Thermal paper, what recipes or tickets are made of, is a material that has been widely used in our everyday life. Piling up layers of thermal paper and scraping them with the belt sander, I found an unexpected phenomenon, the emergence of a wood grain pattern. This thermal paper stool is the first product utilizing this phenomenon. This phenomenon was discovered while I was experimenting with different types of paper. The belt sander, spins at high speed, generates heat while contacting with the thermal paper. This heat burns the paper and leaves black burn marks. Then, the black burn mark shrinks, getting to the bottom layers, due to the reduction of the quantity of heat. The gradual shrinkage of the burn marks overlaps and the wood grain pattern emerges.  Roll paper is a product of industrial manufacturing, yet through the growth ring pattern, I have the impression of natural spirits inside this artifact. Originally, thermal paper is been used as the media for printing and the belt sander is a tool to make smooth the material surface.  However, the identity of the thermal paper and the belt sander is altered in this product. They become stool legs and a tool generating patterns. By redefining the existing artificialities, we can create new objects that didn’t pre-exist in nature yet maintaining a natural spirit. I think through this method, the possibilities to create new materials and new designs could be expanded.
