various factors.

人間の意思が入り完璧な均質化と量産に価値を見出してきた人工物に対し、個体差があり不均質だが、それが価値になる自然物。対象や視点でその二つの境界は曖昧に変化するものという観点から、人工物と呼ばれている物質でも原初的な現象によって自然観を見出すことは出来ないかと考えた。人工的な素材を使うので物質として完全な自然物を作る事は不可能だが、その要素や感覚が混在するものを作れないかと試み、利己的な理由で生産された人工物質を均質的な生産のループから外し、その素材の性質や生成における温度や時間を見直す事で素材が持つ特性や現象で起こる変化を観察した。今回、熱によって収縮する性質を持つ化学物質のポリスチレンとそれに追随して縮みや割れを起こす二種類の塗料を使用。ポリスチレンはオーブンの温度、素材の厚みや密度。塗料は配分や濃度、湿度や気温、空気に触れていた時間。CRACKS AND SHRINKSはそういった様々な要因によってテクスチャーが変化する人為的操作の及ばない物質である。
