Slag is the final solid residues in furnaces after the steelmaking process. It has various forms and countless images. The work made from pieces of slag is monumental, and its dilapidated or weathered-like shape is just as a statue of ancient times. Therefore, in conception, the work seems to have a foothold on future, observing and representing the looks of industrial time where the being, variation and fadeaway of substances and values in the flow of time substantially show a kind of life’s inner misgivings.
